PLCs, Power Supplies & Others

This power supply module provides DC power for Honeywell 620 series control systems. It converts AC line voltage to regulated outputs for backplane modules. Therefore, this component ensures stable operation of industrial automation controllers.

Physical Dimensions and Weight Specifications

The Honeywell 620-0047 features a rugged metal housing for industrial use. Its width occupies a single slot in the 620 series rack. The module depth measures 220 mm for backplane connectivity. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The Honeywell 620-0047 provides a 3-terminal AC input block on the front panel. A 4-terminal DC output block connects directly to the backplane bus. The front panel carries an LED indicator for output status. Hence, operators can verify power availability at a quick glance.

Component Count and Internal Architecture

This power supply contains one main board with a switching regulator circuit. The board holds four large electrolytic capacitors for output filtering. You will also find a bridge rectifier and a high-frequency transformer. An onboard fuse protects the unit from overcurrent events.

Energy Storage and Hold-Up Time

The Honeywell 620-0047 stores energy in four 1000µF output capacitors. This storage provides a 20 ms hold-up time after AC loss. Therefore, the backplane modules continue operating during brief power dips. The unit requires no external battery for this function.

Protection Features and Operating Range

The power supply includes short-circuit and overvoltage protection. It also features thermal shutdown with automatic recovery. Users can operate this unit in temperatures from 0°C to 50°C. Natural convection cooling eliminates the need for a fan.
