Omron ZEN-20C1DT-D-V2 Programmable Relay Controller

The Omron ZEN-20C1DT-D-V2 is a compact PLC CPU unit from Omron’s ZEN V2 series, built to handle simple control logic in small-scale automation such as control panels, machinery, and building automation. It provides 12 inputs (10 digital and 2 analog) and 8 solid-state transistor outputs, powered by 10.8–28.8 V DC, with ladder-logic programming via PC or front panel and a built-in LCD display with operation buttons. RS-485 communication is supported (model dependent), and the unit mounts on DIN rail or panel and supports up to 3 expansion I/O modules. The operating range is 0°C to 55°C with IP20 protection, positioning it for machine control, lighting, HVAC automation, and other compact production equipment. Part of Omron’s ZEN V2 family, the ZEN-20C1DT-D-V2 is commonly used for replacement or retrofit in small automation control solutions.
