Product features

The Allen-Bradley 1769-PB4, a key component of Rockwell Automation's CompactLogix series, has a dual independent power supply design that can provide reliable power to I/O modules (5V DC, up to 4A) and peripheral devices (24V DC, up to 2A). Its dynamic load response performance is particularly impressive, with a surge current of up to 30A (at 31.2V DC) can readily manage immediate peak demands such as motor starters and solenoid valve actions.

The 1769-PB4, at 118mm × 70mm × 87mm, sets new norms for compact design. Its lightweight design (just 630g) allows for dual-mode installation on DIN rails or panels, making it suitable for deployment in dispersed control systems or control cabinets with limited space.

As part of the CompactLogix ecosystem, the 1769-PB4 works seamlessly with 5380/5480 controllers and 1769 series I/O modules, allowing for high-speed communication via the EtherNet/IP protocol. The module is fitted with LED status indicators that indicate input/output voltage states in real time, allowing engineers to easily locate defects.

The 1769-PB4 has a built-in 6.3A replacement fuse (compatible with the Wickmann 19193 model), over-voltage protection, and auto-reset short-circuit capabilities that can terminate fault circuits in 10 ms. Its aluminum alloy housing and sophisticated temperature management design not only allow for efficient heat dissipation, but they also meet IP20 dust protection standards, effectively preventing dust and EMI interference.

FAQ

Q: Can the Allen-Bradley 1769-PB4 handle voltage fluctuations in the on-site power supply (e.g., ±15% voltage deviation)?

A: The 1769-PB4 module has an input voltage range of 24V DC ±15%, allowing for voltage swings of 20.4V to 27.6V. This design can handle common power supply changes in industrial environments, such as a ±15% deviation, assuring stable operation of the equipment.

Q: Is the 30A surge current of the Allen-Bradley 1769-PB4 momentary or repeatable?

A: The power supply module's surge current is a transient current spike designed to fulfill the high energy demands of equipment when it first starts up. The 30A surge current on the 1769-PB4 module is most likely transient, lasting only a few milliseconds.

Q: Does DIN rail mounting require additional accessories?

A: The 1769-PB4 module normally does not require any additional equipment for DIN rail mounting; it can be firmly fastened with the built-in latch.
