Reliable Multi-Channel OutputThe 1746-OB16E delivers up to 16 independent, sourcing digital outputs, each rated for 0.5A at 30V DC. Its positive logic solid-state design ensures fast, reliable switching for a wide range of industrial automation applications. With built-in status LEDs, engineers and technicians can quickly diagnose output status, streamlining maintenance and troubleshooting.
Engineered for Industrial DemandsDesigned specifically for SLC 500 PLC systems, the 1746-OB16E module features robust isolation with 1500V AC RMS between logic and field sides, and can function in harsh environments-ranging from 0C to 60C. Compact dimensions and module rack mount compatibility allow for easy integration into both new and existing control panels.
Flexible and Easy IntegrationThis digital output module is suited for various industrial applications, from operating solenoids and relays to controlling indicator lamps. Its compatibility with the SLC 500 chassis and standard field wiring arm (1746-W16) provides installation flexibility. Both new and used units are available, supported by a worldwide supplier network.
FAQ's of ALLEN BRADLEY 1746-OB16E 16-Channel Digital DC Source Output Module:
Q: How do I install the Allen Bradley 1746-OB16E module into my PLC system?
A: To install the 1746-OB16E, insert it into an available slot in your SLC 500 chassis and secure it properly. Ensure you use the compatible 1746-W16 wiring arm for field connections (sold separately). Once installed, wire your output devices according to the module's terminal layout.
Q: What devices can I control with this 16-channel DC source output module?
A: This module is designed to control a range of DC-powered devices, including solenoids, relays, lamps, and other actuators commonly found in industrial automation and control systems.
Q: What is the benefit of solid-state sourcing outputs in the 1746-OB16E?
A: Solid-state sourcing outputs provide faster switching speeds, longer lifespan (no mechanical wear), and reduced maintenance compared to mechanical relays. Positive logic (sourcing) also simplifies wiring for many industrial applications.
Q: What is the maximum current I can draw from each output and the entire module?
A: Each output channel can source up to 0.5A at 30V DC, with a module total of 8A. Short duration surges up to 2A per output (for max. 10ms) are supported for transient loads.
Q: How does the module indicate output status?
A: Each output channel on the 1746-OB16E is equipped with an LED indicator. When a channel is active, the corresponding LED will be illuminated, making it easy to check the real-time status of all outputs.
Q: Where can this module be used and what temperatures does it support?
A: The 1746-OB16E is suitable for industrial environments and can operate within a temperature range of 0C to 60C (32F to 140F), with storage capabilities from -40C to 85C.
Q: Is the 1746-OB16E compatible with existing SLC 500 systems?
A: Yes, the 1746-OB16E is fully compatible with Allen Bradley SLC 500 series PLCs and fits into any standard SLC 500 I/O chassis, making it an excellent replacement or expansion module.
