Product Short Description
- Product Name: Foxboro FBM218 8-Channel HART Communication Redundant Analog Output Module
- Product Introduction: A redundant HART-enabled analog output module providing 8 channels of 4–20 mA control signals with superimposed HART communication. It supports module-level redundancy for high availability, enabling reliable closed-loop control of HART-enabled valves and actuators in critical processes.
Description
- Technical Specifications:
- Channels: 8 galvanically isolated analog output channels (4–20 mA + HART).
- Output Signal: 4–20 mA DC; 750 Ω max load; ±0.05% of span accuracy.
- HART Communication: Supports HART Versions 5, 6, 7; 1200 baud; 2 messages/sec; parity/CRC error checking.
- Redundancy: Module pair redundancy (master/tracker) with shared termination assembly.
- Isolation: 600 V AC galvanic isolation between channels and ground.
- Power: 10–30 V DC; ≤2.5 W power consumption.
- Environment: Operating -20°C to +70°C; Class G3 harsh environment rated.
- Features:
- 8 isolated 4–20 mA outputs for control valves, actuators, and positioners.
- Bi-directional HART communication for device configuration, diagnostics, and asset management.
- Redundant module operation for high availability in critical processes.
- Per-channel isolation eliminates ground loops and crosstalk.
- LED indicators for module status, redundancy state, and channel activity.
- Applications: Critical process control loops (chemical, oil/gas, power, pharmaceuticals) requiring high availability; control of HART-enabled control valves, actuators, and smart positioners in redundant DCS configurations.
