Foxboro FBM242 P0916TA Discrete Output Interface Module

Multi-channel Current Monitoring: Equipped with 8-channel analog inputs, supporting 0-20mA/4-20mA current signal monitoring. It can collect multi-channel current data simultaneously, suitable for accessing sensor signals such as flow, pressure, and liquid level in industrial fields.

High Precision and Anti-interference: Adopts isolated design with strong electromagnetic interference resistance, ensuring stable and accurate signal transmission. The measurement accuracy can reach ±0.1% FS.

Real-time Data Processing: Built-in signal conditioning and A/D conversion functions convert analog current signals into digital quantities in real time, facilitating reading and control by the host computer system.

Industrial-grade Protection: Fully sealed structure with protection level meeting industrial environment requirements (e.g., dustproof and splash-proof). It adapts to the operating temperature range of -10°C to 60°C, suitable for harsh scenarios such as power plants, chemical, and petroleum industries.

Flexible Communication Interface: Supports communication protocols like Modbus RTU, enabling seamless integration with Foxboro DCS systems or third-party controllers to achieve remote data transmission and monitoring.

Signal Acquisition: Receives 0-20mA/4-20mA current signals (e.g., from pressure transmitters, flowmeters) through 8 independent channels, with each channel featuring signal isolation to avoid cross-channel interference.

Signal Conditioning and Conversion:

Data Processing and Storage: The internal processor of the module calibrates (e.g., zero/full scale calibration) and linearizes digital signals, and stores configuration parameters (e.g., range, alarm thresholds).

Communication Transmission: Transmits processed data to FCP 270 controllers or host computers via Modbus RTU protocol. It also supports LED indicators (PWR, COM, ALM) to display working status and communication conditions in real time.
