The CC-PAIM01 (51405045-175) is a high-precision low-level analog input module within the Honeywell Experion PKS Series C I/O system. It is specifically engineered for millivolt signal acquisition, making it ideal for direct interfacing with sensors such as thermocouples, strain gauges, and other low-output transducers.
With a 16-bit resolution and a measurement range of -100 mV to 100 mV, the module delivers highly accurate and stable signal conversion for demanding process control applications. This enables precise monitoring in environments where small signal variations are critical to system performance.
A key feature of the CC-PAIM01 is its 1500V DC channel-to-channel isolation, which effectively eliminates ground loops and protects both the module and the C300 controller from electrical disturbances originating in the field. Combined with its wide operating temperature range (-40°C to 70°C), the module is well-suited for harsh industrial environments requiring high reliability and signal integrity.

The CC-PAIM01 is widely used in thermal processing, metallurgical operations, and pharmaceutical laboratories, where direct measurement of low-voltage signals is required. It is particularly suitable for applications involving thermocouples and precision instrumentation, eliminating the need for external signal conditioning and ensuring a more direct, accurate data path into the control system.
What is the benefit of the 1500V isolation in this module?
The high isolation rating prevents electrical noise, voltage spikes, and ground loop interference from affecting other channels or the control system, ensuring stable and accurate low-level signal measurement.
Does this module support standard 4–20 mA signals?
No, the CC-PAIM01 is designed exclusively for millivolt-level inputs (-100 mV to 100 mV). For standard current loop signals, modules such as CC-PAIN01 or CC-PAIH02 are recommended.
