Commonly found in small and medium applications, the iSmart Programmable Relay from IMO is a highly cost-effective yet flexible controller that offers many of the functions found in a traditional PLCs and is an ideal controller for applications such as packaging and vending machines, conveyors, and automatic door systems.

iSmart is available as an AC or DC base module with a choice of input and output options as well as a selection of digital and relay expansion modules including support for temperature inputs and analogue inputs and outputs. iSmart is supplied with a built in HMI as standard or optional blind front module and is programmed using IMO's configuration software; available at no cost and is complete with a built-in simulation tool.
