(Connection Type)
• Output specifications
NPN open collector output
DC+5 to +26.4 V 10 mA or less (150 mW or less)
Note
When connecting a device such as a relay to output pins,
first check the operational coil rating of the relay.
Be sure to connect a back-voltage absorption diode in
parallel with the coil.
• Input specifications
OFF voltage: +4 to +26.4 V or open
ON voltage : +0.8 V or less
Between IN and GND, either open (OFF) or short (ON) is
possible
Output signal rating
On: VOL = MAX. 1.4 V (when output current IOL = 10 mA)
Off: VOH = MAX. 26.4 V (output current IOH = MAX. 50 µA)
External power
supply:
DC +5 to +24 V
