Foxboro FBM207C 16-Channel 48 V DC Contact Sense Input Module

Product Short Description

Product Name: Foxboro FBM207C 16-Channel 48 V DC Contact Sense Input Module
Product Introduction: A high-voltage variant of the FBM207 series, offering 16 channels of 48 V DC contact sensing for industrial DCS. It provides enhanced noise immunity and is optimized for high-voltage discrete input applications in harsh environments.
Technical Specifications:
- Channels: 16 galvanically isolated contact sense inputs.

- Input: 48 V DC ±15% open-circuit voltage; 3.2 mA typical short-circuit current.
- Logic Levels: On-state (Logic 1): ≤1 kΩ; Off-state (Logic 0): ≥100 kΩ.
- Pulse Count: 0–250 Hz with no missing pulses.
- Filter/Debounce: Configurable (None, 4, 8, 16, 32 ms).
- Isolation: 600 V AC group isolation between channels and ground.
- Environment: Operating -40°C to +85°C; storage -40°C to +85°C.
- Physical: Extruded aluminum housing; 102 mm × 45 mm × 104 mm; ~284 g.
Features:
- 48 V DC contact sensing for high-voltage industrial discrete inputs.
- 16 independent, isolated channels for fail-safe monitoring.
- Configurable input filtering for noise rejection and contact debouncing.
- LED status indicators for module health and each input channel.
- Compatible with Foxboro I/A Series redundant fieldbus and termination assemblies.
Applications: Heavy industry, manufacturing, and process control systems requiring 48 V DC discrete input monitoring, such as high-voltage relay contacts, motor control centers, and safety interlocks.
