CPH6000
The internal 24 V power supply must not be short-circuited and
nor should the maximum output current through the circuit
exceed 50 mA. (In addition, the current should not drop below
20 mA in order to ensure accurate current measurement)
4.1 Electrical connections for potential-free contact pressure switches
Only potential-free (passive) switches, as shown in the drawing
and using the supplied test cable, should be connected to the
CPH6000.
A current or voltage input could damage the CPH6000.
