C-mac module type LC24 is a loop-powered double isolation amplifier, which means the current consumption is proportional with the input current
The unit is suitable in connection with process monitoring systems, if you want to separate several monitoring signals with diffenrent potentials, before they are being connected to PLC-controls or the like.
The two isolation amplifiers are totally separated from each other, which means there is a galvanic separation between inputs, outputs and between the two amplifiers.

If you connect several isolation amplifiers to a PLC or the like, the plus connections on the output of the amplifiers are connected to plus on the power supply, and the different minus-outputs are connected to the plus inputs on the PLC. Minus from the supply is then connected to common minus on the PLC.
If the PLC has a voltage output for the supply of external sensors, you can use this instead of an external power supply, on the condition, that is can supply the neccessary power.
