Integrated controller based on the GMA 200 MT model for up to 16 channels for fixed gas detection systems that are easy to install and manage, with different output options such as relays, 4-20 mA analog outputs, RS 485, among others. Ideal for medium and large systems that require different transmitters with different technologies and measurement parameters:

  • Integrated system in NEMA 4X cabinet (Optional) with GMA 200 MT controller with up to 16 channels for connection of up to 16 GfG transmitters (It can be configured for a smaller number of channels)
  • Compatible with GfG transmitters for Combustible, Toxic and Oxygen sensors.
  • Detection range depending on the sensor in ppm, % LEL, % Vol. or mg/m3
  • Input of 16 analog signals of 4-20 mA or 0.2-1 mA and maximum input resistance of 50 Ohms
  • 2 digital inputs and 2 RS 485 BUS inputs for connection of external relay modules or digital transmitters in BUS connection
  • 1 RS 485 input for digital transfer of measurements and output data to a higher level control center or for connection to master relay modules.
  • 1 RS485 ModBUS output
  • 6 output relays (NO) fully configurable for a measurement point, an alarm value or collective alarms of several points
  • 1 output relay for faults (NC)
  • 2 fully configurable 4-20 mA analog outputs with 600 Ohms resistance.
  • Option of relay modules increasing up to 64 relays per GMA 200 MT system (Using 4 additional relay modules)
  • 3 independent alarms for each measurement point (AL1-AL2-AL3) completely configurable in the measurement range of each transmitter
  • Operating temperature from -20 to 50°C
  • Logging capabilities with microSD slot with configurable intervals from 5 s to 60 min and logging of instantaneous, average, maximum and minimum value
  • Logging functions independently configurable for each channel
  • LCD digital display with 5 buttons and LED indicators for status, alarms and relay condition (A total of 16 LEDs)
  • Integrated siren and light for audible alarm of 90 dB at 1 m and visual with 960 lumens LED
  • Mini USB connection for parameter configuration via software with the option of saving different configurations
  • Operation by current 110 V AC
  • Degree of Protection NEMA 4X (It can be configured with a Polycarbonate cabinet, IP 68, NEMA 6P, 4X, 4, 3R or 12)
