This analog input module supplies intrinsically safe signal conditioners in hazardous areas classified as Zone 0 and Zone 1, and processes their analog measurement signals. The WAGO I/O System 750 XTR must be installed either in Zone 2 or in a non-hazardous area. The 24 V supply voltage is fed in via the power jumper contacts. The transmitter power supply is conditionally short-circuit protected. The shield connection directly connects to the DIN-rail. Indicators: Green LED (availability ON/OFF) Red LED (measurement range overflow/underflow, wire breakage, short circuit) Field and system levels are electrically isolated. The device is ideal for operation in extreme environments thanks to: An extended temperature range Greater immunity to impulse voltages and electromagnetic interference Higher vibration and shock resistance
