Coil data
Nominal energizing voltage Typical nominal power consumption monostable with 1 winding bistable with 2 windings bistable with 1 winding From 3V– to 48V– 150 ... 250 mW 150 ... 200 mW 75 ... 100 mW (depending on the coil version, see table) 70 ... 80 % of the nominal energizing voltage, depending on the coil version 75 % of the nominal energizing voltage 10 % of the nominal energizing voltage 35 % of the nominal energizing voltage
Maximum operating voltage Maximum reverse voltage (bistable) Minimum release voltage (monostable) Maximum holding voltage (non-releasing, monostable) UI = minimum voltage at 20 °C after pre-energizing with nominal energizing voltage without contact current = maximum continuous voltage at 20 °C
UII
The operating voltage limits UI and UII are dependent on the temperature according to the formulae:
UI tamb = kI · UI 20 °C and UII tamb = kII · UII 20 °C tamb = UI tamb = UII tamb = kI a. kII =
