Overview
Square D 3020-IOM-44 is a PowerLogic I/O module designed for industrial automation and circuit monitor integration. Manufactured by Schneider Electric (formerly Square D), the 3020-IOM-44 has four status inputs, one KYZ pulse output, and three Form-C relays output. It allows MicroLogic full-function circuit breaker units to communicate and be networked within a PowerLogic network. This used unit provides proven reliability for legacy PowerLogic 3020 systems requiring I/O expansion.
