The internal power supply voltage for the module's circuitry is carried out via the I/O bus
(provided by a communication interface module or a CPU). Thus, the current consumption from
24 V DC power supply at the terminals L+/UP and M/ZP of the CPU/communication interface
module increases by 2 mA per DA502.
The external power supply connection is carried out via the UP (+24 V DC) and the ZP (0 V DC)
terminals.
