Hardware features and power supplying

The module is enclosed in a plastic casing adapted for mounting on a DIN-rail. The box has a standard

circuit

breaker” profile and width of two standard DIN-modules. The module is equipped with a

M-Bus data bus

screw-on terminal

with two clamps.

The module needs an external power supply 24V DC. For connecting of the power supply there is a screw-on
terminal with marked voltage polarity. Power supplying must follow all the safety requirements according to the
appropriate standards. Maximum current consumption of the module (for voltage of 24 V) is up to 50 mA, the
module is protected on the power supply input by reversible fuse with release current of 300 mA.

The module cannot be used in exteriors without additional covering. External appearance of the WM868-MS-LP-H
module is shown in the Figure
