Why Choose the IMO SMT-ED-T12-V3 iSmart Intelligent Relay?
The IMO SMT-ED-T12-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 logic, local operator interaction and flexible I/O, with 6 dedicated digital inputs, 2 analogue-capable inputs and 4 transistor outputs.
As part of the IMO iSmart V3 programmable relay series, the SMT-ED-T12-V3 provides 2 configurable 0–10 V analogue inputs that can also be used as digital inputs, giving a total of eight DC input points when both channels are used digitally. Its solid-state transistor outputs are rated at 0.5 A, providing fast, wear-free switching for compatible DC loads.
The SMT-ED-T12-V3 operates from a 24 V DC supply and includes an integrated text HMI with programmable function keys for local monitoring and control. It also provides 2 PWM outputs operating at up to 0.5 kHz, while Ladder Logic, Function Block Diagram, PID, maths and retentive data functions support a wide range of compact automation tasks.

Transistor and PWM Outputs for Flexible DC Control
Unlike relay-output iSmart variants, the IMO SMT-ED-T12-V3 uses four 0.5 A transistor outputs. Solid-state transistor switching is particularly useful for compatible DC loads where frequent or rapid switching is required, as there are no mechanical output contacts to wear during normal operation.
Two outputs also support PWM operation at up to 0.5 kHz, extending the controller's capabilities beyond conventional on/off switching. Combined with two 0–10 V analogue-capable inputs, an integrated HMI and programmable logic functions, the SMT-ED-T12-V3 provides a versatile platform for compact machine and process automation.
