INDUSTRIAL/SRSE-2NO SAFETY RELAY MODULE
CHARACTERISTICS OF THE OUTPUT CIRCUIT
For the output circuit, the safety relay module uses two guided contact safety relays.
These relays are rated by the manufacturer for voltage and current values above those indicated in the
technical data; however, to enable correct insulation and to significantly reduce potential damage or premature
aging, protect each output line with an appropriate fuse (depending on the load). Check that load
characteristics comply with the indications given in the table below.
Minimum switching voltage
18 VDC
Minimum switching current
20 mA
Maximum switching voltage
250 VAC
Maximum switching current
6A(AC) / 6A(DC)
USE OF K1 AND K2 AUXILIARY CONTACT ELEMENTS.
For loads with higher voltage and current characteristics than those indicated in the table above, use of
auxiliary external relays or contactors suitable for the load to be controlled is recommended.
•
The K1 and K2 auxiliary contactors or relays must be of the guided contact safety type.
•
Referring to the table below, pay particular attention to the configuration of the control contacts on
terminal 11 and that of the contacts of use.
Auxiliary Relay K1
Auxiliary Relay K2
Control contacts
K1-1 normally closed
K2-1 normally closed
Use contacts
K1-2 normally open
K2-2 normally open
•
Control contacts K1-1 and K2-1 (terminal 11) must be able to switch a current of 10mA and a voltage of
24VDC.
