Design and Performance
Universal Signal Acquisition in One Module
Supports voltage, current, thermocouple, RTD, and resistance measurement across a single module, letting engineers standardize on one analog input type for mixed sensor applications instead of stocking separate modules per signal type.
High-Resolution, Precise Measurement
16-bit resolution with 0.3% accuracy delivers precise readings across all supported measurement types, suited for demanding process monitoring and control applications where measurement precision matters.
Flexible Temperature Measurement
4 of the 8 channels support direct RTD and PTC connection alongside thermocouple inputs on all channels, giving broad flexibility for temperature monitoring across different sensor technologies within the same station.
Complete, Ready-to-Wire Delivery
Ships with the infeed element, shield bracket, and shield terminal included, streamlining installation and ensuring proper shielding for accurate analog signal transmission from the start.
Responsive Diagnostics
Diagnostic function and hardware interrupt support give fast visibility into wire-break, overrange, and underrange conditions, helping identify and resolve sensor or wiring issues quickly.
