Electrical data
Type of voltage: DC coil, AC voltage is rectified by a rectifier
built-in the plug
Nominal current at 20°C: 984 mA at 12 V DC
492 mA at 24 V DC
Voltage tolerance: +/- 15% of Coil voltage
Coil duty rating: 100% continuous up to max.
115% of Coil voltage at 60°C
ambient temperature
Switching time: Energized: approx. 30 - 60 ms
De-energized: approx. 20 - 40 ms
FUNCTION
In de-energized mode all ports are
blocked.
If the coil S1 is energized, there is
free flow from port 3 to 4 and from 2
to 1.
If the coil S2 is energized, there is
flow from port 3 to 2 and from 4 to 1.
