Properties
Properties of relay output module SM 322; DO 8 x Rel. AC 230V/5A:
● 8 outputs, electrically isolated
● Load voltage 24 VDC to 120 VDC, 24 VAC to 230 VAC
● Suitable for AC solenoid valves, contactors, motor starters, FHP motors and signal lamps
● You can protect the contacts with an RC quenching element by setting a jumper (SJ.)
● Group error display
● Channelspecific status LEDs
● Programmable diagnostic interrupt
● Programmable substitution value output
Overvoltage protection of contacts
You can protect the contacts against overvoltage by bridging (SJ) the module terminals 3
and 4, 7 and 8, 12 and 13 etc. (refer to the figure below.)
