Product Description
The Automation Direct PX-549 is a Protos X discrete combination I/O terminal module providing eight 24VDC sinking (NPN) inputs and eight 24VDC sourcing (PNP) outputs at 0.5A per point. The module features reverse polarity protection, LED status indicators for all I/O points, and spring clamp wiring terminals. It supports Modbus RTU, Modbus TCP, and EtherNet/IP communication standards. It is designed for use exclusively within the Protos X Field I/O system and mounts on standard DIN rail.
