Sequence Output Circuit
• This output circuit is configured with a Darlington connection
transistor output of open collector. It is connected to a relay
or photo coupler.
• Due to Darlington connection of the output transistor, there
exists a collector-to-emitter voltage V CE (SAT) of approx. 1V
upon power-ON of the transistor. Note that normal TTLIC
cannot be directly connected since it does not meet V
IL
requirement.
• When a recommended value of primary current of a photo
coupler to be used is 10mA, determine a resistance value
with the following formula:
For a recommended primary current value, check the data
sheets of equipment or photo coupler you plan to use.

Be sure to install in the direction shown in the figure.
Line Driver (Differential Output) Output
• Provide differential outputs of encoder signal output (Phases A,
B and Z) after dividing operation is performed, by respective
line drivers.
• On the host controller side, receive signals with a line receiver.
Then, be sure to install termination resistor (approx. 330
Ω)
between inputs of the line receivers.
• This is non-insulated output.

Open Collector Output
• Among signals from the encoder, output phase Z signals with
the open collector. This is non-insulated output.
• On the host controller side, use a high-speed photo coupler
for reception, since pulse width of phase Z signal is usually
narrow.

Connection with Sequence Input Signal
• Connect to a contact of switch and relay, or a transistor of an
open collector output.
• When you plan to use a contact input, use switch and relay
for minute electric current so as to avoid poor contact.
• In order to secure appropriate level of primary current of the
photo coupler, set lower limit voltage of the power supply (12
to 24 V) above 11.4V.
