UN 322-1HH01-0AA0 Unimat – relay digital output module SM322, 16DO relay, 2 A, UN300

UN 322-1HH01-0AA0 is a relay output module of the UN300 series with 16 outputs and a rated current of 2 A. It is a component of the series UniMAT UN300 designed for industrial control systems, machine modernisation, switchboards and distributed I/O assemblies.

The product is suitable for switching electrically isolated loads, contactors, relays and other actuators where a relay output is suitable. When choosing, it is important to compare the full order number, number of channels, signal type, supply, connector and the parameters of the specific PLC project.

Typical applications

Switching electrically isolated loads, contactors, relays and other actuators where a relay output is suitable. The module can be used when building a new control system as well as when servicing and modernising existing automation, provided the electrical and system parameters meet the application requirements.

Technical specifications

Wiring and integration into the PLC assembly

Relay outputs require checking the voltage and current of the connected load as well as the type of load (resistive / inductive). The signal connection is made via a 20-pin front connector; verify the exact terminal layout in the manufacturer's wiring diagram.

Compatibility and choosing a replacement

The manufacturer lists SM322 16DO Relay 2 A as a relay output variant in the UN300 series for S7-300. architecture systems

When replacing an existing module, a similar name is not enough. Compare the full order number, number and type of I/O, voltage and current levels, resolution, connector, wiring, parameterisation and support in the PLC configuration used.

Frequently asked questions

Co je UN 322-1HH01-0AA0?

This is a relay digital output module SM322 of the UniMAT UN300 series in the version 16DO relay, 2 A.

Where is this module used?

Typically for switching electrically isolated loads, contactors, relays and other actuators where a relay output is suitable.

What to watch out for when wiring?

Before connecting, verify the voltage, current and type of load. The total group current and the protection method of the output circuit are also important.

How do I verify the correct variant?

Compare the full order number UN 322-1HH01-0AA0, number of channels, signal type, supply, connector and PLC configuration. If any of these data differ, the replacement cannot be confirmed just by the appearance or name of the module.
