Binary Inputs

The 2 binary inputs BI-1 and BI-2 operate across a wide input-voltage range. Logic 1 (high) is a voltage level
from DC 24 V to 250 V, -20 %, +15 %, with polarity-reversal protection and a pickup threshold of 18 V. In
exceptional cases, for example, with long unshielded lines and a disturbing influence, the pickup threshold
can be set to about 75 V (see
Logic 0 (low) is a voltage level below the set pickup threshold. When the corresponding binary input is acti-
vated, the corresponding yellow LEDs (BI-1, BI-2) light up.

If the optical fiber or RS232 is being used for communication, the LEDs K1 and K2 indicate the state of the
binary inputs on the remote station.
