8- Channels Analog Input Module
Product model:UW7212

UW7212 8 Channels Analog Input Module realizes 8-channels 010mA020mA420mAanalog signal input, with functions featuring signal type selection, programmable amplification, data conversion, error detection, digital filtering, temperature compensation, linearity correction, industrial transforming, etc.

  • Intelligent conditioning, supports 8-channels 0~10mA、0~20mA、4~20mA analog signal input, software selects signal types, full-scale high accuracy;

On-process self-diagnostic, automatic ambience-temperature compensation and zero & gain correction; No further calibration or maintenance necessity; automatic off-line detection;

  • Complete isolation between Modules and system; PhotoMos relays switching channels; Complete isolation between channels so that precludes external disturbance;

  • Low-power-consumption designed Modules with expanded working temperature range;

  • Equipped with industrial wiring terminal sets, cancelled accessories such as system rack, bottom support, terminal blocks and wiring cables for easier maintenance;

Internal optional input voting algorithm, input self-diagnosis and error report mechanism; Optional Non-Redundant/Redundant configurations and configuration strategies based on single Module.
