1734-EPAC Allen-Bradley POINT I/O Expansion Power Supply

Allen-Bradley 1734-EPAC POINT I/O Expansion Power Supply

Key Technical Specifications

• The 1734-EPAC accepts a wide field power input of 120 V AC or 240 V AC (85–264 V AC range). It consumes 15.1 W maximum and dissipates 8.4 W at 264 V AC.
• Inrush current is limited to 2 A for only 6 ms, reducing stress on upstream components. Built-in MOV and fuse provide robust overvoltage protection.
• This unit supplies a total of 10 A of field-side current to the modules. It also offers 264 V continuous isolation voltage, tested to 3250 V DC for 60 seconds.
• Two green LEDs clearly indicate field power status and 5 V system power. Thermal dissipation measures 28.7 BTU/hour.
• Operating temperature range reaches 55 °C (131 °F) with 95% non‑condensing humidity. Certifications include cULus, CE, and C-Tick.

Frequently Asked Questions (FAQ)

• What is the maximum number of I/O modules a 1734-EPAC can support?
  The exact count depends on the current draw of each module, but it typically supports 4 to 17 POINT I/O modules on the DIN rail.
• Can I use 1734-EPAC with both 120 V and 240 V AC systems?
  Yes, the 1734-EPAC accepts nominal voltages of 120 V AC or 240 V AC (85–264 V AC range) at 50/60 Hz.
• Does this power supply include overvoltage protection?
  Absolutely, it features both a metal-oxide varistor (MOV) and an internal fuse for input overvoltage protection.
• What do the two green LEDs indicate?
  One LED shows field power status; the other indicates that 5 V DC system power is present.
• Is the 1734-EPAC a new original part?
  Yes, we supply only brand-new, authentic Allen‑Bradley modules with full manufacturer warranty support.
