Precision Signal Acquisition for Process Monitoring
The Schneider ASB351001 analog input module provides eight isolated channels for acquiring 4-20 mA current signals from field sensors. This module accepts standard analog signals from pressure transmitters, temperature sensors, and flow meters in industrial processes. Each channel includes a 12-bit resolution analog-to-digital converter, ensuring accurate measurement with 0.1% precision. The module offers a 24V DC loop power supply for two-wire transmitters, simplifying field wiring. It also features programmable input filtering to reduce electrical noise and signal fluctuations. Moreover, the module provides per-channel diagnostics for detecting open-circuit or short-circuit conditions.
