The 1769-PA2 is a 1769 CompactLogix Power supply, manufactured by PLC. This power supply has a current capacity of 0.8A at 24 VDC.When installing the PLC 1769-PA2, an adjacent space of 50 millimeters must be left between it and nearby equipment in order to ventilate it properly. Also, when mounting the power supply module, make sure that no static, UV radiation, or debris will touch the module during installation or operation. Excessive heat must be avoided since this could cause damage to the whole power supply module. When the ambient temperature is excessively high, several ventilation methods must be applied. The 1769-PA2 module is an open power supply that has no enclosure.
The PLC 1769-PA2 power supply can also be mounted on a DIN rail. An important thing to note when installing this power supply module is that it needs to be grounded. When connecting the module, a 14 AWG wire must be used and the leads must be kept as short as possible. The recommended wire type is a copper wire with a resistance of at least 90 degrees Celsius. It is recommended to place the PLC 1769-PA2 compact I/O expansion power supply in an enclosure that protects the module from a corrosive atmosphere or contaminants that might come from the open air. If it is used in an enclosure, the use of air conditioners is recommended to combat the heat around the enclosure. The PLC 1769-PA2 compact I/O expansion power supply comes with a fuse that offers protection against abnormal line transients and short-circuit currents. The 1769-PA2 module runs on 120 to 240 Volts of AC input power at a frequency between 47 and 63 Hertz. This power supply weighs only 2 pounds and it only measures 8 x 8 x 5 inches, making it easy to ship.
