• Connect to contacts of switches and relays, or open collec-

tor 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.

• The output circuit is composed of open collector transistor

outputs in the Darlington connection, and connect to relays or

photo-couplers.

• There exists collector to emitter voltage, V

(SAT) of approx.

1V at transistor-ON, due to the Darlington connection of the

output or. Note that normal TTL IC cannot be directly connec-

ted since it does not meet VIL.

• There are two types of output, one which emitter side of the

output transistor is independent and is connectable individual-

ly, and the one which is common to – side of the control pow-

er supply (COM–).

•

If a recommended primary current value of the photo-coupler is

10mA, decide the resistor value using the formula of the right Fig.

Sequence output circuitSO1

• Feeds out the divided encoder outputs (A, B and Z-phase) in

differential through each line driver.

• At the host side, receive these in line receiver. Install a termi-

nal resistor (approx. 330Ω) between line receiver inputs with-

out fail. 

• These outputs are not insulated.

Line driver (Differential output) outputPO1

• Feeds out the Z-phase signal among the encoder signals in

open collector. This output is not insulated.

• Receive this output with high-speed photo couplers at the

host side, since the pulse width of the Z-phase signal is nar-

row.

Open collector outputPO2

For the recommended primary current value, refer to the data sheet of apparatus or photo-coupler to be used.
