2200-093 GMA 200-MW4/3 Controller, Configured for 3 Measuring Points, Supply Voltage, 110 V AC, with Internal Power Supply by GfG

The GMA 200 offers innovative technology and trend-setting flexibility. It is designed for commercial and industrial applications for the measurement of combustible and toxic gases as well as for the measurement of oxygen. The compact construction of the GMA 200-MW4 provides a cost-efficient solution for safe gas monitoring of small facilities.

Parallel measurement and flexible application

With the GMA 200-MW4 up to four different transmitters can be monitored simultaneously. They can be connected analog or digital to the GMA 200-MW4. Using the configuration software for every connected single transmitter the measurement range, the measurement designation, the type of transmitter and the type of gas can be set individually and three alarm thresholds can be programmed. The microprocessor of the GMA 200-MW4 evaluates all receiving signals and activates alarm or relays. In doing so one single GMA 200-MW4 can master different gas detection tasks.

Integrated relays

GMA 200-MW systems include comprehensive and fully programmable relays. Each GMA 200-MW4 controller is equipped with six internal relays. For the implementation of safety measures and alarm, four relays can be freely programmed so that in case of alarm the safety measures can be triggered automatically.

The programming grants wide-ranged and flexible possibilities such as the allocation of one or more measurement points to relay, single alarm per measurement point, configuration of collective alarm and group alarm, error report and voting function. For each, safety related error report and and maintenance, there is one additional relay available.

Relay modules

The GMA 200-RT relay module can be added and adds an additional 16 freely configurable relays. A total of four additional relay modules (for 64 additional relays) can be managed by the same GMA 200-MW4. Digital interface (RS485) with the GMA 200-RT relay module allows decentralized installation of the relay modules, which offers great flexibility and reduces cabling and installation costs.

GMA 200-MW4 Controller

In addition to the traditional power supply the GMA 200-MW4 can be operated with a redundant, safety-oriented power supply. Based on this the GMA 200-MW4 meets the highest safety requirements and guaranties a permanent availability of gas detection systems for potential gas hazards.

LED indicator lights

LEDs show the Status of the GMA 200-MW4 controller (including operation, fault, service alarm and relay status).

Graphical display

Currently measured values are displayed on a backlit, graphical LCD. In the event of an alarm the display changes color from green to red, and highlights the affected channels. Furthermore the display of alarm 1, alarm 2 and alarm 3 occurs on the LED graphic display. Simultaneously the status of the affected channels 1-8 is shown by the LED lamps in the case of alarm.

The integrated storage allows the reading of alarm stages.

Datalogging standard

Measured values, mean values, alarm events and faults are permanently stored on a microSD memory card.

Operation via keypad

Operation of the GMA 200-MW4 is through easy-to-use menus, and a simple five button interface. Main functions of the keypad are the alarm acknowledgement, and viewing information on the status of the controller, the transmitter and the relays through the operation menu.

Configuration

A built-in USB port in the GMA 200-MW4 is used for connection to the configuration software.

GMA 200 bus interfaces (RS485)

There are three RS485 interfaces on the GMA 200-MW systems.

2 x TRM - BUS

The TRM-BUS allows the connection of up to 16 digital Transmitters. They can be connected in loop structure or line structure to the GMA 200, so that there is a wide range of possible connections. In addition, every TRM - BUS offers integration of the external relay module GMA 200-RT / RTD.

1 x GMA - BUS

In addition to the option to use this BUS for the connection of an external relay module, this interface also offers the option to integrate the GMA 200 controller into a network of facilities. A Modbus protocol in the RTU - Mode, which is transmitted through the GMA - BUS interface allows status readings of the GMA 200 controller by using a PC. Additional gateways are offered by GfG and enable the digital status monitoring and data processing using additional external modules (e.g. PLC).

GMA 200 Visualization

Complex Gas Detection Systems with several controllers and numerous different transmitters call for a clear overview to guarantee safety. The rapid and precise localization of gas hazards is critical to protect facilities, environment and human life. The PC - based Visualization Software, GMA 200 clearly displays the status of the entire Gas Detection System. If any alarm threshold is exceeded, the alarm triggers a measuring station with associated designation, the measured value, the measured unit (% vol. or % LEL) and the type of gas is displayed immediately on the screen, so that appropriate measures can be taken quickly.
