Maximum switching load
Minimum switching load
500,000 times or more （Switching frequency 30 times/min）
Setting in five kinds of modes as follows is possible for operation of detection.
① High limit detection (H), Detection operation, Relay excitation
② High limit detection (H), Detection operation, Relay non-excitation
③ Low limit detection (L) , Detection operation, Relay excitation
④ Low limit detection (L) , Detection operation, Relay non-excitation
⑤ OFF
MAX. 4 contacts. Monitor lamp lights when each relay is excited.
The monitor lamp blinks during the delay time when the pre-alarm setting is ON.
Auxiliary supply OFF, or
relay non-excitation.
