Technical Manual
Product and Applications Description
The time switch REG 372 is a DIN-rail mounted
device laterally attached to the bus coupling unit
REG 110 (to be ordered separately, order number:
5WG1 110-5AR01). During this it occupies 4 address-
ing locations of the bus coupling unit. Via the four
channels time controlled applications such as illumina-
tion, heating or shutters can be switched on or off. It
can be used as daily, weekly or yearly clock controller.
By connecting an aerial FA and a power unit NT DCF77
the clock controller itself automatically sets the up-to-
date daytime and date (MEZ).
With a reading button the set switching times, date
referenced inputs and 1x-switching commands can be
trialled.
The bus coupling unit REG 110, the power unit
NT DCF77 and the radio aerial FA are not contained in
the volume of delivery and must be ordered separately
