Overview

The WEIDMULLER RM16DIHW (P/N 1047760000) is a 16-channel Digital Input (DI) Module for modular Remote I/O or PLC/DCS systems. It efficiently collects discrete signals from field devices such as limit switches, proximity sensors, pushbuttons, and auxiliary contacts. The "HW" denotes a High-Density Wiring configuration, allowing maximum channel count in minimal space. This module ensures reliable status monitoring and fast response in automated processes.

Technical Data

Typical Applications

• Automated Production Lines: Collects signals from sensors, light curtains, and E-stop buttons for conveyor and assembly control.

• Packaging & Material Handling: Monitors pneumatic clamps, grippers, and indexing devices, feeding real-time data to the PLC.

• Building Automation (BMS): Aggregates contacts from fire/smoke detectors, door sensors, and HVAC alarms.

• Electrical Switchgear/Substations: Monitors auxiliary contacts or relay statuses for system awareness.

Benefit: Reduces wiring length to the main control panel, cutting installation time and cost in large, distributed systems.

FAQ

Q1: What is the benefit of a "High-Density" module?
A1: Packs more channels into a smaller space, lowering enclosure size, cost per channel, and required backplane/mounting hardware.

Q2: Does this module require separate field power?
A2: Yes, 24 VDC is required for the sensors and switches. The module itself draws power from the system backplane, ensuring isolation from field devices.

Q3: What does "Sourcing or Sinking" mean?
A3: "Sourcing" supplies current to the field device; "Sinking" receives current from the device. Most industrial 24 VDC inputs are sinking. Always confirm configuration before connecting sensors.
