Allen-Bradley|1771-IXHR| Thermocouple/Millivolt Input Module
Allen-Bradley 1771-IXHR High Resolution Thermocouple/Millivolt Input Module
Description
The Allen-Bradley 1771-IXHR is a single-slot, intelligent block transfer analog input module that interfaces up to eight differential thermocouple or millivolt signals with Allen-Bradley programmable controllers supporting block transfer.
Features
- Supports Types B, E, J, K, T, R, and S thermocouples and ±100 mV inputs
- Cold junction compensation and open-circuit detection
- Software calibration with no potentiometers
- User-selectable alarms and programmable filters
- X10 zoom in millivolt mode
Technical Specifications
- Input Channels: 8 differential
- Input Ranges: Thermocouples (B/E/J/K/T/R/S) or ±100 mV
- Resolution: 0.1°C/°F for temperature; 1 µV for millivolts
- Data Format: 2’s complement binary only
- Update Time: 25 ms per module
- Backplane Power: +5 V DC, typical current draw 300 mA
- Isolation: 1500 V AC between field and logic circuits
- Operating Temperature: 0 to 60°C
- Storage Temperature: –40 to 85°C
- Compatibility: Works with PLC-5 and SLC 500 (not recommended for PLC-2)
- Communication: Block Transfer Read/Write (BTR/BTW) instructions
- Chassis Support: 1771-A1/A2/A4 and A1B/A2B/A3B/A4B series
