SMT-BD-R12-V3 IMO iSmart Intelligent Relay – V3 24VDC, Blind, 6 DI, 2AI

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

The IMO SMT-BD-R12-V3 is a compact 24 V DC iSmart V3 intelligent relay designed for small industrial automation, machinery and control panel applications. It combines programmable control logic with digital and analogue input capability, providing a flexible alternative to conventional hard-wired relay, timer and counter circuits.

As part of the IMO iSmart V3 programmable relay series, the SMT-BD-R12-V3 provides 8 DC input points, including 2 configurable 0–10 V analogue inputs, together with 4 relay outputs. The two analogue channels can also be used as digital inputs, allowing the controller to accommodate both switching signals and variable process signals within a compact control system.

Operating from a 24 V DC supply, the SMT-BD-R12-V3 supports powerful control logic using Ladder Logic and Function Block Diagram (FBD) programming. It is a blind base unit without an integral HMI display and includes two high-speed inputs capable of operation at up to 1 kHz, making it suitable for compact machine control, monitoring and sequencing applications.

Flexible Digital and Analogue Control for Compact Automation

Intelligent relays combine programmable logic with industrial input and output interfaces, allowing control functions that would otherwise require multiple relays, timers and counters to be implemented within a single compact controller. The IMO SMT-BD-R12-V3 extends this capability with analogue inputs, allowing variable signals such as sensor outputs and control references to be incorporated directly into the application logic.

The two analogue-capable inputs can alternatively operate as digital inputs, giving designers flexibility when configuring the controller for a particular machine. High-speed inputs, PID control, maths functions and compatible expansion modules further extend the iSmart V3 platform for applications requiring more than basic on/off sequencing.

Typical Applications

• Small industrial machinery and automation systems.
• Pump, fan and motor control.
• Sensor monitoring using 0–10 V signals.
• Conveyor and material handling equipment.
• HVAC and building automation systems.
• Packaging and production machinery.
• Timer, counter and sequencing applications.
• OEM equipment and electrical control panels.
