Sensing output
NPN open-collector transistor
・Maximum sink current: 100 mA
・Applied voltage: 30 V DC or less (between sensing output and 0 V)
・Residual voltage: 1.0 V or less (at 100 mA sink current)
        0.4 V or less (at 16 mA sink current)
Sensing output:Output operationSelectable either Light-ON or Dark-ON with the ON and OFF buttons (Selectable with the external inputs for SU-77)
Sensing output:Short-circuit protectionIncorporated
Self-diagnosis output
NPN open-collector transistor
・Maximum sink current: 50 mA
・Applied voltage: 30 V DC or less (between self-diagnosis output and 0 V)
・Residual voltage: 1.0 V or less (at 50 mA sink current)
        0.4 V or less (at 16 mA sink current)
Self-diagnosis output:Output operationON under unstable sensing condition (restored automatically after 40 ms approx.), or if the sensing output is short-circuited (restored when short-circuit is rectified).
(For the remote sensitivity adjustment type, it turns ON for 40 ms approx. Also after the remote sensitivity input is received.)
Self-diagnosis output:Short-circuit protection-
Response time0.6 ms or less (0.8 ms or less when the interference prevention function is used)
Operation indicatorRed LED (lights up when the sensing output is ON)
Stability indicatorGreen LED
("RUN" mode: Lights up under stable light received condition or stable dark condition
"SET" mode: At the time of sensitivity setting, blinks twice when the difference between ON and OFF levels is greater than the hysteresis, but blinks 15 times when it is equal to or less than the hysteresis. Also blinks twice after the interference prevention is set
"SET" mode → When "SIF" or "RUN" mode is selected: Blinks from 0 to 5 times according to the sensitivity margin)
Test input (emission halt) function-
External synchronization function-
Remote sensitivity setting functionIncorporated
Remote sensitivity selection function-
Sensitivity shift & limit sensitivity setting functionsShifts the set sensitivity level
Automatic interference prevention functionIncorporated
