CMC-99/141 PID Programmable Controller


The CMC-99 is a compact multi-channel indicator with a colour touchscreen 3.5" display. The screen is backlit and the user can select the brightness and contrast via the simple to use navigation menu. The system is based on a LINUX operating system, which is ideal for applications where simultaneous measurement and control is required.

The device has built-in RS485 interface with Modbus RTU protocol as the standard communications. This makes interfacing to the device, programming via software and using as a slave or master very easy to accomplish.

There are 48 analogue input channels, 16 relay outputs and 7 analogue outputs which make this a very flexible indicator and brings in an element of control via the outputs.

The onboard 24V dc sensor power supply makes installation simple to power external sensors.

Each and every channel can be used to operate on a PID control function via the menu navigation and the onboard relays and analogue outputs. This offers the user the chance to not only indicate but also control a process and the sensors with that process.
