Function

Electronic fuse AC output

8 AC output channels (2 groups, 4 points in each group), supporting 74-132V AC, suitable for controlling AC loads (such as relays, solenoid valves, indicator lights).

Each electronic fuse protection point is triggered and automatically protected. It can be reset through software.

Status control

Support fault mode and program mode (ON/OFF/ keep final state).

Supports scheduling output, with a synchronization time of up to 16.7 seconds.

Diagnostic function:

It provides fuse status detection, LED indication output, communication, module health and fuse status.

There is no comprehensive diagnosis of 1756-OA8D (such as open circuit and load loss detection).

Network integration

Supports ControlNet or EtherNet/IP networks, suitable for local or distributed I/O.

Supports hot plugging (RIUP).

Software configuration:

Configured with Studio 5000, it supports point-level configuration, fuse Settings and communication formats (rack optimization, direct connection, scheduling output).

Application scenarios

Industrial automation: Controls AC equipment in production lines, such as solenoid valves, relays, and indicator lights, and is applicable to manufacturing, automotive assembly, and packaging.

Process control: Drive AC loads (such as pumps and valves) in petrochemical, power, and water treatment industries. Electronic fuses reduce downtime.

Distributed control: Integrated into large-scale factory automation systems, suitable for cross-regional control.

High-reliability scenarios: Electronic fuse protection is suitable for continuous production or critical load control.

General-purpose AC loads: Control alarms, buzzers, contactors, widely used in factory automation.
