About 1769-PB4
Allen Bradley 1769-PB4 is a compact I/O power supply. This module is part of the 1769 Compact I/O product series and operates at an external power supply voltage of 19.2-31.2 VDC and a nominal power supply voltage of 24 VDC. This power module provides the appropriate current consumed by the modules installed on its left and right sides. A maximum of eight (8) modules can be installed on both sides of the power supply.
The current capacity of 1769-PB4 is 4.0A at 5VDC and 2.0A at 24VDC. It can withstand a maximum surge current of 30 A, with an isolation voltage rating of 75V (continuous), and a reinforced insulation type (requiring IEC Class 1 grounding). The routine test lasts for 1 second at 1697V DC, with DC power input to the system.
The power consumption of 1769-PB4 is 100 VA @ 24V DC and 14.5 W @ 60 ° C (140 ° F). This power supply is equipped with an internal fuse, which can be Wickmann 19193-6.3A or Litteluse 021706.3MXP.
The physical dimensions of 1769-PB4 are 118 (H) x 70 (W) x 87 (D) millimeters (4.65 x 2.76 x 3.43 inches), and it weighs approximately 630 grams (1.39 pounds). This power module follows the recommended installation of the CompactLogix product series, as it is installed directly onto the enclosure sub panel or uses standard DIN rails. When terminating the signal and input wires of this power supply, the recommended wire diameter is 14 AWG (2.5 mm2) solid copper wire with an insulation rating of 90 ° C (194 ° F) or higher, and the maximum insulation thickness is 1.2 mm (3/64 in.).
