Description

The electronic relay module 750-522 switches a supply voltage up to 230V
AC for connected actuators or AC loads.
The module has two output channels. Two actuators with ground (earth) wire
may be directly connected.
The module is equipped with two TRIACs as switching relays. The semicon-
ductor outputs of the TRIACs allow for the unlimited triggering of the actua-
tors while having no wear on the outputs
The TRIACs are non-floating, i.e. the fieldside voltage supply (35 VAC up to
230 V) is connected to each terminal of the relay and is fed in via the internal
power jumper contacts of an adjacent supply module.
By closing a relay, the field power applied is switched to the second relay con-
nection DO1 or DO2.
The control of the semiconductor outputs is fully isolated using the internal
system voltage. The outputs are switched at the zero cross.
