The CMC-99 controller from Impress Sensors & Systems Ltd provides an incredible variety of input and output combinations to suit individual customer requirements. The three card slots on the reverse of the controller each comprise 16 x I/O pin options, which enable the user to choose any combination of inputs and outputs to suit the application. For example, up to 48 x analogue current or voltage inputs could be used; up to 16 x relay/SSR outputs; 24 x thermocouple inputs; or 12 x RTD inputs; or a combination of these. The unit also incorporates a 24V DC digital input, enabling relays and triggers to be set up.
The CMC-99 is low cost compared to existing alternatives on the market and is ideal for a wide range of process applications, including centralised temperature measurement and control; multi-zone heating control; intermediate pumping station control; spraying and heating control for greenhouses; control of industrial furnaces and incinerators; and for engine test cell measurements.
Measuring just 96mm x 96mm x 100mm, the controller housing is very compact, which means the unit can be installed in restricted spaces. The controller has a 3.5-inch backlit colour TFT display and is based on the Linux operating system, with touch-screen menu navigation, offering ease of use and familiarity to the operator. A USB interface is provided on the front of the device, enabling the user to upload or download software programs quickly and easily via a USB memory stick.
The controller is available in two power supply versions, 230V or 24V AC/DC. An auxiliary 24V DC/200mA supply output on the back of the unit enables external sensors and actuators to be connected and powered by the controller. The CMC-99 can also act as a PID process controller, providing a reliable control loop feedback mechanism for a variety of process temperature and pressure control applications.
The CMC-99 also comes with a number of communications interfaces, including two RS485 ports, two RS232, a second USB Host and an Ethernet connection, allowing the controller to integrate easily with the customer’s existing process control networks and fieldbuses.
The CMC-99’s integral software provides the user with archiving, printing and visualisation options. A variety of visual presentation display options for recorded measurements are available, including numerical display, bar graph or needle gauge display.
