4.6 For Input Connection
●
Pulse input
・
Contact input
Use highly reliable metal plated contacts. Since the contact
’
s bounce time leads directly to error in the
count value, use contacts with as short a bounce time as possible. In general, select 30Hz for
max.counting speed.
・
Non-contact input (Transistor input)
Connect with an open collector. Use the transistor with the following specifications.
V
CEO
=20V min. I
C
=20mA min. I
CBO
=
6μ
A max.
Use transistors with a residual voltage of max. 3V when the transistor is ON.
* Short-circuit impedance should be
1kΩ
max.
Open-circuit impedance should be
100kΩ
min. When the impedance is
0Ω,
the drain current is
approx. 10mA.
・
Input wiring
Please wire as short as possible by using a shielded wire or a metallic electric wire tube individually.
4.7 For Output Connection
●
PhotoMOS relay output
・
With a PhotoMOS relay output, there is no polarity.
Output: Rated capacity 30V AC/DC, 0.1A
・
Do not connect devices with a voltage or load that exceeds the rated capacity (30V AC/DC,0.1A)
・
Please do not exceed the maximum wire length of 100m for the outputs. If the wire is longer, it may not
work correctly due to a floating capacitance.
