Working Principle Field signals enter terminals; after filtering and programmable gain, 16-bit ADC samples to digital values uploaded to the controller over the backplane. Thermocouple channels apply cold junction compensation; RTD channels use constant-current excitation. Diagnosis circuits identify loop faults. LEDs indicate channel status.
Installation Requirements
- Insert rack I/O slot with power off
- Shielded twisted pair signal wires
- Separate signal and power cables
- Rack grounding
- Temperature 0 °C to +60 °C
- Configure channel type and range in software
- RTD three-wire connection
Precautions
- Do not hot-swap online
- Signal type must match configuration
- Wear ESD wrist strap
- Verify channels from software after replacement
- Store spares in anti-static moisture-proof packaging
- Periodically calibrate accuracy
