EX-A2X 用通信线缆连接模块的PLC 适配器

用通信线缆连接模块的PLC级联口和PLC。
注意连接正确的电缆。这种电缆的连接器包裹在黄色绝缘材料中。注意，一端标记为PLC，另一端标记为适配器;插入相应。
该模块提供1米电缆，部件号EXL-CAB100。其他电缆长度也可用。
请使用原电缆，不得进行任何修改。

适配器提供OPLC和级联模块之间的接口。将I/O模块连接到适配器或另一个模块。
1. 将模块对模块连接器插入设备右侧的端口。
请注意，有一个保护帽提供的适配器。这个盖子覆盖了系统中最终I/O模块的端口。

接线采用压接端子;使用26-12AWG线(0.13 mm2 -3.31 mm2)
)，以作所有布线之用。
1. 剥线至长度为7±0.5mm(0.250-0.300英寸)。
2. 在插入电线之前，将端子拧到最宽的位置。
3. 将导线完全插入端子，以确保正确连接。
4. 拧紧到一定程度，以免金属丝被扯开。
为避免损坏线缆，最大扭矩不能超过0.5 N·m (5kgf·cm)。
不要在剥离的电线上使用锡、焊料或任何其他可能导致线束断裂的物质。
安装时尽量远离高压电缆和电力设备。

1. 将“正极”电缆连接到“+V”端子，将“负极”电缆连接到“0V”端子。
务必将功能接地引脚连接到接地上。为此使用专用电线;它不能超过1米。
请勿将110/220VAC的中性或线路信号连接到设备的0V引脚上。
如果电压波动或不符合电压电源规格，请将设备连接到稳压电源上。
如果机箱上有0V信号，则可以使用非隔离电源。
注意OPLC和EX-A2X必须连接在同一电源上。
EX-A2X和OPLC必须同时打开和关闭。

EX-A2X

Use the communication cable to connect the module’s PLC expansion port to the PLC.
Take care to connect the correct cable. The connectors of this cable are housed in yellow insulation. Note that one end is marked To PLC and the other To Adapter; insert accordingly.
The module is supplied with a 1-meter cable, part number EXL-CAB100. Other cable lengths are also available.
Use only an original Unitronics cable and do not make any changes to it.

An adapter provides the interface between the OPLC and an expansion module. To connect the I/O module to the adapter or to another module:
1. Push the module-to-module connector into the port located on the right side of the device.
Note that there is a protective cap provided with the adapter. This cap covers the port of the final I/O module in the system.

Use crimp terminals for wiring; use 26-12AWG wire (0.13 mm 2 –3.31 mm2
) for all wiring purposes.
1. Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure that a proper connection can be made.
4. Tighten enough to keep the wire from pulling free.

To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m (5 kgf·cm).

Do not use tin, solder, or any other substance on stripped wire that might cause the wire strand to break.

Install at maximum distance from high-voltage cables and power equipment.

1. Connect the “positive” cable to the “+V” terminal, and the “negative” to the “0V” terminal.

Always connect the functional earth pin to the earth ground. Use a dedicated wire for this purpose; it must not exceed 1 meter.

Do not connect the neutral or line signal of the 110/220VAC to the device’s 0V pin.

In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the device to a regulated power supply.

A non-isolated power supply can be used provided that a 0V signal is connected to the chassis.

Note that both the OPLC and the EX-A2X must be connected to the same power supply.
The EX-A2X and the OPLC must be turned on and off simultaneously.
