PLCs, Power Supplies & Others

The Honeywell 900PSM-0101 functions as a dedicated power supply monitor module for Honeywell ControlEdge HC900 systems. This unit continuously monitors the status of redundant power supplies, ensuring both units function correctly. Consequently, it provides clear visual status indications to operators for maintaining system availability.

Core Technical Specifications

We engineered the Honeywell 900PSM-0101 for reliable monitoring of redundant power architectures in critical control applications. The table below details its essential electronic and physical parameters:

Redundant Power Supply Monitoring

The 900PSM-0101 continuously checks the operational status of both primary and redundant power supplies in the system. It verifies that each supply is delivering correct voltages and functioning within specifications. Therefore, operators gain confidence that power redundancy is fully available when needed.

Clear LED Status Indication

Green directional LEDs on the module front panel provide immediate visual feedback on power supply health. These indicators show which supplies are operational and if any have failed or are degraded. Consequently, maintenance personnel can identify issues at a glance without additional tools.

Minimal System Power Loading

This monitor module draws only 22 mA maximum from the 5V system supply, imposing negligible load on power resources. Its low power consumption ensures it does not impact the overall power budget of the ControlEdge HC900 system. As a result, you can add monitoring capability without affecting existing power margins.

Hot-Swap Support for Continuous Operation

You can insert or remove the 900PSM-0101 while the ControlEdge HC900 system remains fully powered and operational. This hot-swap capability allows for module replacement or maintenance without system shutdown. Hence, it supports the high availability requirements of critical industrial processes.

Seamless ControlEdge HC900 Integration

The module plugs directly into the HC900 rack, integrating seamlessly with other system components. It communicates status information via the backplane for possible integration with control logic or alarms. Therefore, engineers can incorporate power supply status into their overall system monitoring strategy.

Essential for High-Availability Systems

In systems requiring maximum uptime, redundant power supplies are essential but only useful if both function correctly. The Honeywell 900PSM-0101 provides the assurance that redundancy is truly available when needed. Consequently, it plays a vital role in maintaining continuous operation in critical applications.

Compact Design for Space Efficiency

The module occupies minimal space within the ControlEdge HC900 rack, preserving slots for other I/O functions. Its compact footprint aligns with the modular design philosophy of the HC900 platform. As a result, you can add power monitoring without sacrificing valuable I/O capacity.
