POINTBus Capacity
Features:
- Extends POINTBus power for four to seventeen I/O modules, depending on current demand.
- Creates a new field-power partition for downstream POINT I/O modules.
- Supports 10 to 28.8 V DC input with orientation-dependent POINTBus output current.
1734-EP24DC passes field power to the I/O modules on its right, regenerates 5 V system power and separates the downstream field-power bus from modules on its left. Horizontal mounting supports 1 A at 10 to 19.2 V input and 1.3 A at 19.2 to 28.8 V; vertical mounting supports 1 A across the full range.
Before replacement, record module order, power-segment boundaries, terminal wiring, polarity, adapter type and calculated POINTBus load. After installation, verify both green status indicators and confirm normal operation of every downstream module and field circuit.
The 1734-EP24DC Allen-Bradley Expansion Power Supply is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.

1734-EP24DC regenerates POINTBus power and begins a new field-power segment for modules to its right. The field-power bus is rated to 10 A maximum, while usable POINTBus output current depends on supply voltage and mounting orientation.
Mount the power supply on the DIN rail between POINT I/O modules, engage both side interlocks and use only 12/24 V DC wiring. Terminals 6 and 7 are +V DC, terminals 4 and 5 are common and terminals 2 and 3 are chassis ground.
The supply supports four to seventeen downstream modules according to individual current ratings. A full POINT I/O system may use multiple expansion supplies, but scanner capacity, module count, voltage derating and field-power segmentation must all remain within the documented limits.
