8C-PAIMA1 Low Level Analog Input (Temperature) LLAI Module
The Low Level Analog Input (LLAI) Module, designated as 8C-PAIMA1, is designed to accommodate up to 16 channels of temperature inputs from both RTD (Resistance Temperature Detector) and TC (Thermocouple) sensors. This module offers robust features and precise temperature measurement capabilities suitable for industrial applications.
Notable Features:
- TC and RTD Operation: Supports both Thermocouple and RTD sensor inputs, providing flexibility in temperature sensing applications.
- Remote Cold Junction Compensation Capability: Ensures accurate temperature measurements by compensating for variations in ambient temperature.
- 1 Second PV Scanning with OTD Protection: Performs Open Thermocouple Detection (OTD) within the scanning cycle to validate temperature readings, enhancing reliability.
- Configurable OTD Protection: Allows configuration to handle Open Thermocouple Detection events, preventing erroneous control actions.
- Temperature Point Addition: Temperature points can be added in 16 point increments, facilitating scalability and customization of temperature monitoring.
