10-6 TOS5051A/5050A
Signal Output
8
The ratings of the open-collector signal are 4.5 V to 30 VDC, 400 mA (maxi-
mum, in total). The above open-collector output circuits are isolated from other
internal circuits. except that the common lines of the output circuits are directly
connected to those of the signal input circuits. The common lines of all open-
collector circuits are connected together. The ratings are 30 VDC, 30 VACrms
MAX.
9
Loudness of the buzzer for PASS/FAIL annunciations can be controlled with the
buzzer control. It is in common for both PASS and FAIL annunciations--it does
not control them separately.
10
The rating of the 100-VAC output signal is 0.3 A (maximum).

STATUS OUTPUT When one of the DIP switches for the follow-
ing items is set to ON and the corresponding
status has occurred. If two or more items are
set to ON, the signal is delivered on the logi-
cal sum of such items.
