Powering Up an IP-IO Module

You perform the following steps to power up an IP-IO module.

The IP-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.

A DIN rail is a common and convenient technique for installing the IP-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 IP-IO module rail and adjacent rails or other panel-mounted devices.

The IP-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.

The restrictions on installing the device in other orientations differ depending on the operating conditions.

Déclaration

CONTROLLER DEVICE DAMAGE

Follow the installation orientation restrictions that apply to the specific BACnet/IP device.

Failure to follow these instructions can result in equipment damage.

Under normal operating conditions of 0 to 50 °C (32 to 122 °F), the IP-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.

Installing the IP-IO module rotated 180 degrees from the horizontal position with device label text up and down (“e” in the figure), face down from a ceiling (“d” in the figure), or face up on a horizontal surface (“f” in the figure) is not supported.

When the IP-IO module is used for rooftop applications, -40 to +60 °C (-40 to +140 °F), the device should be installed horizontally, with the device label text in the upright position reading left to right. See “a” in the following figure. Any other installation orientation (“b”, “c”, “d”, “e”, and “f” in the figure) may exceed the IP-IO module's thermal specifications, which can damage the module.

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

Déclaration

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

The IP-IO module can be installed in a standard DIN enclosure/cabinet.

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

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.

Déclaration

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.

The IP-IO module is delivered with terminal blocks installed on the device.

The terminal blocks are removable. You can replace an IP-IO module in seconds because no terminal wiring is affected. The only exception is the high power relay output on the IP-IO-UIO5DOFA4 model, which uses a two-position fixed terminal block due to current requirements.

All IP-IO module models can be equipped with MP-C Display (part number SXWMPCDSP10001), which is an add-on module that enables manual override control of analog and digital outputs. The module consists of an LCD display and keys. The module is designed for permanent installation.

Déclaration

CONTROLLER DEVICE DAMAGE

Do not try to remove the MP-C Display module.

Failure to follow these instructions can result in equipment damage.

Do not try to remove the MP-C Display module as it may damage the enclosure and the module. Once installed, the MP-C Display module cannot be removed.

The IP-IO module has a built-in power supply designed to accommodate 24 VAC at 50/60 Hz or 24 to 30 VDC input power.

The built-in power supply is based on a half-wave rectified, non-isolated design, which is complemented with electronic protection components for transient protection, overload protection, and EMC compliance.

To power the IP-IO module, you can use a transformer or a DC power supply:

  • Class 2 (EN 60742) transformer supplying a nominal 24 VAC at 50/60 Hz

  • DC power supply supplying a nominal 24 to 30 VDC with the required output power

Pour plus d'informations, voir IP-IO Modules .

A separate, local 24 VAC step-down transformer is recommended to power each MP controller or IP-IO module. The transformer with appropriate VA rating may also be used to power the locally connected I/O devices. The separate transformer helps to avoid problems with ground loops, 24 VAC induced EMI on LAN, low or distorted AC voltage level at the controller, and excess transformer load due to the half-wave power supply, which can result in intermittent equipment detected faults, loss of communications, or equipment damage.

Déclaration

EQUIPMENT DAMAGE

Use a separate, local 24 VAC step-down transformer to power each MP controller or IP-IO module.

Failure to follow these instructions can result in equipment damage.

Déclaration

EQUIPMENT DAMAGE

Do not power the controller or I/O module with a 24 VAC transformer that is used to power devices that contain non-isolated full-wave rectifier power supplies.

Failure to follow these instructions can result in equipment damage.

Déclaration

EQUIPMENT DAMAGE

Ensure that the input power polarity is correct and that the voltage level meets the specifications of the IP-IO module.

Failure to follow these instructions can result in equipment damage.

Déclaration

EQUIPMENT DAMAGE

Do not connect 230 VAC or 110 VAC to any terminal.

Failure to follow these instructions can result in equipment damage.

Déclaration

EQUIPMENT DAMAGE

Ensure earth ground is properly connected to avoid damage to the device and to ensure proper operation of the device.

Failure to follow these instructions can result in equipment damage.

Déclaration

EQUIPMENT DAMAGE

Use a separate, local 24 VAC step-down transformer to power each MP controller or IP-IO module.

Failure to follow these instructions can result in equipment damage.

To power up an IP-IO module

  1. Check that all wiring is correct.

  2. Ensure that the 24 VAC at 50/60 Hz or 24-30 VDC power is supplied to terminals 1 and 2.
