Control, Measurement and Data Logging for Customized Slow Control

The Control, Measurement and Data Logging system (CML) is designed to add remote control and monitoring functionality to electronic systems. Analog measurement is done with a fast & high precision 12 bit AD converter.  The 18 analog input channels are configured to measure 8 voltages, 6 temperature probes, and 4 general purpose analog inputs.

The integrated supervision system compares all measured voltages with a minimum and maximum value and temperatures with a maximum value.  Exceeding the supervision threshold can switch off the system.

Fan speed measurement and speed control of up to 6 fans is provided.  The fan supply voltage is generated on board, so no special fans with PWM input are required.  Up to 3 fan groups can be regulated individually.

If the CML is supplied by an external power source, it is possible to switch the main system power supply on or off with the on/off switch or via network.

All necessary functions are implemented on a small (86mm x 110mm) board.  The system connections are provided on a 2mm high density connector.  The CML00 can be outfitted with an auxiliary power supply.
