2. Cautions

 Verify that the supply voltage variation is within the rating. Also, check the voltage variation at

the end terminal of the transmission route, since voltage drop occurs depending on the diam-

eter or the length of the transmission cable.

 If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.)

terminal of the power supply is connected to an actual ground.

 Do not use during the initial transient time (approx. 0.5sec.) after the power supply is switched

ON.

 Make sure to use an isolation transformer for the DC power supply. If an auto-transformer (sin-

gle winding transformer) is used, this product or the power supply may get damaged.

 In case a surge is generated in the power supply used, connect a surge absorber to the supply

and absorb the surge.

Power supply

 Do not run the wires together with high-voltage lines or power lines or put them in the same

raceway. This can cause malfunction due to induction.

 Make sure to carry out the installation and wiring in the power supply OFF condition.

 In order to reduce noise, make the wiring as short as possible.

Wiring

 This product has been developed / produced for industrial use only.

 In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the

vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual

ground.

 Do not use the product in places where there is excessive vapor, dust or corrosive gas, or in a

situation where the product could be exposed directly to water or chemicals.

 Do not use the product in places where the ambient temperature or the humidity exceeds the

 This is an area to read out input data and write in output data of S-LINK units.

In case of input, “0: Input OFF” or “1: Input ON” is read out in each bit.

In case of output, write in “0: Output OFF” or “1: Output ON” in each bit.

Notes: 1) Output is saved until you overwrite with the next output data.

2) In case output data is written into a unit address which has been set as an input, the written data is

ignored and new input data is set after 1.4 to 10.7ms.

When “1” is written, the connection condition of the S-LINK units at that time is read.

(It becomes “0” after the completion of reading.)

bit 7 : In case of sending different outputs to the same address, the former output data will

be ignored if the next output data is written in before the former output data has been

transmitted to the S-LINK output unit.
