FBM223 digital input/output (I/O) mixed module

The FBM223 is a digital input/output (I/O) mixed module developed by Foxboro for its I/A Series Distributed Control System (DCS). It integrates digital input and output functions in a single module, enabling efficient acquisition of field switching signals and execution of control commands—ideal for industrial scenarios requiring compact and integrated I/O solutions. Below is its detailed information:

1. Core Specifications

I/O Channel Configuration: 16 independent digital input channels + 8 independent digital output channels (fixed configuration for balanced signal acquisition and control).
Supported Input Signals:
- Dry contact signals (normally open/normally closed)
- Low-voltage DC signals (24VDC, "on" threshold: 18–30VDC, "off" threshold: 0–5VDC)
Supported Output Signals:
- Relay outputs (normally open contacts, suitable for AC/DC loads)
- Solid-state outputs (24VDC, sink/source configurable, for high-speed DC load switching)
Input Response Time: ≤1ms (captures transient signals like emergency stop triggers to ensure timely control).
Output Load Capacity:
- Relay outputs: 250V AC/30V DC, 5A (resistive load)
- Solid-state outputs: 24VDC, 1A per channel
Environmental Ratings:
- Operating temperature: -40°C to 70°C
- Storage temperature: -40°C to 85°C
- Protection rating: IP20 (module itself; system-level protection depends on cabinet design)
