Wired-OR output
Using on Wired-OR Logic
• When connecting a relay or LED lamp, ensure
that the relay or lamp operates at up to 30 V and
20 mA
(with allowable loss of 75 mW or less).
When connecting a relay, be sure to use a diode
to absorb counterelectromotive force.
• Open collector output operates on wired-OR
logic by short-circuiting TEMP and HUM. More-
over, it enables the signal if an alarm occurs in
either channel.
