3.2 Principle of Operation 
3.2.1 Program
The SiO controller program sets the conditions for turning ON each output and how long it is kept
turned ON.
Programs are edited and registered by using the dedicated software, SiO-Programmer.
The following four items are set.
1. ON conditions: Conditions for turning ON each output
2. Status: Conditions or waiting time for turning ON each output
3. OFF conditions: Conditions for turning OFF each output
4. Output method: Method of output
Example: When turning ON OUT1 for 5 seconds after IN1 turns ON
IN1
OUT1
5 seconds
For details, see “4 SiO-Programmer” or the “SiO-Programmer Instruction Manual.”

3.2.2 Cycle Time
The SiO controller repeats the above processes.
The time required to execute these three processes once is called cycle time.
The cycle time of the SiO controller is 5 msec.
It is constant regardless of the number of registered programs.
3.2.3 Input Response Time
The input ON/OFF time must be set to 10 msec or more.
Failure to do so may fail to read programs.
Therefore, the input response time is 10 msec + cycle time.

3.3 Installation 
3.3.1 Installation of Controller
Install the controller observing the following precautions.
◆Avoid installation in direct sunlight.
◆Prevent foreign matter from entering the controller.
◆Avoid using in a place with high temperature, high humidity, dust, iron powder, cutting oil, or
the like.
3.3.2 Wiring to Controller
Wire the AC adapter and I/O cables as follows.
Be sure to turn OFF the power before wiring.
1. Wiring to controller and power connector
Connect 24 V DC to the power connector. It is recommended to use the dedicated AC adapter.
Otherwise, prepare a plug of the following size:
Do not supply power except from the power connector.
Because it does not pass through the protection circuit,Controller may fail.
5.5 mm (OD) ×2.1 mm (ID), Wiring symbol:
Plug Jack
2. Connection of I/O cables
Connect I/O cables to the input/output connectors.
* Be sure to insert each connector until it clicks.
Before connection After connection
Be sure to push down the lever before disconnecting the connector.
Forcibly pulling out the connector may result in a break in the wire.

Slide the switch to “RUN” (right) to run, and to “STOP” (left) to stop the program.
When the program stops, outputs are all turned OFF.
Be sure to set the RUN switch to “STOP” before registering a program from the SiO-Programmer.
3.4.2 Timer Setting
The SiO controller has two timer setting trimmers.
They are used when T1 or T2 is selected by the program.
