Why Choose the IMO SMT-2AO iSmart Analogue Output Expansion Module?
The IMO SMT-2AO is a compact two-channel analogue output expansion module designed for the IMO iSmart programmable relay platform. It expands a compatible iSmart controller with two configurable analogue outputs, enabling the control of equipment requiring variable voltage or current reference signals.
As part of the IMO iSmart expansion module range, the SMT-2AO operates from a 24 V DC supply and supports analogue voltage and current output modes. Each channel can be configured for applications requiring a 0–10 V voltage signal or an analogue current signal, making the module suitable for proportional control of drives, valves, actuators and other industrial equipment.
The SMT-2AO provides two analogue output channels and is designed for straightforward integration with compatible iSmart controllers. Its compact DIN rail-mounted format makes it particularly suitable for industrial control panels where additional analogue control capability is required without installing a separate PLC or standalone analogue controller.

Flexible Analogue Control for iSmart Automation Systems
Analogue outputs allow an automation controller to provide continuously variable command signals rather than simple on/off switching. The IMO SMT-2AO extends compatible iSmart systems with two such channels, allowing the programmable relay to control equipment such as variable speed drives, proportional valves and analogue actuators according to the application's control logic.
The module's selectable voltage and current output capability makes it useful across machine automation and process control installations. Integration into the iSmart expansion architecture also allows analogue control to be added while retaining the compact footprint and straightforward programming associated with the iSmart platform.
