FAQs

  • What is the 1746-P2?+
    The Allen-Bradley 1746-P2 is a legacy, rack-mounted power supply for SLC 500 PLC systems, providing 5V DC (5A) and 24V DC (0.96A) power.
  • What are the input voltage settings for 1746-P2?+
    It supports dual voltage operation: 85–132V AC or 170–265V AC (47–63 Hz).
  • How do I configure the input voltage?+
    A jumper wire loop located near the AC input terminal block on the circuit board must be configured for either 120V or 220V operation.
  • Can the 1746-P2 replace a 1746-P1?+
    Yes, it is a direct replacement. The 1746-P2 provides higher output current (5A vs 3.6A at 5V).
  • Can I wire more than one cable per terminal?+
    Yes, the terminal block allows a maximum of two AWG wires per terminal.

Features:

  • SLC 500 controllers
  • 5V DC @ 5A + 24V DC @ 0.96A
  • 120 to 220 Volts AC
The Allen-Bradley 1746-P2 is an SLC 500 modular power supply. It comes with an input voltage of 85-132 or 170-265V AC at 47-63 Hz. Its internal current capacity at 5V is 5 A and it is 0.96 A at 24V. This power supply also comes with a maximum user-supplied overcurrent protection of 15 A and a maximum inrush current of 20 A.It has a 180 VA typical line power requirement and an input terminal and backplane isolation of 1800V AC RMS for 1 s. User-power current capacity at 24V DC is 200 mA and the user-power voltage range of the power supply, also at 24V DC, is 18-30V DC.

It has a maximum of two AWG wires per terminal. Fuse protection is present with the 1746-P2 power supply but it is limited to guarding against fire hazards due to short-circuit conditions. It comes with an open-type enclosure and can only be installed in a 1746 chassis. The entire power supply measures 5.5 x 2.9 x 5.7 inches and weighs 1.1 kg or 2.5 lbs. Its operating temperature is from 0-60 Deg. Celsius. This power supply module has a jumper terminal that is used to set the input voltage to be applied to the device.

The 1746-P2 Allen-Bradley Power supply may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

SLC 500 controllers continue to operate (hold-up) for a short period of time if theinput voltage to the power supply drops below the recommended operatingvoltage range. The controller continues to scan the user program and control I/Oduring this time. CPU hold-up for each power supply is shown on pages 14 and 16.SLC 500 controllers turn OFF (stop scanning and disable outputs) if input voltage tothe power supply is removed or drops below the recommended operating rangefor a period exceeding the CPU hold-up time. The controller resumes operationautomatically when the input voltage is restored to normal.If the input voltage to the 1746-P7 power supply falls into a range of 4 to 9V for aperiod exceeding the CPU hold-up time, the controller turns OFF and will not turnback ON until input voltage is increased to 11V dc.
  • Automotive Plants: Used in stamping & body shops with robotic welders and presses.
  • Food & Beverage Facilities: 20ms hold-up time prevents power sags from ruining batches.
  • Pharmaceutical Factories: Reliable for autoclaves & centrifuges in regulated cleanroom environments.
  • Water & Wastewater Treatment:120/240V AC flexibility for remote pumping stations without complex conditioning.

Chassis Placement: It must be installed in the leftmost slot of the 1746 chassis.
Voltage Selection: You must manually set the jumper for either 120V or 240V AC input before applying power to avoid damaging the unit.
Grounding: Proper grounding to the chassis ground terminal is required to minimize electrical noise, which can interfere with the PLC's logic instructions.
