Function

High-density AC output

It provides 16 AC output channels (2 groups, 8 points in each group), supporting 74-265V AC, and is suitable for controlling AC loads such as relays, solenoid valves, indicator lights or motor starters.

Each point supports a current of 0.5A, and the total current of the module can reach up to 4A (60°C).

Mechanical fuse protection

Each group is equipped with a mechanical fuse with a trigger current of approximately 2.5A, and the fuse status is reported by the tag "FuseBlown".

Support the "FieldPwrLoss" tag to detect power loss at the output point field.

Status control

Supports Fault Mode and Program Mode at each point, which can be configured as ON, OFF or remain in the final state (default OFF).

Support Scheduled Outputs, with a synchronization time of up to 16.7 seconds.

Diagnosis and Monitoring

The LED indicator light shows the output status, communication status, module health status and fuse status.

There is no advanced diagnostic function.

Network integration

Communicate with the ControlLogix controller via ControlNet or EtherNet/IP network, supporting local or distributed I/O architecture.

Supports hot plugging (RIUP), which is convenient for maintenance and replacement.

Software configuration:

Configured using the Studio 5000 Logix Designer software, it supports point-level configuration, communication formats (rack optimization, direct connection, scheduling output), and Add-On Profiles (AOP).

Application scenarios

Industrial automation control

Control AC equipment in the production line, such as relays, solenoid valves, indicator lights or small motor starters, suitable for manufacturing, automotive assembly and packaging systems.

Process control

In the petrochemical, power or water treatment industries, drive AC loads such as pumps, valves or alarm devices.

High channel density (16 points) is suitable for applications that require multiple output points.

Distributed control system: It is integrated into large-scale factory automation systems as a remote I/O component through ControlNet or EtherNet/IP networks.

General AC load control: Suitable for controlling alarms, buzzers or contactors, and widely used in factory automation.
