The Allen-Bradley 1734-EP24DC is a POINT I/O Expansion Power Supply. It passes the 24V DC electric field to the I/O module on the right side. This power supply expansion unit extends the backplane bus power up to 17 I/O modules on the right side of the supply. This power supply creates a new field voltage partition segment for the field drive device. The 1734-EP24DC separates field power from the I/O module to the left of the unit.

You can use a power supply expansion unit with a POINT I/O adapter to assemble the system in full. The 1734-EP24DC expansion unit is compatible with 1734 POINT I/O adapters. It is mainly used to extend the POINTBus current and supply power to modules installed at the right side of the power supply.

Here are the technical specifications for the Allen Bradley PLC POINT Power Supply Extension Module 1734-EP24DC:

  • Module Type: Expansion Power Supply
  • Supply Voltage Range: 10-28.8V DC
  • Inrush Current: 6 amps for 10 milliseconds
  • Overvoltage Protection: Reverse Polarity
  • Power Supply Current: 10 amps
  • Field Power: 24 Volts DC
  • Operating Vibration:5g
  • Operating Shock: 30g
  • Nonoperating Shock: 50g
  • Mounting: Horizontal / Vertical
  • Temperature: -13-140℃ ( -40-185℉)

The 1734-EP24DC supports installation of up to Four (4) to Seventeen (17) POINT I/O modules, depending on the current rating of the installed module. It has an input voltage rating of 24VDC, nominal with acceptable voltage range of 10-28.8 VDC. This expansion power supply is capable of withstanding an inrush current of 6 Amperes for 10 ms.

The 1734-EP24DC has a built-in status indicator such as field power status indicator and 5V system power indicator.

It may be installed horizontally and vertically, following the orientation of the POINT I/O system.
When installed horizontally, the POINTBus output current are 1 A @ 10-19.2VDC input and 1.3 A @ 19.2-28.8VDC input.
When installed vertically, the POINTBus output current is 1 A @ 10-28.8V input.

This module has an integral input overvoltage protection, specifically, reverse polarity protection.

The 1734-EP24DC is compatible for installation with any 1734 POINT I/O adapters. When the expansion power supply is interrupted, the output voltage stays within the specification when input supply voltage drops out for 10 ms at 10V maximum load.

The 1734-EP24DC has a maximum power consumption of 9.8 W @ 28.8V DC and maximum power dissipation of 3.0 W @ 28.8V DC and Thermal Dissipation of 10.0 BTU/hr @ 28.8V DC.
