Product Performance
Signal Acquisition Performance: Equipped with 4 independent configurable RTD input channels, supports flexible access of 3-wire and 4-wire RTDs, 16-bit high-resolution analog-to-digital conversion, with excellent measurement accuracy. It can accurately collect temperature and resistance signals of various RTDs, supports three output units: Celsius, Fahrenheit and resistance value, adapting to different monitoring needs, with stable and distortion-free data collection.
Calibration and Diagnosis Performance: Supports power-on automatic calibration and periodic automatic calibration, which can effectively compensate for measurement errors caused by ambient temperature changes. Built-in full-function fault diagnosis mechanism, real-time monitoring of open wire, short circuit, over-range and under-range faults, triggering corresponding alarms synchronously, with accurate fault location for quick abnormality troubleshooting.
Isolation and Anti-interference Performance: Has electrical isolation capability between input and logic circuit, as well as excellent common-mode rejection and normal-mode rejection performance. It can effectively shield industrial field electromagnetic interference and surge signals, eliminate signal crosstalk between channels, ensure stable and accurate measurement data, and protect the back-end main control equipment from external interference.
Compatibility Performance: Custom-developed for GE VersaMax series PLC system, perfectly compatible with all main control units, network interface units and standard racks of this series. Supports independent channel start-stop configuration, no external auxiliary power supply required, module comes with excitation current and can automatically match various RTD types, with convenient field deployment.
Environmental Adaptability Performance: Adopts industrial-grade components and standardized manufacturing process, adapts to conventional temperature and humidity environment in industrial field, resistant to dust and vibration, can operate continuously and stably for a long time without frequent faults, meets the all-weather working needs of industrial automation sites, and adapts to various harsh but non-extreme industrial working conditions.
Operation and Maintenance Convenience Performance: Modular compact structure design, easy installation and wiring, with built-in status indicator to visually view module operation and fault status. Supports software remote configuration and diagnosis, simplifies daily operation and maintenance and fault troubleshooting process, reduces operation and maintenance costs, and supports online replacement and system expansion.
