6.1 Relay Unit
The SG4-00VA000R2 relay unit is equipped with two failsafe floating relay outputs. The terminals are connected to
the load circuit. The use of a spark arrestor significantly increases the service life of the relay contact. Two-channel
redundant wiring must also be observed when the relay unit is utilized. Both contacts must be used for load cur-
rent control.
GEFAHR!
Response times are increased by 8 ms when the relay unit is used.
