When Downtime Strikes, Every Minute Counts
A failed output module can halt an entire production line. The Allen-Bradley 1746-OB32E keeps your SLC 500 system running with 32 electronically protected 24VDC outputs. This digital DC output module delivers high-current switching for demanding industrial loads. Oil AutoTech supplies ready-to-ship spares for oil, gas and automation applications.
What the 1746-OB32E Delivers
The 1746-OB32E is a SLC 500 Digital DC Output Module from Allen-Bradley. It provides Thirty-Two (32) 24VDC, electronically protected output channels. Two input groups each contain Sixteen (16) points, giving you flexible wiring across your panel. You can install this module in either SLC 500 fixed or modular style hardware.
Key Specifications at a Glance
The 1746-OB32E operates across a 10-30 Volts DC range with a nominal output of 24VDC. Each output handles 0.5 or 0.25 amps, while the module supports up to 8 amps total. Backplane current draw is just 190 milliamps at 5 Volts. Step response is 60 milliseconds in and 2.5 milliseconds out. Signal delay is 0.1 ms ON and 1.0 ms OFF.
Electronic protection sets this module apart. When overload or short circuit conditions occur, the affected channel limits current within milliseconds. Other channels continue operating normally thanks to individual detection capability. The module auto-resets after the thermal cut-out clears. Note that if the command was ON, the load turns ON again after recovery. Plan your safe operation state accordingly.
Built for Harsh Industrial Environments
The 1746-OB32E handles operating temperatures from -13 to 140 degrees Fahrenheit. Nonoperating range extends from -40 to 185 degrees Fahrenheit. Relative humidity of 5-95% noncondensing suits most plant environments. The module withstands 2g vibration at 10-500 Hz and 2.5g at 57-2000 Hz. Operating shock tolerance reaches 30g.
Color-coded removable terminal blocks simplify wiring. Each terminal accepts two 14 AWG (2 mm2) cables with a self-lifting plate. LED indicators on the front show output point status. Route input power separately from I/O device cables to reduce electrical noise.
Where This Module Fits
Oil and gas facilities rely on the 1746-OB32E for valve control, pump starters and alarm annunciation. Manufacturing plants use it for solenoid drivers, indicator lamps and relay coils. The high-current capability handles loads that standard output modules cannot. Water treatment operations deploy it for motor control and process interlocking.
Integration and Compatibility
The 1746-OB32E works within SLC 500 fixed or modular hardware configurations. It functions similarly to the 1746-OB32, but adds integral electronic protection. Remember that electronic protection is not equivalent to an external electronic fuse. Proper external protection may still be necessary and recommended for your installation. Reverse polarity and improper signal source wiring error protection is not included.
Selection Checklist Before You Buy
Verify your system uses SLC 500 hardware. Confirm your load voltage falls within the 10-30 Volts DC range. Check that total current demand stays below 8 amps per module. Count your output points to ensure 32 channels meet your needs. Consider whether auto-reset behavior after overload suits your safety requirements. Oil AutoTech offers hands-on technical selection help for these decisions.
