Wiring a Screw Terminal on an RP-IO Module

You wire the screw terminals on the RP-IO module to connect I/O devices and power. Always use the recommended wires (or wires with larger cross-sectional area).

The RP-IO module can be installed on a DIN rail or other flat surface inside a cabinet. The device is recommended to be installed in a cabinet, unless local regulations allow an exception.

Installation orientations

Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the RP-IO module can be installed in the following orientations:

  • Horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right. See “a” in the following figure.

  • Vertically (on a DIN rail going from top to bottom), which means that the device is rotated +90 degrees or -90 degrees from the horizontal position. See “b” and “c” in the following figure.

  • Face down from a ceiling. See “d” in the following figure.

  • Up and down, which means that the device is rotated 180 degrees from the horizontal position and with the device label text up and down. See “e” in the following figure.

  • Face up on a horizontal surface. See “f” in the following figure.

Installation on a DIN rail

A DIN rail is a common and convenient technique for installing the RP-IO module along with other associated control and monitoring devices. The most efficient ventilation is achieved with the wall-mounted DIN rail oriented horizontally and with adequate space provided between the RP-IO rail and adjacent rails or other devices.

The RP-IO module is typically installed horizontally (on a DIN rail going from left to right), with the device label text in the upright position reading left to right.

DIN rail end clip

To help prevent the device from sliding down or sideways on the DIN rail, install an end clip for DIN 35 (part number SXWDINEND10001) tightly against the bottom or rightmost device on the rail. The end clip is easily removed if you bend the snap lock open with a screwdriver.

Aviso

EQUIPMENT DAMAGE

Use an end clip (part number SXWDINEND10001) when you install the device on a vertical DIN rail.

Failure to follow these instructions can result in equipment damage.

Installation in a cabinet

All RP-IO module models are recommended to be installed in a cabinet, unless local regulations allow an exception.

Aviso

The device should be installed within an enclosure such as a control cabinet for isolation to exposed live parts.

When installing RP-IO modules in a cabinet, it is recommended to provide ample space between the DIN rails and modules for sufficient ventilation.

Screw terminals

The RP-IO modules have fixed screw terminals. Para obtener más información, consulte RP-IO Screw Terminals .

Anchor points for cable ties

The RP-IO modules have four anchor points that can be used to fasten cable ties or other accessories for bundling wires.

Optional covers

The RP-IO modules can be equipped with optional covers to reduce access to the screw terminals and wires if desired.

The wiring recommendations provide guidance regarding wiring of the Central IO modules, automation servers, RP and MP controllers, IP-IO and RP-IO modules, RP controller expansion modules, and Operator Display.

I/O Wiring

The I/O wiring recommendations provide guidance on what type of wires should be used for the different Central IO modules, AS-B server onboard I/O, RP and MP controller onboard I/O, and IP-IO and RP-IO I/O modules, how to perform grounding, and how to connect different external devices to the inputs and outputs. This section also provides information on the external connectors required for the RP controller expansion modules and the RP-C-16C-F-230V model. Always use the recommended cables and wires.

Communication Port Wiring

The wiring recommendations for the communication ports on the automation servers, RP and MP controllers, IP-IO and RP-IO modules, RP controller expansion modules, and Operator Display devices apply to wires and cables used for RS-485 communications, LonWorks communications, USB connections, Ethernet connections, sensor bus connections, room bus connections, and RP and MP controller Modbus network connections. Always use the recommended cables and wires.

To wire a screw terminal on an RP-IO Module

  1. Loosen the screw of the terminal.

  2. Strip approximately 7 mm (0.3 inch) of the insulation from the end of each wire.

  3. Insert the end of the wire fully into its intended terminal. Ensure that no bare wire strands extend from the terminal.

  4. Tighten the screw using a small flat-blade screwdriver. Ensure that the screw is fully tightened. Use the following recommended screw tightening torque: 0.56 to 0.79 Nm (5 to 7 lbf.in).

  5. Use appropriate cable strain relief methods, especially for wires that carry 30 VAC or 42.4 VDC or above, to help prevent any load applied to the cable from being transferred to conductor terminations.

    You can use the anchor points on the RP-IO module enclosure and cable ties to fasten and fix the cables.
