What this I/O module does in the rack
The DRT2-ID16TA-1 is a 16-point digital input module from Omron's DRT2 series, used to bring discrete field signals (limit switches, proximity sensors, pushbuttons) back to a PLC backplane. It sits in the PLC I/O & Expansion Modules category, meaning it expands the I/O count of an existing Omron PLC rack rather than serving as a standalone controller.
