Wago 750-487/003-000 WAGO I/O-SYSTEM 750 Intrinsically safe Analog Input Module

 

2-Channel Analog-Input Intrinsically safe, Signal: Thermocouple/Low voltages Thermocouple type: K configurable: J/B/E/L/N/R/S/T/U, Voltage sensors: +-30 mV/+-60 mV/+-120 mV, Temperature range: depends on type -100..+1.800C, Sensor connection: 2x (2-conductor), Internal resistance: 1000 kOhm, Resolution: 0,1C or 0,01 mV for voltage measurement, Conversion time: 320 ms, Conversion time : <=320 ms (both channels), Temperature coefficient: <+-0,2 K / K of largest output area (Typ K), Intrinsically safety Ex i: yes, Cold junction compensation: intern at each pair of terminal blocks

 

General Description

The analog input module directly connects two thermocouples operating in hazardous environments of Zones 0 and 1.

The WAGO-I/O-SYSTEM 750 must be installed either in Zone 2 or in a non-hazardous area.

Internal electrical isolation allows operation of grounded sensors. The module automatically linearizes the entire temperature range.
Cold junction compensation mitigates the clamping unit offset voltage over the 0-55C operating range.

The 24 V supply is derived from the module's power jumper contacts. Field and system levels are electrically isolated.

The module's operating mode is parameterized via WAGO-I/O-CHECK 3 software.

LEDs:

  • Green LED (availability ON/OFF)
  • Red LED (wire breakage, measurement range overflow/underflow)

Note: The analog input module must only be operated via Ex i 24VDC power supply!

General information (e.g., installation regulations) on explosion protection is available in the WAGO-I/O-SYSTEM 750 manuals!
