Why Choose the Unitronics M91-2-T2C Micro PLC with Integrated HMI?
The Unitronics M91-2-T2C is a versatile Micro PLC with integrated text-based HMI, designed for industrial automation applications that require digital control, analogue signal processing and high-speed transistor outputs within a single compact controller. As part of the reliable Unitronics M91 series, it combines PLC functionality, an operator interface and onboard I/O to reduce installation complexity, minimise panel space and lower overall automation costs.
Featuring a built-in 2-line, 16-character LCD display and a durable 15-key membrane keypad, the M91-2-T2C enables operators to monitor machine status, adjust process parameters and access diagnostics directly from the controller. This integrated design eliminates the need for a separate HMI whilst maintaining a simple and cost-effective automation solution.
With 10 digital inputs, 2 analogue/digital inputs and 12 transistor outputs, plus CANbus networking and high-speed counter functionality, the M91-2-T2C is ideally suited to OEM machinery, material handling systems, packaging equipment and industrial process control applications.
