Foxboro P0916NB Isolated Output Module

The Foxboro P0916NB, also cataloged as the P0916NB Isolated Output Module, operates as a dedicated hardware component for discrete signal processing within Foxboro I/A Series DCS platforms. It executes electrical isolation and output switching across 8 dedicated channel pathways to drive field actuators, relays, and discrete control elements from the backplane bus.

4-20 mA HART Loop Protocol & Channel Isolation

The P0916NB incorporates continuous channel-to-channel isolation barriers that decouple individual field wiring circuits from backplane logic processing. This structural isolation prevents ground loops and high-voltage field transients from damaging system logic boards or disrupting adjacent analog signals, such as 4-20 mA HART loop protocol lines running through shared cable ducts. Internal galvanic separation ensures signal purity, allowing digital control outputs to operate stably alongside sensitive analog inputs that utilize cold junction compensation (CJC) and high-density signal conversion circuits.

Frequently Asked Questions

Q: What are the primary power requirements for the P0916NB module?

A: The module operates on a nominal supply voltage of 24 VDC with redundant line support, drawing a maximum power load of 8.5 W.

Q: How does channel-to-channel isolation protect the system architecture?

A: Galvanic isolation barriers physically separate each of the 8 output channels, preventing common-mode voltage spikes and field ground loops from propagating across the backplane.

Q: Can terminal wiring remain attached during module field servicing?

A: The assembly supports quick-disconnect wiring blocks, allowing field wiring to remain terminated while replacing the primary electronic module chassis.

Field Installation Guidelines

Mount the P0916NB module onto the designated enclosure DIN rail or mounting rack frame, securing all chassis retention hardware. Connect primary and redundant 24 VDC power lines to the corresponding input terminals using rated wire gauges. Terminate field device conductors at the screw or spring-clamp blocks, ensuring signal pairs remain isolated from high-voltage AC conductors. Bond field cable drain wires directly to the cabinet ground bus bar to maintain shielding efficiency against external electromagnetic interference.
