IP-IO Module Built-in Power Supply

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

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.

Hinweis

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.

Hinweis

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.
