Equipped with a removable terminal block as standard
16 discrete outputs grouped together save control cabinet space and streamline functionality
The Allen Bradley SLC 500 is a small chassis-based family of programmable controllers, discrete, analog, and specialty I/O, and peripheral devices. The SLC 500 family delivers power and flexibility with a wide range of communication configurations, features, and memory options.
The RSLogix 500 ladder logic programming package provides flexible editors, point-and-click I/O configuration, and a powerful database editor. As an essential component within this hardware ecosystem, the 1746-OB16 output module excels in facilitating automated control systems. With a total of 16 outputs grouped together for streamlined functionality, this module is rated for a nominal voltage of 24V DC, ensuring compatibility with many signal output requirements. The operational voltage range extends from 10V to a maximum of 50V DC, providing flexibility across various industrial applications.
When it comes to response times, users can expect a rapid signal delay of 0.1 milliseconds when switching on and 1 ms for switch-off under maximum resistive load conditions. The maximum off-state leakage is recorded at 1 mA, while the module requires a minimum load current of 1 mA. Additionally, the maximum voltage drop in the on-state is limited to 1.2 volts when subjected to a current of 0.5 Amps. Surge capability is rated at 3 Amps for a duration of 10 milliseconds per output, making the module highly suitable for handling transient electrical conditions.
For ease of installation and wiring, the module is equipped with a removable terminal block, facilitating accessible connections and simplified field maintenance. Overall, the 1746-OB16 output module combines reliable performance with essential features, ensuring robust operation in a variety of automation environments.

Automotive
In body welding and assembly stations, the module's 16 output channels are used to precisely sequence the solenoid valves of pneumatic clamps and directly drive multi-color stack status lights on the operator console.
Food & Beverage
On aseptic filling lines, it controls miniature solenoid valves to precisely time the opening of liquid filling nozzles, while driving spray contactors and system fault buzzers at the washing station.
Machine Tools
In CNC machines, it energizes AC contactors for the spindle coolant pump and activates air purge valves and mechanical locating pins within the automatic tool changer (ATC) mechanism.
Lithium Battery
In electrode stacking or cell winding machines, it controls high-frequency precision pneumatic chuck solenoids to ensure instantaneous tensioning and locking of aluminum or copper foil electrode sheets.
Semiconductor
In back-end chip testing and taping machines, the module's 3 A surge capability is used to safely drive vacuum-breaking valves for high-frequency suction cups, achieving high-speed chip pick-and-place.
Metallurgy
In the post-processing stages of cold or hot rolling steel wires/plates, it drives electromagnetic directional valves for steel coil strappers, hydraulic pushers, and edge-trimming auxiliary mechanisms.
When using the 1746-OB16 module, you need to keep several key points in mind. It provides sourcing outputs, which means that the other side of your load must be tied directly to DC Common. The maximum current limit is 0.5A per channel and the total combined current for the entire module must not exceed 8.0A, so overloading is strictly prohibited. For inductive loads such as solenoid valves and relays, you must install external suppression diodes to suppress back-EMF and prevent internal transistor burnout. Finally, never hot-swap the module while the power is on, and routinely check the terminal block wiring to avoid loose connections.
The Allen Bradley 1746-OB16 serves as a 16-channel discrete DC output unit within the SLC 500 platform. Operating on a sourcing configuration, it accommodates external loads across a 10–50V DC voltage window while drawing 280 mA from the 5V backplane.
The 1746-OB16 has Sixteen (16) 24VDC output channels without individual isolation.
What is the operating output voltage range of the 1746-OB16?
The 1746-OB16 has an output voltage range of 10-5-VDC, sourcing.
