1734-IB8 POINT I/O 8-Channel 24V DC Sink Digital Input Module for PLC Remote I/O System

The 1734-IB8 is an 8-channel digital DC input module from the POINT I/O 1734 series. It is designed for compact industrial control systems that require flexible and reliable remote I/O expansion. As a 24V DC sink input module, the 1734-IB8 is suitable for collecting signals from field devices such as proximity sensors, limit switches, push buttons, machine status contacts, photoelectric sensors, and other discrete input devices used in automated production lines.

This module is commonly used in PLC-controlled machinery, distributed I/O cabinets, packaging equipment, material handling systems, assembly machines, CNC auxiliary control panels, and general factory automation applications. Its compact modular design helps reduce control cabinet space while allowing maintenance engineers to build or repair I/O stations according to the actual number of input and output points required by the machine.

The 1734-IB8 supports 8 digital input points with a nominal 24V DC input and an operating input voltage range of 10–28.8V DC. It is installed on a compatible POINT I/O terminal base and mounted on a DIN rail as part of a modular I/O station. This structure makes it convenient for both new control panel projects and maintenance replacement of existing distributed I/O installations.

For maintenance teams and automation spare parts buyers, the 1734-IB8 is often selected when an existing input module fails, when additional sensor input points are required, or when a machine retrofit needs a compact remote input solution. Before replacement, users should confirm the module model, wiring type, terminal base, field device voltage, and communication adapter used in the original I/O station.

We can help customers confirm the correct POINT I/O module based on the machine nameplate, existing module photo, PLC system configuration, or spare parts list. Related models such as 1734-IB4, 1734-IB4D, 1734-IV8, 1734-OB8, 1734-TB, 1734-TBS, and 1734-AENT can also be supplied depending on the system requirement.

If you are replacing a damaged 1734-IB8 module or building spare parts inventory for factory maintenance, please send the full model number, required quantity, and product condition requirement. We can provide a fast quotation and help check compatible POINT I/O parts for your automation system.
