Model Foxboro FBM201D Module Type Discrete Output (DO) - Dry Contact Relay Number of Channels 16 independent output channels. Output Type Form A (SPST) Dry Contact Relay. The module provides an isolated switch closure. Contact Rating 30 V DC / 0.5 A per channel. A common rating is 30 V DC, 2 A maximum per group of 8 channels. System Compatibility Foxboro I/A Series DCS. Must be installed in a compatible FBM fieldbase (e.g., FBM200 series). Update Rate Fast, typically on the order of milliseconds for state change execution. Power Supply Powered by the fieldbase (typically +5V and +24V from the power supply module). The field circuit must be powered by an external voltage source (within the contact rating). Isolation Channel-to-Channel: Yes, channels are isolated in groups. Channel-to-Bus: Optical and Relay isolation provides excellent protection for the system bus from field-side electrical transients and faults. Field Wiring Field wiring is terminated to a removable screw terminal block on the associated fieldbase. Diagnostics Includes internal diagnostics for module health (e.g., module failure, communication loss). LED Indicators Module status LEDs (e.g., OK, ACTIVE, FAIL) and per-channel status LEDs that show the commanded state (ON/OFF) of each output. Environmental Designed for industrial environments. Operating temperature typically 0 to 60°C (32 to 140°F).
