Input method
1. Standard type
Notes) 1. When using contact input, since current flow is small from terminals
1
and
3
on the panel mounting type and terminals
e
to
t
and
S
to
F
on the PC board
mounting type, please use relays and switches with high contact reliability.
2. When using transistor input, use the following as a guide for which transistors (Tr) to use for inputting. (Collector withstand voltage
Q
50 V, leakage current < 1 µA)
Notes) 1.
2
and
4
. (The input and reset circuits are functionally insulated.)
2. When using transistor (Tr) input, use the right as a guide. (Collector withstand voltage
Q
50 V, leakage current < 1 µA)
3. Be aware that the application of voltage that exceeds the voltage range of the H level to the count input terminal, and the application of voltage to the reset input
terminal, can cause damage to the internal elements.
