SMT-EA-R20-V3 IMO iSmart Intelligent Relay – V3 110-240VAC, HMI, 12 DI (AC)

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

The IMO SMT-EA-R20-V3 is a compact iSmart V3 intelligent relay with integrated HMI, designed for industrial automation, machinery and control panel applications. It combines programmable control logic with 12 AC digital inputs and 8 relay outputs, providing substantial onboard I/O for sequencing, switching and machine control.

As part of the IMO iSmart V3 programmable relay series, the SMT-EA-R20-V3 operates from a 100–240 V AC supply and provides eight relay outputs rated at up to 8 A. Its integrated text HMI and programmable function keys provide convenient local monitoring and operator control without requiring a separate display for straightforward applications.

The SMT-EA-R20-V3 supports powerful control logic using both Ladder Logic and Function Block Diagram (FBD) programming. The iSmart V3 platform also provides PID control, maths functions, retentive data registers and expansion capability, making this model a flexible solution for applications that require more functionality than conventional relays, timers and counters can provide.

Programmable Control with an Integrated Operator Interface

The IMO SMT-EA-R20-V3 combines programmable logic and local operator interaction within a single compact controller. Its 12 AC inputs can receive signals from switches, contacts and compatible AC control devices, while eight relay outputs provide switching capability for contactors, indicators, solenoids and other suitable control loads.

The integrated HMI allows operating information and control functions to be made available directly at the unit, reducing the need for separate panel components in suitable applications. Ladder Logic and Function Block Diagram programming, together with timers, counters, PID and maths functions, enable the SMT-EA-R20-V3 to replace numerous conventional control components while remaining expandable when additional I/O is required.

• Industrial machine automation.
• Pump, fan and motor control systems.
• Conveyor and material handling equipment.
• Lighting and building control systems.
• Packaging and production machinery.
• Sequencing, timing and counting applications.
• Local machine monitoring and operator control.
