Product features

The Allen Bradley 1734-EP24DC is a high-quality expansion power module from the POINT I/O series, proudly designed and manufactured by Rockwell Automation's reputable Allen-Bradley brand. The Allen Bradley 1734-EP24DC has a nominal input voltage of 24V DC and supports a flexible input range of 10V to 28.8V DC to accommodate various power supply circumstances. It has a maximum input current of 400mA at 24V DC and can withstand a surge current of 6A for 10ms, as well as reverse polarity protection to prevent damage caused by faulty wiring. The module outputs a constant 5V DC power to the POINTBus, with output current varied slightly per installation: 1A to 1.3A for horizontal mounting (depending on input voltage) and 1A for vertical placement. This ensures sufficient power for connecting 4 to 17 I/O modules, depending on each module's current requirements.

The Allen Bradley 1734-EP24DC is lightweight and tiny, measuring 76.2×25.4×133.4mm (3.0×1.0×5.25 inches) and weighing only 120g (4.3 ounces). It may be easily installed on DIN rails in control cabinets. The module can operate in temperatures ranging from -20°C to 55°C (-13°F to 131°F) and relative humidity levels of 5% to 95% without condensation, ensuring longevity in tough industrial environments. It can withstand vibrations up to 5g (10~500Hz) and shocks up to 30g, making it reliable in tough workplaces.

The Allen Bradley 1734-EP24DC includes two green indicator lights-one for field power status and another for 5V system power-that enable simple visual checks. It provides input dropout prevention, ensuring that output parameters are maintained for 10ms at full load even when the input voltage dips to 10V. With a continuous isolation voltage of 50V and a 24V DC field power bus, the module provides safe and efficient power distribution to attached I/O modules. It also comes with various certifications, including CE, UL, CUL, and GOST, indicating that it meets global industrial safety and performance standards.

Application scenarios

Another key application for the Allen Bradley 1734-EP24DC is in process control systems found in chemical plants, water treatment facilities, and oil refineries. These industries require precise power distribution to I/O modules that monitor and control pressure, flow, and temperature. The module's reverse polarity protection protects against wiring errors, while its input dropout protection keeps power steady for 10ms even if the input voltage dips to 10V-essential for preventing costly shutdowns in sensitive process activities. As a dependable Allen Bradley 1734-EP24DC POINT I/O power module, it carries global certifications, including CE and UL, providing plant managers confidence in its safety and performance.

The Allen Bradley 1734-EP24DC is also well-suited to machine tool automation. Metalworking businesses' CNC machines, milling tools, and lathes rely on distributed I/O systems to handle motion control, tool positioning, and safety interlocks. The module's tiny size (76.2×25.4×133.4mm) allows for easy installation on DIN rails in control cabinets, saving space while providing the necessary 1A to 1.3A output current to power attached I/O modules. Its lightweight (120g) and sturdy design make installation and maintenance straightforward, especially in the confined cabinet spaces found in machine shops.

FAQ

Q: What is the Allen Bradley 1734-EP24DC?

A: The 1734-EP24DC is a 24V DC expansion power supply module from Rockwell Automation's Allen-Bradley brand, designed specifically for the POINT I/O system. It is not a programmable controller but a power module that provides additional, localized power to I/O modules within a POINT I/O assembly, enhancing system reliability and flexibility.

Q: When should I use a 1734-EP24DC power supply module in my system?

A: You should integrate this module when your POINT I/O assembly requires more power than the main system power supply can deliver. This is common in larger or more complex racks with many digital or analog modules. Using a 1734-EP24DC helps prevent voltage drops, ensures stable operation of all I/O points, and is a best practice for creating robust distributed control systems.

Q: Can the 1734-EP24DC be used with other Allen-Bradley controllers like CompactLogix?

A: Yes, absolutely. The POINT I/O system, including the 1734-EP24DC, is designed to seamlessly integrate with Allen-Bradley's broader Integrated Architecture. It is commonly used as a remote I/O station with CompactLogix and ControlLogix programmable automation controllers (PACs) over networks like EtherNet/IP, often via a 1734-AENT communication adapter.
