Refer to the “RELAY” section to check the possible UG 6914.04/000, UG 6914.04/008 operation modes
configurable with SAFEMASTER PRO Designer software
To guarantee correct isolation and avoid the risk of premature ageing of or damage to the relays, each
output line must be protected using a fast 4 A fuse and the load characteristics must be consistent with
those specified in the upper table.
See the "Output module relay UG 6912.14 - UG 6912.28" section (for further details on these relays).
SAFETY RELAYS (MODULE UG 6912.14, UG 6912.28, UG 6914.04/000, UG 6914.04/008)
Characteristics of the output circuit
The UG 6912.14, UG 6912.28 relay modules use guided contact safety relays, each of which provides
two N.O.
contacts and one N.C contact in addition to the N.C. feedback contact.
The UG6912.14 unit uses two safety relays and the UG6912.28 uses four
The UG 6914.04/000, UG 6914.04/008 units use four guided-contact safety relays. Each relay provides one
NO contact monitored by the module logic through internal FBK contact.
