ALLEN BRADLEY 1771-P4S is a 4-slot, chair-mount power supply module manufactured by ALLEN BRADLEY. It is a 19-inch, SCSI-style power supply that provides 90-270 VAC, 42/24 VDC, 50/60 Hz, and 20A of power to up to 4 slots of SCSI-style I/O cards. The module contains an internal power supply, an e-stop switch, an AC circuit breaker, and an output indicator that has 3 LEDs for each power supply. Included in the module is a 4-pole Removable Terminal Block (RTB) which allows for the connection of the power supply to the I/O cards. The power supply is compressor-based and designed for use in extreme environmental conditions. It is UL approved for use in hazardous locations and is designed to meet any other necessary safety requirements and certifications. The module contains a voltage adjustment capability that allows the user to adjust the terminal voltage on the module to match the load requirements of the system. This adjustment capability includes a voltage selector switch, a voltage display switch, and manually-controlled voltage trimming. It also has a failsafe mode in case of an unexpected system failure. The failsafe mode is designed to protect against high-voltage faults, short-circuited connections, or surge current. It is capable of detecting these problems and shutting off the power supply with no warning or user intervention. The power supply is designed to meet the exacting requirements of quality and reliability for which ALLEN BRADLEY is known. It is PCB compatible and designed for use in a wide range of industrial-grade applications. Its low-profile chassis and RFI compatibility make this module an ideal solution for a variety of control applications. In addition, 1771-P4S is an easy-to-use and efficient power supply that is designed to provide reliable performance. Its plug-and-play design enables fast and easy installation with no additional programming required. It also contains a protection feature that guards against short circuits and power surges. The module also includes an overload protection feature that automatically shuts down the power supply in the event of an overcurrent or overvoltage. All of these features make this power supply an ideal solution for industrial-grade applications where reliable performance and cost efficiency are a priority.
