| 2-CHANNEL ANALOG INPUT MOUDLE 4-20 mA |
The analog input module provides the power to the intrinsically safe transducers located in the hazardous area of Zone 1 and process their analog signals. WAGO-I/O-SYSTEM 750 has to be installed in Zone 2 or in non-hazardous environments. The 24V supply is derived from the power jumper contacts. The transmitter supply is non-inherently electronically short-circuit-protected. The shield (screen) is directly connected to the DIN rail.
Indicators: Green LED (signal on/off) Red LED (wire breakage, measuring range overflow/ underflow)
Each input is electrically isolated from the bus by use of optocouplers.
Note:Only use the digital input module in connection with the 24V DC EEx i supply module
750-625 . |

| Power Supply Instructions |
When operating the intrinsically safe EEx i modules in connection with sensors/ actuators operating in hazardous environments of Zones 0 and 1, the supply module 24V DCEEx i (
750-625 ) must be used to supply the I/O modules.
Note:
If further 24V DC EEx i supply modules are required, four separation modules (
750-616 ) must be placed between the intrinsically safe sections. |
