Potter & Brumfield IAC-15 Digital Input Relay Module

Potter & Brumfield IAC-15 Digital Input Relay Module is an industrial-control interface that converts a digital input into a relay actuation in 120 VAC systems. The device operates at 120 VAC with an input tolerance of 90–140 VAC and is associated with the IAC-15 and IAC-5 model identifiers. Designed for installation in control panels and automation circuits, this module serves as a compact bridge between low-level digital signals and a relay coil, enabling simple signaling, interlock, or control tasks in electrical control architectures. As a Potter & Brumfield component, it reflects the company’s legacy of reliable relay technology and is suitable for integration wherever a digital input must drive a relay in AC-powered environments. Identified within the Potter & Brumfield IAC family as the IAC-15 (with related IAC-5 variants), the module functions as a dedicated digital input interface for triggering a relay and is commonly mounted in panel-mounted control setups alongside other control devices to streamline wiring and signal routing.
