1.2 Application and purpose

GMA200-RT and GMA200-RTD are relay modules in the mounting rail housing which can be used as an
extension of the relay outputs to the gas detection controller (e.g. GMA200-MT6). The relay modules
GMA200-RT are connected directly to the gas detection controller via a plug-in connection or a bus cable.

1.3 Special conditions for safe application

Important information:

The gas detection controllers GMA200-MT/-MW are not described in this user manual.
(see UM 222-000.20).

The configuration software GMA200Config is not described in this user manual.
(see UM 222-000.30).

2. Relay modules GMA200-RT/-RTD

2.1 General description

The fundamental configuration and design of the gas detection controllers GMA200-MT/-MW in combination
with the relay modules GMA200-RT/-RTD ensure flexible, simple and clearly structured operation in
industrial and commercial applications for measuring combustible and toxic gases/vapours and oxygen
concentrations.

In addition to the internal relays of the gas detection controller of the GMA200-MT/-MW, the relay modules
GMA200-RT/-RTD can be used for extension purposes. The relay modules GMA200-RT/-RTD are connected
directly to the gas detection controller via a plug-in connection or a bus cable.

The relays are managed via the microprocessor of the gas detection controller GMA200-MT/-MW and
activated in the event of an alarm or a fault.

The relay module GMA200-RTD is equipped with an integrated graphical display.

2.2 Device design

The relay module GMA200-RT/-RTD enables the addition of a further 16 freely configurable relays. A total of
4 relay modules with 64 additional relays can be managed via the controller GMA200-MT/-MW. The relay
modules GMA200-RT are connected to the controller GMA200-MT/-MW via the digital interface RS485, which
also enables the spatial separation of the relay modules (max. 1,000 m).

The optionally available display at the relay module GMA200-RTD enables, amongst other things, the local
display of measured values (see section 2.2.2) which are transferred by a gas detection controller GMA200-
MT/-MW via the digital interface.

2.2.1 LED status displays

During operation, LED status displays at the relay module GMA200-RT/-RTD indicate the following statuses
according to the event:



Operating status (ON)

→

green



Service (SRV)

→

yellow



Fault (FLT)

→

yellow



Relay 1..16 (R1..R16)

→

red

(Relay activated in the case of an alarm or fault)

2.2.2 Graphical display at the relay module GMA200-RTD

The gas detection controller GMA200-MT/-MW retrieves and displays the current measured values per
measuring point on the display. The display for the measuring points can be optionally set via the menu
navigation (also see section 4.1), e.g.:

2.2.3 General information about the measured value display

Operation of the graphical display is locked:



If the keyboard at the gas detection controller GMA200-MT/-MW
is/has been operated at the same moment or within the last minute.



When activating the main menu or using the service menu
of the gas detection controller GMA200-MT/-MW, the
connection to the relay module is interrupted and shown on
the display.

After the display is shown and one of the arrow buttons has
been clicked, the display changes to the measured value display
and the display can be operated.

2.3 Relay configuration

The configuration of the relays is not described in this user manual. The function under which conditions the
relays are switched and whether they are used according to the closed-circuit/open-circuit principle is
configured in the gas detection controller GMA200-MT/-MW using the GMA200Config software.

3. Assembly and installation instructions

3.1 Site of installation

The GMA200-RT and GMA200-RTD are designed for assembly on a mounting rail in a control cabinet or a
wall-mounted housing and should not be installed in potentially explosive atmospheres. They should be
installed in areas with as little vibration as possible.

3.2 Electrical connections

The connection of the voltage supply and the application of the relay contacts take place according to the
terminal assignment diagram which is also located at the GMA200 housing near the terminal covers.

This symbol shown on the terminal assignment diagram means:

General warning, see user manual

3.2.1 Safety information

Electrical installation must always be carried out to DIN VDE 0100 or a similar country-specific
standard. Cables with hazardous live voltages, e.g. 230 V AC, and cables with non-hazardous
live voltages, e.g. 24 V DC, must be laid separately. The applied cables must be suitable for the
connected transmitters or devices.

If maintenance work is carried out at the GMA200-RT/-RTD during operation, please note that hazardous
live voltages may be present at the relay terminals Y17-69. Never come into contact with these terminals.

No data from

the GMA200-M

available

3.2.2 Floating relay contacts

Additional external warning equipment, e.g. control lamps, acoustic signal transmitters, etc.,
can be connected to the terminals Y17-69 (contacts of the relays 1-16). The contacts of the
adjacent relays 1&2, 2&3, 4&5, 5&6, 7&8, 8&9, 10&11, 11&12, 13&14 and 14&15 should only
be operated with the same voltage category.

Hazardous live voltages (e.g. 230 V AC) and protective extra-low voltages (e.g. 24 V DC) should not be
connected together at these adjacent relays.

3.2.3 24 V DC voltage supply

The GMA200-RT/-RTD is usually supplied with voltage via an external 24 V DC power supply unit or a
24 V DC power supply network. This voltage is connected to the terminals Y12 (24V

1) and Y11 (GND). A

second 24 V DC power supply unit or a second 24 V DC power supply network can be optionally connected
to the terminals Y13 (24V

2) and Y14 (GND). The used power supply unit should comply with EN60950-1

or feature reinforced or double insulation between the mains supply circuit and output voltage circuit similar
to devices of protection class II (protective insulation ). If the GMA200-RT/-RTD is operated in a 24 V DC
power supply network, it must be safety extra-low voltage (SELV) or protective extra-low voltage (PELV).
Otherwise, the same requirements as for the previously described power supply units apply to the 24 V DC
power supply network.

3.2.4 Connection at the gas detection controller via digital

interface

(RS485)

As the relay module GMA200-RT/-RTD is used as an extension of the gas detection controller (e.g. GMA200-
MT6), a respective communication connection must be established between both devices.
In  the  simplest  case,  the  relay  module  can  be  connected  directly  to  the  GMA  bus  connector  of  the  gas
detection  controller.  If  this  is  not  possible  due  to  the  spatial  limitations,  a  cable  with  pluggable  terminals
(GMA200-BC, see section Accessories and  Spare Parts) can be used for the bus connection.
If  the  relay  module  GMA200-RT/-RTD  should  be  connected  at  the  TRM-Bus1  or  TRM-Bus2  of  the  gas
detection controller, it must take place via a cable and pluggable terminal (GMA200-BC, see above).

3.2.5 Using the alarm acknowledgement input

A  freely  configurable  input  for  connecting  an
external  acknowledgement  button  is  available
at terminal Y15. The function of this input can
be  configured  in  the  gas  detection  controller
(e.g.  GMA200-MT6).  This  input  must  be
connected to GND to acknowledge alarms.

3.3 Commissioning

Commissioning can commence after assembling the GMA200-RT/-RTD and establishing a bus connection to
the gas detection controller (e.g. a GMA200-MT6) and once the supply voltage has been connected.
The gas warning system must be inspected and commissioned by an expert after installation. Inspections
must be carried out in accordance with the manufacturer's instructions and executed by a fully trained and
qualified expert. The expert must record the result in writing (see data sheet T023/2009, section 8.1 and
DIN EN 60079-29-2, section 8.9). GfG service technicians as well as experts authorised by us are at your
disposal.
