E2638-H2S

Rev 21.06.2021

NOTE! The outputs are not galvanically isolated from the external power supply and share a
common 0V. Allowed load resistance limits are stated in the Speciﬁcations table. To power
the instrument from an external power source, connect terminals 0V and +U to the source.
If the integrated mains power supply module is used, connect terminals L and N to the
mains.

NOTE! Actuator short-circuits should be avoided, to protect the instrument relays, use
external fuses or safety switches.
