SMT-ED12-R20-V3 IMO iSmart Intelligent Relay – V3 12VDC, HMI, 12 DI, 4AI

Why Choose the IMO SMT-ED12-R20-V3 iSmart Intelligent Relay?

The IMO SMT-ED12-R20-V3 is a compact 12 V DC iSmart V3 intelligent relay with integrated HMI, designed for machine automation, mobile equipment and low-voltage control applications. It combines programmable logic and local operator interaction with 12 DC input points and 8 relay outputs, providing 20 onboard I/O points in a compact controller.

As part of the IMO iSmart V3 programmable relay series, the SMT-ED12-R20-V3 incorporates 4 configurable 0–10 V analogue inputs within its 12-input configuration. These analogue-capable channels can also operate as digital inputs, allowing the controller to handle conventional switches and sensors alongside variable analogue signals from compatible transmitters.

Designed for 12 V DC systems, the SMT-ED12-R20-V3 provides 8 relay outputs rated at up to 8 A and 2 high-speed inputs operating at up to 1 kHz. Its integrated HMI and eight function keys support local monitoring and control, while Ladder Logic and Function Block Diagram programming provide flexible automation functionality.

Flexible 12 V Digital and Analogue Control

The IMO SMT-ED12-R20-V3 is particularly useful where automation must operate from a 12 V DC power source. Its 12 DC input points provide capacity for switches, contacts and compatible sensors, while four channels can accept 0–10 V analogue signals. The analogue channels can also be used as digital inputs, allowing the I/O configuration to be adapted to the requirements of the application.

Eight relay outputs provide switching for compatible AC or DC loads within their specified contact ratings, while two high-speed inputs extend the controller's capabilities to suitable pulse and counting tasks. Together with its integrated HMI, Ladder and FBD programming and expandable architecture, the SMT-ED12-R20-V3 can replace numerous conventional relays, timers and counters in compact automation systems.
