The Honeywell 8C-PAIMA1 (Part No. 51454473-175) is a precision low-level analog input module designed for Series 8 C300 controller systems. It provides 16 isolated channels capable of reading thermocouple (types J, K, T, E, R, S, B) and RTD sensors (2-, 3-, and 4-wire). With features like cold-junction compensation, signal linearization, and 500 V galvanic isolation, it's engineered for high-accuracy temperature measurements in harsh industrial environments.
