Note
• Connect to contacts of switches and relays, or open collector output transistors.
• When you use contact inputs, use the switches and relays for micro current to avoid contact
failure.
• Make the lower limit voltage of the power supply (12 V to 24 V) as 11.4 V or more in order to
secure the primary current for photocouplers.

(1) Line driver I/F (
Permissible max. input frequency of command pulse input signal. : 500 kpulse/s)
• This signal transmission method has better noise immunity.
We recommend this to secure the signal transmission.
(2) Open collector I/F (
Permissible max. input frequency of command pulse input signal. : 200
kpulse/s)
• The method which uses an external control signal power supply (VDC)
• Current regulating resistor (R) corresponding to V
DC
is
required in this case.
• Connect the specied resister as below.
• (R) should be placed close to the driver for effective noise reduction.
(3) Open collector I/F (
Permissible max. input frequency of command pulse input signal. : 200
kpulse/s)
• Connecting diagram when a current regulating resistor is not used with 24 V power supply.
