Overview

The WEIDMULLER RM16DOHW (P/N 1047770000) is a 16-channel Digital Output (DO) Module for modular Remote I/O systems. It provides precise ON/OFF control of actuators and indicators such as relays, solenoid valves, pilot lamps, and contactors. The "HW" denotes High-Density Wiring, optimizing DIN rail space for compact installations. This module ensures timely, coordinated actuation and reliable operation in automated processes, with each output protected against short circuits and overloads.

Technical Data

Typical Applications

• Conveyor & Sortation Systems: Activates solenoid valves for cylinders controlling stops, clamps, and package diverters.

• Process Control Valve Actuation: Drives relays or motorized valve/damper actuators in flow and fluid systems.

• Indicator & Signaling Systems: Controls pilot lamps, horns, and stack lights to provide visual/audible feedback.

• Packaging Machinery: Manages multiple small actuators, clutches, and brakes in high-speed filling, labeling, and sealing lines.

Benefit: Electronic short-circuit protection on each channel prevents a single fault from affecting the entire module, reducing downtime and maintenance.

FAQ

Q1: What does "Sourcing/High-Side Switch" mean?
A1: When ON, the module connects the load to the positive (+24 VDC) supply. The negative return of the load connects to 0 VDC, simplifying field wiring.

Q2: Can it switch large motors or powerful solenoids directly?
A2: No, each channel is limited to 0.5 A. High-current devices should be controlled via intermediate relays or contactors.

Q3: What is the role of the backplane?
A3: The backplane provides mechanical support, distributes the system bus between the module and controller, and supplies operating power (typically 5 VDC logic) to the module.
