Schneider Electric AS-B351-001 Programmable Logic Controller Module

Schneider Electric AS-B351-001 is an eight-input discrete input module for Modicon PLC systems. It accepts 115 VAC field signals and provides eight digital input channels to the host controller, enabling direct connection of common 115 VAC sensors and switches to a Schneider Electric automation rack. This 115 VAC input module is part of Schneider Electric’s Modicon lineage (Gould/Schneider automation heritage) and is typically deployed in legacy Modicon backplane configurations where eight concurrent input signals are required. The AS-B351-001 variant identifies the 115 VAC, eight-input option within the 300-series I/O modules, delivering straightforward expansion of PLC input capability for industrial control applications that rely on legacy Schneider Electric hardware.
