Allen-Bradley 1769-PA2 DC Power Supply Module

The Allen-Bradley 1769-PA2 Compact I/O expansion power supply converts an 85–265 V AC input to dual DC rails that feed 1769 Compact I/O modules: 5 V DC up to 2 A and 24 V DC up to 0.8 A. It delivers about 100 VA at 120 V AC (130 VA at 240 V AC) with isolation between the AC power input, the 24 V DC user power rail, and the I/O bus rated at 265 V continuous. The unit supports up to eight I/O modules on each side, enabling flexible rack configurations within a CompactLogix 1769 system. The PA2K variant adds conformal coating for harsher environments, and fuse options include Wickmann 19195-3.15A or Littelfuse 02183.15MXP as applicable to production variants.
