The 1774-P1 power module is a PLC1 base power supply. Manufactured by Allen-Bradley, the base power supply is categorized under the PLC series of Allen-Bradley modules. It weighs approximately 16.12 kilogramsĀ with dimensionsĀ of 480 millimetersĀ xĀ 440 millimetersĀ x 200 millimeters. The PLC1 pase power supply module features a serial port used for communication between the module and connected applications. The 1774-P1 module interfaces different applications to the Allen-Bradley programmable controllers within the 1774 universal I/O structure. The unit is built to support high-power operations. The built-in AC solid-state family of digital I/O modules meets the user requirements for different applications. The 1774-P1 power module also comes with system protection and troubleshooting aids. The AC-powered I/O modules haveĀ electrical-optical isolation with filter circuits. ThisĀ feature is important forĀ module troubleshooting.
The front panel on the 1774-P1 power module features status indicators thatĀ makeĀ monitoring and troubleshooting the module easier because theyĀ makeĀ itĀ easyĀ for the users to recognize the faults.Ā The 1774-P1 module should be stored and installed under properĀ conditions to protect itĀ from radiated noise or heat. The module also features input filtering capabilities. This limits the effects of the voltage transients that are usually caused by contact bounce andĀ electrical noise. If filtering is not done appropriately, the 1774-P1 module's voltage transients will produce false data. The 1774-P1 module contains the output circuitry that is used for controlling whether the module is on or off. ItĀ comes with surge suppression circuitry for the output. Moreover, the unit comes with the metal oxide varistor between each set of terminals. This ensures the suppression of the high-voltage transients.
