Hardware Specifications

Channel-to-Channel Isolation and Temperature Signal Acquisition

The 900A01-0102 module performs analog signal acquisition from multiple field instruments while maintaining electrical separation between input channels. The isolated channel architecture assists in minimizing the effects of ground loops and electrical noise originating from field wiring networks.

The module supports direct acquisition of voltage, current, resistance, RTD, and thermocouple inputs through a common hardware platform. For temperature measurement applications utilizing thermocouples and RTDs, correct sensor configuration and compensation parameters are required to maintain measurement accuracy throughout the operating range.

Multi-type input capability allows a single module to acquire process variables from diverse instrumentation sources without requiring dedicated hardware for each signal category.
