Honeywell 620-0036 AC Power Supply with Battery Backup

Product Overview

The Honeywell 620-0036 serves as the primary energy source for the IPC 620 Programmable Controller system. This module converts AC line voltage into the regulated DC power required to drive processors, communication cards, and I/O modules across the backplane. Beyond power conversion, it functions as a critical data protection device, housing a dedicated battery compartment to maintain volatile memory during total power loss. Despite its legacy status, this module remains essential for maintaining the operational integrity of existing IPC 620 infrastructure.

Condition: 100% Brand New, Original Industrial Stock.

Technical Specifications

Engineering Advantages

• Global Voltage Versatility: The 620-0036 features a selectable input toggle for 115 VAC or 230 VAC. This flexibility allows engineers to deploy the same module across different regional power standards without requiring external transformers.

• Integrated Memory Safeguard: The built-in lithium battery compartment ensures the controller retains its logic program and register data during utility failure. This prevents the need for time-consuming program reloads and minimizes system recovery time after an outage.

• Advanced Power Conditioning: Internal surge suppression circuits filter out high-voltage transients often found in factory environments. This protects the sensitive semiconductor components of downstream I/O and CPU modules from premature failure.

• Automatic Overload Recovery: The power supply incorporates intelligent overload protection. In the event of a backplane short-circuit or excessive current draw, the module throttles output to prevent hardware damage, resuming normal operation once the fault clears.

• Industrial Thermal Range: With an operating window of –20°C to +60°C, the module withstands the temperature fluctuations common in unconditioned control cabinets, ensuring consistent DC regulation in both winter and summer conditions.

FAQs

How do I switch between 115V and 230V input?

The module contains a physical jumper or switch (refer to the side-panel label). You must set this to the correct voltage before applying power. Applying 230V while the unit is set to 115V will cause immediate internal damage to the surge suppression stage.

When should I replace the backup battery in the 620-0036?

We recommend replacing the lithium battery every 2–3 years regardless of power outage frequency. Since this unit is brand new, ensure you install a fresh battery upon commissioning to guarantee maximum memory retention time.

Does the 620-0036 power the field-side sensors and actuators?

No. This module provides power strictly for the internal rack components and logic circuitry. You must provide a separate external power supply for your field-side I/O devices (sensors, solenoids, etc.) to maintain electrical isolation between the logic and field circuits.

Is this module hot-swappable?

No. Because the 620-0036 provides the primary power for the CPU, removing it while the system is active will cause an immediate controller shutdown. Always power down the rack before removing or installing the power supply module.
