The AB 1756-OF8 is an analog output module that is part of the ControlLogix platform. This analog module may be used to control and modulate electrical and field devices, transmit or re-transmits signals for interfacing with measuring and recording instruments or for any other purpose.

The 1756-PB75 is a Standard ControlLogix power supply. This power supply is a DC powered module, mainly used to deliver backplane power and enable module operation. This power supply is mounted on the left most side of a particular ControlLogix chassis.

The 1756-PB75 is compatible with most of ControlLogix chassis, particularly Series B and Series C 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17 chassis. When terminating incoming power connection to this power supply, recommended wire size is 2.5 mm2 or 14 American Wire Gauge (AWG) solid or stranded copper wire with insulation rating of 90 °C (194 °F), or higher and maximum insulation thickness of 1.2 mm (3/64 in.). Tighten screw with Torque of 0.565 N-m (5 lb-in).This power supply has physical dimension of 14.0 (H) x 11.2 (W) x 14.5 cm (D) (5.51 x 4.41 x 5.71 in and weighs 0.95 kg (2.10 lb).

The 1756-PB75 is externally powered by a nominal supply voltage of 24VDC with applicable voltage range of 18-32VDC. It has an input power rating of 95W and inrush current rating of 30A. It delivers an output power of 75 W @ 0…+60 °C (+32…+140 °F) and current capacities of 1.5 A at 1.2VDC; 4A at 3.3VDC; 13 A at 5.1VDC and 2.8 A at 24VDC. This power supply also features hold up time of 35 ms @ 18V DC; 40 ms @ 24V DC and 40 ms @ 32V DC with isolation voltage of 250V (continuous), Reinforced Insulation Type, Power Input to Backplane Type tested @ 3500V DC for 60 s.

It is part of the 1756 ControlLogix product family that also provides power to the chassis backplane. The 1756-PB75 has an input voltage range between 18 and 32V DC with 24V DC nominal and a power rating of 95W input power and 75W maximum output power at 0-60 °C. The module has a maximum surge current of 30A and a signal hold up time of 35ms at 18V DC, 40ms at 24V DC, and 40ms at 32V DC. It has a current capacity of 1.5A at 1.2V, 4A at 3.3V, 13A at 5.1V, and 2.8A at 24V DC. The 1756-PB75 has an isolation voltage of 250V using a reinforced insulation type tested at 3500V DC for 60s between power input-to-backplane.
