Pilot Circuit Converters

This document describes the K-Series Pilot Circuit Converters (K508, K604, and K716), which interface 120 VAC electrical equipment—such as pilot contacts, motor starters, and solenoid-operated valves—with digital logic systems.

Key features include:

• Module Functions: The K508 acts as a pilot contact input, the K604 serves as an isolated AC switch, and the K716 functions as a terminal block.
• Safety and Reliability: The K508 features contact bounce suppression and glow-lamp indicators, while AC switching elements are protected by fast fuses. Interlock switches are available to disable the K604.
• Physical Design: The modules use a 2-foot ribbon cable, allowing the terminal block to be mounted on the rear of a NEMA enclosure while the digital system remains accessible on the door.
• Maintenance: The K716 terminal block uses clamping-type terminals for 14-gauge wires and features a quick-disconnect system to minimize downtime and facilitate off-site system testing.

The document also provides technical specifications, mounting dimensions for the K716, and unit pricing.
