The output signals are powered by the internal 5 V source or by an external
5 to 24 V source. The output stages provide an active low transistor and also
an active high transistor.
• Internal supply: V
5-24 V
= 4.5 to 5 V at I ≤ 100 mA
• External supply: V
5-24 V
= 5 to 24 V at I ≤ 600 mA
• Low output signal: V
OL
= 0,5 to 1 V at I
OL
≈ 200 mA
• High output signal: V
5-24 V
- V
OH
= 1,5 to 2,5V at I
OH
≈ 200 mA
