Description
This Thermocouple Input module is ideal where only a single temperature (or voltage or current) needs to be monitored.
It also has an integral Digital Input channel to accept an input from a switch/relay or similar, along with 2 Digital Outputs which can be used for Alarm Output.
Features
- 16 bit ADC
- 3000V dc inter module isolation
- Integrated digital input and output
- Event counters
- Autonomous alarm output
- Direct measurement of thermocouples, voltage and current
- Cold Junction Compensation for thermocouples
- Can be Configured using simple ASCII Commands
