Why Choose the IMO SMT-ED12-R12-V3 iSmart Intelligent Relay?
The IMO SMT-ED12-R12-V3 is a compact 12 V DC iSmart V3 intelligent relay with integrated HMI, designed for industrial automation, mobile equipment, machinery and control panel applications. It combines programmable logic and local operator interaction with 8 DC input points and 4 relay outputs.
As part of the IMO iSmart V3 programmable relay series, the SMT-ED12-R12-V3 provides 6 dedicated digital inputs plus 2 inputs configurable for digital or 0–10 V analogue operation. Its analogue-capable inputs offer 12-bit resolution, allowing compatible variable-output sensors and transmitters to be incorporated directly into the control program.
Designed specifically for 12 V DC systems, the SMT-ED12-R12-V3 operates across a 10.2–13.8 V DC supply range and provides 4 relay outputs rated up to 8 A. It also includes 2 high-speed inputs operating at up to 1 kHz, an integrated text HMI with programmable function keys and support for both Ladder Logic and Function Block Diagram programming.

Programmable Control for 12 V DC Automation Systems
The IMO SMT-ED12-R12-V3 is specifically configured for applications using a 12 V DC control supply. This makes it particularly useful where a 24 V DC control supply is unavailable or where the automation system is powered directly from a nominal 12 V source. Its four relay outputs provide electrically switched outputs suitable for controlling compatible AC or DC loads within the specified contact ratings.
The combination of six dedicated digital inputs and two 0–10 V analogue-capable inputs allows the controller to monitor both discrete and variable signals. Together with its integrated HMI, high-speed inputs, PID capability, timers, counters and expandable architecture, the SMT-ED12-R12-V3 provides considerably more control functionality than a conventional relay-based system while retaining a compact footprint.
Typical Applications
- 12 V DC machine automation.
- Battery-powered control systems.
- Mobile and vehicle-mounted equipment.
- Pump, fan and auxiliary equipment control.
- 0–10 V sensor monitoring and control.
- Sequencing, timing and counting applications.
- Compact OEM machinery.
- Industrial and electrical control panels.
