FAQs
-
What is the 1746-OB16？+The Allen-Bradley 1746-OB16 is a 16-point DC digital output module for the SLC 500 programmable controller family. It is a sourcing output module, commonly used to switch 10-50V DC loads
-
How does the electronic protection work?+The 1746-OB16 features electronic protection against short circuits and overloads based on a thermal cut-out principle, which limits the current on a channel. It features auto-reset capability.
-
Does it have internal fusing for protection?+No, the 1746-OB16 has no internal fuse. External fusing is required to protect the module from short circuits or overloads.
-
What is the operating voltage of 1746-OB16?+In some specifications, its operating voltage is 10-50V DC or 10-30V DC.
-
What does the E-Fuse LED indicate?+The "E-Fuse" LED on the front panel lights up when an overload or short circuit condition is detected, indicating that the module is currently limiting the current on one or more outputs.

Features:
- SLC 500 series
- 24V DC for signal output
- Electronically Protected Module
The 1746-OB16 output module, part of Allen Bradley's SLC 500 series, excels in facilitating automated control systems. With a total of 16 outputs grouped together for streamlined functionality, this module is rated for a 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 in various applications.
The 1746-OB16 Allen Bradley I/O Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
In terms of performance, the module has a heat dissipation rating of 0.388 watts per individual output point, accumulating to a total output heat dissipation of 7.6 watts across the module. It has a minimum heat dissipation requirement of 1.4 watts, ensuring appropriate thermal management during operation.
Backplane current consumption is specified at 0.28 Amps when operating at 5V DC, with no current draw at 24V DC. When it comes to response times, users can expect a 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.

The Allen-Bradley 1746-OB16 and 1746-OB16E are both 16-channel, current-sourcing DC output modules designed for the SLC 500 programmable controller platform. The primary distinction lies in their protection mechanisms: the 1746-OB16E provides enhanced electronic protection against short circuits and overloads, while the 1746-OB16 is a standard electronic module.
Module Type: Both are 16-channel sinking/sourcing (sourcing output) DC modules.
Protection:
1746-OB16E: Features electronic protection that detects short-circuit and overload conditions, designed to protect the module from damage.
1746-OB16: Standard electronic output module.
Voltage: Both typically operate within a range suitable for 24V DC systems.
Compatibility: Both use the same 1746 chassis and wiring, often with color-coded removable terminal blocks.
