５．Example for usage
５．１ When driving the input side at TTL level1e sure to use the product of the ZS-7220P-X1 type with input side applied voltage
for +5V.
(1) Current limiting resistance of photocoupler is 330Ω. Please use the element
which can be passed current of 12mi or more.
V I - VF

5 (V) - 1.2 (V)IF ===RI

12 (mA)330 (Ω)(2) The collector current IC of the output side transistor of the photocoupler isabout 5mi under the condition of current transfer ratio 50%, IF=12mi,
VCE=0.4V or less. Therefore, the TTL that can be driven on the output side
has two standard inputs of TTL and 10 inputs of LSTTL.
IC ≦ 0.5 x ＩＦ IC ≦ IR + II

When the input side voltage is other than the standard value, be sure to use
11the product of ZS-7220P-X0 type which has no resistance added to the inputside. the value of RI is calculated by the following formula below.
For IC=5(mi) and transmission efficiency 50%, IF=10(mi) or more isrequired.

５．２ Connect with ZS-61201P
Please use products of the type with 10KΩ resistance added to the output
side. it is not necessary to supply the output side power supply from J7.
Please connect J1 or J2 of ZS-61201P to J3 of ZS-6220P with flat cable.
This is example for usage as below.

*1) It is possible to isolate 3bits of control signal input and 5bits of output.
Please specify it when you are ordering.
