Why Choose the IMO SMT-ED-T20-V3 iSmart Intelligent Relay?
The IMO SMT-ED-T20-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, providing 12 DC input points and 8 transistor outputs within a single expandable controller.
As part of the IMO iSmart V3 programmable relay series, the SMT-ED-T20-V3 incorporates 4 configurable 0–10 V analogue inputs within its 12-input configuration. The analogue-capable channels can also be used as digital inputs, enabling the controller to handle both conventional switching devices and variable analogue signals from compatible sensors and transmitters.
Operating from a 24 V DC supply, the SMT-ED-T20-V3 provides 8 transistor outputs rated at 0.5 A and includes 2 PWM outputs operating at up to 0.5 kHz. Its integrated HMI provides convenient local monitoring and control, while Ladder Logic, Function Block Diagram, PID, maths and retentive data functions support demanding compact automation applications.

Transistor and PWM Control for High-Cycle Automation
The IMO SMT-ED-T20-V3 uses 8 solid-state transistor outputs rated at 0.5 A rather than mechanical relay outputs. This makes the controller particularly useful for compatible DC applications involving frequent switching, as transistor outputs provide rapid operation without the mechanical contact wear associated with conventional relay outputs.
Two outputs also provide PWM operation at up to 0.5 kHz, allowing compatible equipment to be controlled using pulse-width modulation. Combined with four 0–10 V analogue-capable inputs, an integrated HMI and the extensive programming functions of the iSmart V3 platform, the SMT-ED-T20-V3 provides a versatile solution for compact machine and process automation.
