Binary Inputs
Standard Binary Input
Rated voltage range DC 24 V to 250 V
The binary inputs of SIPROTEC 5 are bipolar, with the exception of the
binary inputs on the modules IO230, IO231, and IO233.
Current consumption, excited Approx. DC 0.6 mA to 2.5 mA (independent of the control voltage)
Power consumption, max. 0.6 W
Pickup time Approx. 3 ms
Dropout time

Capacitive load (supply-line capaci-
tance)
Dropout time
< 5 nF < 4 ms
< 10 nF < 6 ms
< 50 nF < 10 ms
< 220 nF < 35 ms
Control voltage for all modules
with binary inputs, except
module IO233
Adapt the binary-input threshold to be set in the device to the control
voltage.

The binary inputs contain interference suppression capacitors. To ensure EMC immunity, use the terminals
shown in the terminal diagrams/connection diagrams to connect the binary inputs to the common potential.
Special Binary Input with Maximized Robustness against Electrical Disturbances and Failures (IO216)
Rated voltage range
DC 220 V
The special binary inputs of the SIPROTEC 5 with maximized robustness
against electrical disturbances and failures are bipolar and available only
on the module IO216.
Input impedance 50 kΩ to 60 kΩ
Rejection pulse charge > 200 µC
Current consumption, excited Approx. DC 1.2 mA to 2.0 mA (additionally to the current consumption
of the input impedance)
Power consumption, max. 1.5 W at DC 242 V
Pickup time Approx. 3 ms

For time-critical applications with low-active signals, consider the specified dropout times. If necessary, provide for active discharge
of the binary input (for example, a resistor in parallel to the binary input or using a change-over contact).
