Overview:
The Honeywell CC-PAIM01 module is a low-level analog multiplexer with a PMIO (Process Manager Input/Output) interface, supporting up to 64 input points. It is capable of handling both thermocouple and RTD input signals and offers features such as cold junction compensation and OTD (Open Thermocouple Detection) protection.
Key Features:
- Fast 1-second PV scanning for efficient data acquisition.
- Configurable OTD protection to safeguard against open thermocouples.
- Fully isolated channels to prevent interference.
- Low error rate with a 0.05% full-scale gain error.
- Excellent temperature stability at +/-20 ppm/°C.
- Long-term drift of 500 ppm for reliability.
Technical Specifications:
-
