Industrial DRT2-HD16C Remote I/O Terminal Module

The Omron DRT2-HD16C is a 16‑channel remote I/O terminal that expands distributed digital input capability in industrial automation, communicating over DeviceNet networks. This unit provides 16 DC digital inputs rated for 24 VDC, drawing about 7 mA per point, with MIL connector or screw terminal connections (model dependent), mountable on a DIN rail and powered by an external 24 VDC supply. It uses photocoupler isolation and includes LED indicators for each input, delivering reliable status visibility in environments from 0°C to +55°C, suitable for control panels, conveyors, packaging machines, and production lines. Common replacements include DRT2-ID16, DRT2-MD16, and CJ1W-ID211, reflecting its role in scalable, networked PLC architectures that support flexible remote monitoring and expansion.
