750-489 - 4-channel analog input; RTD/TC/Strain Gauge; 16 bits; Diagnostics; Intrinsically safe

  • Brand: Wago
  • Product Code: 750-489
Description: This analog input module directly connects resistance thermometers, thermocouples, millivolt sensors, resistors, resistor bridges (strain gauges), potentiometers and PTC thermistors operating in the hazardous environments of Zones 0 and 1. Cold junction compensation for the respective channel is incorporated into the module. The WAGO I/O System 750 must be installed either in Zone 2 or in a non-hazardous area. The 24 V supply is derived from the modules power jumper contacts. The shield directly connects to the DIN-rail. The parameters are set via the GSD file, e!COCKPIT or WAGO-I/O-CHECK. Indicators: Green LED (availability ON/OFF) Red LED (underflow, overflow, measurement range overflow/underflow) Field and system levels are electrically isolated. A functional galvanic isolation is provided between the channels.
