Max. 100 mA
Duty cycle at f > 2 Hz
0,5
Minimum pulse length at f < 2 Hz
250 ms
Safety

vanically isolated
Type
Relay output
Function (adjustable)
Hysteresis (default setting), hysteresis/window mode, reverse flow direction
message, generate a warning message
Switching output
N/O contact
Switching capacity
3 A at AC 250 V resistive load, 3 A at DC 40 V resistive load

Galvanic isolation
Mixed switching of mains voltage AC 230 V and SELV or PELV voltage is
not admissible due to the basic insulation between the relays!
