Function

Hybrid I/O design: It provides 4 120V AC inputs and 4 relay outputs, supporting AC/DC hybrid loads and suitable for various control requirements.

Status indication: The front panel LED displays the status of each I/O point, facilitating monitoring and fault diagnosis.

Flexible installation: It can be installed in any slot of the SLC 500 rack (except slot 0), and supports modular expansion.

Relay output: Supports wide-range output (5-265V AC, 5-125V DC), compatible with various device loads.

High reliability: Industrial-grade design, CSA Class I, Division 2 certification, suitable for harsh environments.

Application scenarios

Factory automation: Used in production lines (such as automobiles, packaging), actuators that connect 120V AC sensors/switches and relay controls.

Process control: In water treatment or light industry, it monitors AC input signals and controls equipment such as pumps and valves.

Distributed control: As part of the SLC 500 system, integrated into the remote I/O network, it is suitable for distributed factory layouts.

Equipment renovation: It is used to upgrade the old PLC system and be compatible with traditional AC input and relay output devices.

General control: Controls lighting, heaters or other low-power loads, suitable for small and medium-sized industrial applications.
