$0.00
The GMA200 Series is a fixed-system controller for monitoring combustible or toxic gases and oxygen concentration across up to 16 digital or analog transmitters.
The GMA200-MT16 is a sophisticated controller designed for complex gas detection systems that monitor combustible or toxic gases and oxygen concentration. It supports up to 16 digital transmitters via RS-485 (Modbus) or analog transmitters via 0.2-1 mA or 4-20 mA input. Features include 8 integrated relays (6 programmable), color-backlit 2.2-inch display with 15 status LEDs, audible alarm (70 dB), and DIN rail mounting. Optional data logger with microSD card stores measured values and alarm events. Suitable for any GfG transmitter with ATEX II (2) G certification and SIL 2/3 rating. Supply voltage: 24 V DC.
