SMT-ED-R12-V3 IMO iSmart Intelligent Relay – V3 24VDC, HMI, 8 DC in, 2A/D in

Why Choose the IMO SMT-ED-R12-V3 iSmart Intelligent Relay?

The IMO SMT-ED-R12-V3 is a compact 24 V DC iSmart V3 intelligent relay with integrated HMI, designed for industrial automation, machinery and control panel applications. It combines programmable control logic with digital and analogue input capability, providing a practical all-in-one controller for sequencing, monitoring and machine control.

As part of the IMO iSmart V3 programmable relay series, the SMT-ED-R12-V3 provides 6 dedicated DC digital inputs plus 2 inputs configurable for digital or 0–10 V analogue operation, together with 4 relay outputs rated up to 8 A. This flexible input arrangement enables both conventional switches and sensors and variable analogue signals to be incorporated into the same compact control system.

The SMT-ED-R12-V3 operates from a 24 V DC supply and includes an integrated text HMI with programmable function keys for local monitoring and operator interaction. Two inputs also support high-speed operation at up to 1 kHz, while Ladder Logic, Function Block Diagram, PID, maths and retentive data functions provide extensive programming flexibility.

Integrated HMI and Analogue Monitoring for Compact Automation

The IMO SMT-ED-R12-V3 combines programmable logic, local operator interaction and analogue monitoring within one compact controller. Six dedicated DC inputs provide connections for conventional switches and sensors, while two additional channels can accept 0–10 V analogue signals or operate as digital inputs. This allows compatible pressure, level, position and other analogue sensors to be incorporated directly into the control logic.

Its integrated HMI provides local information and operator controls without requiring a separate display in straightforward applications. Combined with high-speed inputs, relay outputs, timers, counters, PID functionality and expandable I/O, the SMT-ED-R12-V3 provides a flexible alternative to conventional hard-wired relay control for compact industrial automation systems.

Typical Applications

• Industrial machine automation.
• Pump, fan and motor control systems.
• 0–10 V sensor monitoring.
• Conveyor and material handling equipment.
• HVAC and building automation systems.
• Packaging and production machinery.
• High-speed pulse and counting applications.
• OEM machinery and electrical control panels.
