Overview

The Patton Electronics FOI-2994-Z-ST is an 8-circuit control signal isolator designed to extend and isolate relay contacts over multimode ST fiber optics. This unit features latching Form C relay contacts on seven channels, with channel 8 configured as a non-latching output for momentary signal handling. The FOI-2994-Z-ST utilizes RX-only ST optical interfaces for signal reception, ensuring compatibility with standard multimode fiber deployments. Housed in a rugged, RF-shielded metal enclosure, this isolator delivers reliable performance in industrial environments where electrical noise and ground loops threaten signal integrity. Power options are sold separately, allowing integration with existing 12/24 VDC or 120/240 VAC power infrastructure. The device is part of Patton Electronics' FOI-2990 Series, which is recognized for robust signal management in automation, process control, and telecommunications applications. Key specifications include: 8 isolated channels with mixed latching/non-latching relay outputs, ST fiber interface (RX-only), RF-shielded enclosure for EMI immunity, and compatibility with Patton's FOI-2990 Series ecosystem. This isolator is ideal for extending control signals between PLCs, motor starters, and other industrial equipment while maintaining electrical isolation. The unit's Form C relay contacts provide both NO and NC switching paths for flexible circuit design, while the RX-only optics prevent back-reflection issues common in bidirectional fiber links. Channel 8's non-latching configuration supports applications requiring momentary signal transmission without retention.
