ABB Pb PN-112718 Digital Input Module

The ABB Pb PN-112718 (order number 4002918771, also referenced as PN-112716) is a 16‑channel digital input module for industrial automation systems. It is designed for reliable signal acquisition from sensors, limit switches, pushbuttons, and other 24 V DC field devices in harsh industrial environments. The module supports PROFINET communication and can be used as a remote I/O station in distributed control architectures.

16 Digital Input Channels

The module provides 16 independent digital input channels, each accepting 24 V DC signals from field devices. The inputs are compatible with both sink and source wiring configurations and meet the type 3 characteristics of IEC 61131‑2, ensuring reliable detection of sensor signals even with long cable runs.

PROFINET Communication

The integrated PROFINET interface enables the module to act as an IO device on a PROFINET network. It can be connected to a PROFINET controller (e.g., SIMATIC S7‑1200/1500) and exchange I/O data in real time. The module supports standard PROFINET functions such as device replacement without programming (LLDP) and diagnostic alarms.

IP67 Protection for Harsh Environments

With an IP67 rating, the module is dust‑tight and can be immersed in water up to 1 metre depth for 30 minutes. This allows direct machine‑mounting without a control cabinet, reducing cabling and installation costs. The wide -25°C to +70°C operating temperature range makes it suitable for outdoor and unheated industrial facilities.

Application Domains

The module is ideal for use as distributed I/O on packaging machines, conveyor systems, assembly lines, and in process automation where sensors are spread over a large area.
