Low Level Analog (Temperature) Input – CC-PAIL51

Function: The Low Level IOP module supports up to 16 channels of temperature inputs, with each channel configurable for either Thermocouple (TC) or Resistance Temperature Device (RTD) inputs. Unlike the LLMUX (CC-PAIM01), this module supports 16 channels directly on the Series-C IOTA, eliminating the need for an external Process Manager FTA.

Notable Features:

• TC and RTD Operation: Each channel can be configured for either thermocouple or RTD inputs.
• Cold Junction Compensation: Ensures accurate temperature readings.
• 1 Second PV Scanning: Provides up-to-date temperature readings every second.
• OTD Protection: Offers configurable Open Thermocouple Detection protection.
