Description

​330180-51-RU | 16-Channel Digital Input Module – Replacement Unit​​

​​Product Code:​​ 330180-51-RU
The 330180-51-RU is a high-density ​​16-channel digital input module​​ designed as a direct ​​Replacement Unit (RU)​​ for industrial programmable logic controller (PLC) systems. This module serves as the critical interface between field devices (like sensors, switches, and push buttons) and the central processing unit of the control system. The “-RU” suffix guarantees that this unit is a form-fit-function equivalent to the original manufacturer’s part, enabling fast and reliable maintenance to minimize system downtime.

​​Key Features​​

  • ​​High-Density Design:​​ Provides 16 isolated digital input channels on a single module, optimizing space within the PLC rack.
  • ​​Sinking/Sourcing Configurable:​​ Typically supports both sinking (PNP) and sourcing (NPN) input field devices, offering wiring flexibility for various applications.
  • ​​LED Channel Status Indicators:​​ Each channel features a bright LED to provide instant visual confirmation of the input status (ON/OFF), drastically simplifying diagnostics and troubleshooting.
  • ​​Opto-isolation:​​ Channels are opto-isolated from the control system’s backplane to protect the PLC from voltage spikes, electrical noise, and ground loops present in the field wiring.
  • ​​Wide Input Voltage Range:​​ Compatible with standard industrial control voltages, typically 24V DC.
  • ​​Plug-and-Play Replacement:​​ Designed for direct swap-out with the original module, requiring no hardware or software reconfiguration when replacing a like-for-like failed unit.
