H8CA-S
Input type Counter output Signal high Signal low
No-voltage Contact The contact turns ON The contact turns OFF
Solid-state The open collector transistor is in the ON state The transistor is in the OFF state
Voltage Both Input signal voltage level is 5 to 30 V Input signal voltage level is 0 to 2 V
■ FUNCTIONS OF INPUT SIGNALS
Input Counter mode A Counter mode B Counter mode C Timer
(command input) (individual input) (phase difference) operation
Count input 1 Count input: Addition count The count value is increased Start input
The count value is input by one when phase of count
increased by one input 2 (CP2) is delayed with
when count input 2 (CP2) respect to phase of count
voltage goes low. The input 1 (CP1).
count value is decreased The count value is decreased
by one when count input 2 by one when phase of count
(CP2) voltage goes high. input 2 (CP2) is ahead with
respect to phase of count
input 1 (CPI).
Count input 2 Addition/subtraction control Subtraction count input Gate input
Output Mode N Present value display and outputs are
maintained until reset.
Output Mode F Present value runs continuously. Outputs
are maintained until reset.
Output Mode C Present value is placed in reset start status
as soon as preset count is reached; the preset is not actually
displayed. Outputs are one-shot, fixed at 0.5 second, and
operate repeatedly.
Output Mode R Present value display returns to reset start
status after expiration of one-shot time period. Outputs are
one-shot, fixed at 0.5 second, and operate repeatedly.
