Interface Circuit

Input Circuit
SI Connection to sequence input signals
• 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 to 24V) as 11.4V or more in order to secure the primary
current for photo-couplers.
12 to 24V
PI1 Connection to sequence input signals (Pulse train interface)
(1) Line driver I/F (Input pulse frequency : max. 500kpps)
• This signal transmission method has better noise immunity.
We recommend this to secure the signal transmission.
(2)Open collector I/F (Input pulse frequency : max. 200kpps)
• The method which uses an external control signal power supply (V
• Current regulating resistor R corresponding to V
required in this case.
• Connect the specified resister as below.

represents twisted pair.
PI2 Connection to sequence input signals
(Pulse train interface exclusive to line driver)
Line driver I/F (Input pulse frequency : max. 2Mpps)
• This signal transmission method has better noise immunity.
We recommend this to secure the signal transmission
when line driver I/F is used.
AI Analog command input
• The analog command input goes through 3 routes,
SPR/TRQR(Pin-14), CCWTL (Pin-16) and CWTL (Pin-18).
• Max. permissible input voltage to each input is ±10V.
For input impedance of each input, refer to the right Fig.
• When you compose a simple command circuit using variable
resistor(VR) and register R, connect as the right Fig. shows.
When the variable range of each input is made as –10V to
+10V, use VR with 2kΩ, B-characteristics, 1/2W or larger, R
with 200Ω, 1/2W or larger.
• A/D converter resolution of each command input is as follows.
(1)ADC1 : 16 bit (SPR/TRQR), (including 1bit for sign), ±10V
(2)ADC2 : 10 bit (CCWTL, CWTL), 0 – 3.3V
