Inputs

Outputs
Note: The input and output signals are enabled when power is applied to the Counter. During a power failure, the input signals are disabled, and the output signals are
turned OFF.
Count 9 inputs
•
Input count values.
•
Used as time count input signal when timer is used.
•
Max. counting speed receivable: Count inputs 1 to 7: 30 Hz (Min. signal input width: 16.7 ms), Count inputs 8 and 9: 30 Hz/500 Hz
(Min. signal input width: 16.7 ms/1 ms)
Reset 1 input
•
Resets count/time value of a displayed Counter No.
•
Counter under reset does not operate as its output is turned OFF.
•
Reset signal input received while re-monitor function is ON restores reset count/time value of the specified counter.
•
While reset signal is ON, RESET indicator lights.
Short
•
When the short input is ON, an input is also received for one of the count inputs 2 to 9 when an input is received for count input 1. The
H8BM can thus be used as a multi-stage preset counter without performing external short-circuit wiring.
Counter No. selection
•
Specifies counter whose count/time value is to be displayed.
I/O inhibit
•
Inhibits count inputs of all counters.
•
Turns OFF all forecast outputs, RUN outputs, and machine stoppage outputs.
•
While I/O inhibit signal is ON, INHB indicator lights.
Forecast 9 outputs
•
Each of these outputs turns ON when its forecast value has been reached.
•
When a total counter is used, output one-shot signals as carry signals.
•
Retain outputs until count values are reset.
RUN 1 output
•
Turns ON when Counter is operating normally.
Machine stoppage
1 output (Common)
•
Turns ON when count value of one counter has reached set machine stoppage value.
•
Retains output until count value is reset.

H8BM-R
Note 1. H8BM-RAD/-RBD outputs the forecast and machine stoppage values simultaneously.
2. The I/O terminals are used for both PNP and NPN. There is no polarity.
Note 1. When the load is short-circuited, the internal
circuits may be damaged.
2. Connect a diode to suppress Counter surge when
an inductive load is connected.
