Product Introduction
The Allen Bradley 1732E-IB16M12R I/O Module is a distributed 24 V DC digital input module designed for EtherNet/IP-based industrial automation systems. It provides 16 sinking-type digital input channels, enabling reliable acquisition of field signals from sensors, switches, and other discrete devices.
This module is part of the ARMORBLOCK I/O family and features a dual-port EtherNet/IP interface with Device Level Ring (DLR) support for network redundancy. Its sealed housing with IP67/IP69K protection allows installation directly on machines, even in harsh or washdown environments. The use of M12 connectors simplifies wiring and enhances reliability in distributed I/O architectures.
