Omron ZEN-20C1DR-D-V2 Analog Programmable Relay

The Omron ZEN-20C1DR-D-V2 Analog Programmable Relay (MPN ZEN-20C1DR-D-V2) is a compact Smart Relay from the ZEN V2 series designed for logic control and small-scale automation in control panels, HVAC systems, lighting control, and small machinery. It provides 20 total I/O points—12 digital inputs and 8 relay outputs—powered by 24 VDC, with a built-in LCD display and keypad for ladder-logic programming and non-volatile EEPROM memory to retain programs. Mounting options include DIN rail or panel mounting, and optional communication modules expand connectivity, while an operating temperature range of 0°C to 55°C supports reliability in commercial and industrial environments. Key applications include control panels, building automation, pump and conveyor control, and equipment monitoring where a compact PLC alternative is needed.
