6 Expansion modules
Expansion modules are used to increase the number of safety outputs and can be connected to a normal
safety relay. The number of expansion modules connected to a safety relay should not exceed 6. There are
two possible versions available :
type specialties safety output auxiliary outputs
opposite polarity
between channels

SAFE IRZ.2 / RS – NAGX 5 : conversion of semiconductor output to relay output
(RS-NAGU, NAGU.1, RS- NAGU.1b, RS-NAGU.12)
Function diagram SAFE X4
A transformer is used for the following voltages:
48, 110-127, 230VAC.
A electrical fuse is used instead of an transformator with the 24VAC/DC voltage device.
