Controller 2 lines: 10I, 6OP, 2 AI, M91-2-R2C

Unitronics M90/91 series controllers are compact devices combining the functions of a PLC controller and a user-friendly HMI panel. The M91-2-R2C model stands out for its versatility and applicability in various automation applications. Thanks to the built-in two-line display and keys, it enables direct interaction with the process and quick changes to the program.

This specific model offers 10 digital inputs, including 3 high-speed (5kHz) – which is particularly useful for handling fast signals from sensors or encoders. It also has 2 analog inputs and 6 relay outputs, providing flexibility in controlling various devices. The device is powered by 12/24VDC, which simplifies integration with existing infrastructure.

The built-in RS232/485 communication port (user-configurable) allows for easy integration of the controller with other devices and SCADA systems, using the Modbus Master/Slave communication standard. Program memory with a capacity of 36KB and the ability to support up to 256 coils, 256 registers, and 64 timers allow for the implementation of complex control algorithms. A battery ensures long-term memory operation – up to 7 years at a temperature of 25°C.

The controller's design is intended for demanding industrial conditions – the IP65/NEM4X (front) protection rating guarantees resistance to dust and moisture. A two-line LCD display (STN LCD, 2 lines of 16 characters) and 15 buttons provide intuitive operation and easy access to process parameters.

The M91-2-R2C controller is a solid solution for installers looking for a reliable and compact control system, as well as for end-users who need a user-friendly device for process automation. Its modular design allows for adaptation to specific application requirements, and ease of programming ensures quick commissioning and minimizes service costs.
