Product Overview

The Honeywell 900H01-0202 provides high-capacity switching functionality for the HC900 Process Automation System. This 8-channel digital output module utilizes electromechanical relays to control field devices such as motor starters, solenoid valves, and interposing relays. By incorporating a mix of Form A and Form C contacts, the module offers versatile wiring configurations for both normally open and changeover circuit requirements. We supply this module as 100% Brand New in original packaging to ensure maximum contact life and switching reliability in your critical control loops.

Technical Specifications

Engineering Advantages

• Flexible Load Handling: The module manages up to 4 Amps per relay, allowing direct control of mid-sized industrial actuators without the immediate need for external interposing relays. This reduces cabinet footprint and total system cost.

• Advanced Galvanic Isolation: Superior isolation between individual relay contacts and between field-side and logic-side circuitry prevents ground loops and protects the HC900 backplane from external electrical surges.

• Dual Contact Variety: By providing both Form A and Form C contacts on a single card, engineers can implement fail-safe configurations (normally closed) and standard switching (normally open) simultaneously using one module slot.

• High-Speed Execution: Max response times of 11ms (ON) and 8ms (OFF) ensure that your process automation system reacts rapidly to logic changes, maintaining tight control over time-sensitive industrial processes.

FAQs

• What is the difference between Form A and Form C contacts on this module?

  The 900H01-0202 contains 4 Form A contacts, which function as standard "Single Pole Single Throw" (Normally Open) switches. The remaining 4 channels are Form C, which are "Single Pole Double Throw" (Changeover) switches providing both a Normally Open and a Normally Closed terminal.

• Does this module support incandescent lamp loads?

  Yes, however, the current rating de-rates to 0.5 A at 240VAC or 30VDC for incandescent lamp loads due to high inrush currents.

• Can I replace a faulty module while the system is running?

  The HC900 architecture supports module replacement; however, you must ensure that the field-side voltage (up to 240VAC) is safely isolated before removing the module to prevent electrical shock or damage to the rack.

• Is this a genuine Honeywell part?

  We guarantee the 900H01-0202 is 100% Brand New and Original from Honeywell. Every unit ships in its original factory box and includes a comprehensive 12-month warranty.
