FBM218 high-performance discrete output module

The FBM218 is a high-performance discrete output module developed by Foxboro for its I/A Series Distributed Control System (DCS). It is designed to convert digital control signals from the DCS into discrete output signals to drive field devices such as relays, solenoid valves, and indicator lights, ensuring reliable control of industrial processes. Below is its detailed information:

1. Core Technical Specifications

Parameter	Details
Output Channels	16 independent discrete output channels, divided into 4 isolation groups (4 channels per group) for enhanced anti-interference.
Supported Output Signals	DC voltage signals: 15–60V DC (typical), with configurable "on" and "off" states.Relay output compatibility: Supports driving external relays for AC/DC loads (e.g., 120V AC, 240V AC).
Load Capacity	Maximum current per channel: 2.5A (continuous); peak current: 5A (short-duration), suitable for most industrial actuators.
Response Time	≤10ms (from digital command to output state change), ensuring timely control actions for fast-response processes.
Power Supply	24V DC ±10% (power consumption ≤8W, compatible with I/A Series rack power modules like P0916JP).
Isolation Rating	Group-to-group isolation: ≥600V AC (1 minute).Module-to-backplane isolation: ≥2500V AC (1 minute), preventing ground loops and electromagnetic interference (EMI).
