This relay module for VLA 31 is avalilable in IP20.
The connecting drawing on page 2 must be followed.
The DC voltage supply for VLA 31 has been changed
from 15 V to 24 V, and 6 light emitting diodes have
been mounted on the frontplate of the relay module:

■ The LED “POWER” lights up, if the supply voltage
is OK and the fuse protecting the DC voltage
supply is intact.

■ The LED’s 1-5 light up, when the relays of the
corresponding numbers are energized.
