Function

High-density input

It provides 16 24V DC inputs. The single-slot design saves chassis space.

Supports passive/passive wiring and is compatible with various sensors (such as proximity switches and photoelectric sensors).

Reliable signal detection

Detect 10-30 V DC signals. An 8 ms delay is suitable for standard control applications.

8 mA current per point, optimizing power consumption.

Modular design

Compatible with the SLC 500 system and working in coordination with other I/O modules (such as 1746-IO12DC).

Supports hot plugging (operate with care) for easy maintenance.

Status indication:

Sixteen LED indicator lights show the on/off status of each input point, facilitating diagnosis.

Programming support: Interact with SLC processors (such as 1747-L531) through RSLogix 500 software configuration.

General application: Compatible with a variety of 24V DC devices and provides flexible input solutions.

Application scenarios

Manufacturing industry: Detect sensor signals on production lines (such as proximity switches, limit switches) for assembly or packaging systems.

Material handling: Monitor the sensor status of the conveyor belt or sorting system and manage the logistics process.

Food and Beverage: Detect the signals of filling or packaging equipment (such as bottle cap sensors) to ensure stable production.

Water treatment: Monitor liquid level, flow or pressure sensors and integrate them into the control system.

Building automation: Detect switch signals in HVAC systems (such as damper status).

OEM equipment: Integrated into dedicated machinery (such as testing equipment), providing high-density DC input.

Typical applications:

For small and medium-sized control systems, multiple 24 V DC signals need to be detected.

Standard industrial automation, used in conjunction with the SLC 500 system.
