Electrical Data for Inputs and Outputs
The inputs and outputs of the emission controller have the following electrical data:
Inputs and outputs Values/characteristics
Binary inputs – Input voltage up to 32 V DC
– Input current at least 5 mA for high level (approx. 12 mA at
24 V DC)
– galvanically isolated
(rated insulation voltage: max. 70 V DC)
When the reset signal is given, the high level must be present
at the relevant input for at least 50 ms before it is possible to
initiate the reset.
Binary outputs – Inactive: output is high-impedance
– Active: output is low-impedance
– Switching voltage: max. 32 V
– Current: max. 100 mA
– Max. voltage drop at 100 mA: 2.5 V
– galvanically isolated
(rated insulation voltage: max. 70 V DC)
Analog voltage input – Permissible voltage: 0 V to 10 V
– Input resistance: 12.4 kΩ
Analog current input – Permissible current: 0 mA to 20 mA
– Max. difference in potential relative to device ground:
+3.5 V
– Input resistance: max. 25 Ω
Analog voltage output – Output voltage: 0 V to 10 V
– Working resistance: min. 500 Ω
Analog current output – Output current: 0 mA to 20 mA
– Working resistance: max. 500 Ω
Electrical Data for Connection of the Pump Module
The connections of the pump module have the following electrical data:
Feature Value
Power supply for the pump 18 V DC to 32 V DC; max. 1.5 A
