New multi-channel controller with touch-screen display

According to Impress Sensors & Systems, the CMC-99 provides an extensive variety of input and output combinations to suit individual customer requirements. The three card slots on the reverse of the controller each comprise 16 I/O pin options. For example, up to 48 analogue current or voltage inputs could be used; up to 16 relay/SSR outputs; 24 thermocouple inputs; or 12 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 claimed to be a low-cost device compared with existing alternatives on the market and is suitable 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. The CMC-99 can also act as a PID process controller, providing control for process temperature and pressure control.

Measuring just 96mm x 96mm x 100mm, the controller is very compact. It has a 3.5-inch backlit colour TFT display and uses the Linux operating system, with touch-screen menu navigation for ease of use. A USB interface is provided on the front of the device, enabling software programs to be uploaded or downloaded quickly and easily via a USB memory stick. The CMC-99 also comes with a number of communications interfaces, including two RS485 ports, two RS232 ports, a second USB host and an Ethernet connection, allowing the controller to integrate easily with customers' existing process control networks and fieldbuses.

The controller is available in two power supply versions, 230V or 24V AC/DC. An auxiliary 24V DC/200mA supply output on the back enables external sensors and actuators to be connected and powered by the controller.

Impress Sensors & Systems says the CMC-99's integral software provides 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.

The CMC-99 is also available with a transparent, lockable door that is sealed to IP42. An IP65 version is supplied with an additional fitted moulded frame.
