2-3. Wiring
Open the wiring cover and connect the transmission cable and power cable (24 VDC) to the wiring
terminal.
With a knife, cut the center of the rubber grommet on the side of the transmission block, and put the
wires into the transmission block case.
(Grommet model and manufacturer: rubber grommet, model SG-22A manufactured by Kyowa Rubber Industry CO.,
LTD.)
The screws on the wiring terminal are M3 screws. Use crimped terminals (JIS 2805 R-type 1.25-3
equivalent) suitable for the terminal screws. Furthermore, do the wiring according to the labels.

Precautions for wiring
1. The transmission block is a 16 output type (for receiving).
The transmission signal from a 10 output type is not compatible, so it cannot be connected.
2. Avoid placing transmission lines near or parallel to high-voltage lines or high-current lines. If you
wire the lines near a source of noise, confirm in advance that there will be no problems or
malfunctions.
3. Doing wiring work while the power is on may result in short circuits, such as by the cables
contacting the terminals, and damage internal components. Do not energize the circuit while doing
wiring work.
4. Connecting (shorting) the power to a SIG terminal while transmitting will cause a malfunction.
Confirm that there are no short circuits in the wiring or other places before turning on the power.
5. If you need to measure the insulation resistance of the transmission cable, disconnect the cable to
be measured first and then check the cable insulation resistance without connecting other devices.
6. To use the error output
i) Immediately after turning on the power, an error occurs. (Less than 300 ms after connection.)
Be careful when using the error output.
ii) A short circuit (in an unloaded state) between the error output terminal (ERR) and the power
supply terminal (24 V terminal) causes a malfunction.
Connect a suitable load that remains below the rated voltage (40 mA).

3. Output relay and solenoid valve connections
The serial transmission block has 16 outputs, 0 to 15. The relationship between the output relay
numbers in the program and the actual mounted solenoid valves is shown below.
The relationship between all the solenoids on the manifold and output relay numbers is different
depending on what is specified for &quot;Wiring specifications&quot; in the manifold ordering codes.
Wiring specifications
Blank (packed wiring): Wired according to specifications of mounted valves.
-W (double wiring): All wiring is for double solenoids, regardless of the
specifications of the mounted valves.
If wiring specifications are &quot;blank&quot;
(packed wiring)
The valves specified in the single solenoid
specifications (F T1) when ordering are
wired to solenoid A only and are not wired to
solenoid B because wiring is done according
to specifications for the mounted valves.
This means that it cannot function as a
double solenoid valve after it is delivered
because no current flows to solenoid B, even
if it is switched from a single solenoid valve
to a double solenoid valve.
hen wiring specifications are &quot;-W&quot;
W
(double wiring)
All wiring is for double solenoids.

Frequently asked questions

The serial transmission block requires a power supply voltage of 24 VDC ±10%.

The operating temperature range for the serial transmission block is 5 to 50°C [41 to 122°F].

The serial transmission block allows you to select between HOLD and LOAD OFF settings for output during abnormalities. HOLD retains the state before the fault occur, while LOAD OFF turns off all outputs. The factory default setting is LOAD OFF.

The maximum transmission distance for the standard type YS231 is 500m [1640 ft] when a separate power supply is used for input and output.
