Honeywell 51120841-101 DCS Module (Unik Series)

Honeywell 51120841-101 Module (Unik Series)

Technical Details:

• Model Numbers: EC7830A or EC7850A

• Site-Configurable Jumper Options:

• Three jumper options for configuration settings

• Jumpers are read at startup and locked into internal memory after 200 hours of Main Valve operation

• Altering the jumpers after lock-in will cause the module to lock out, ensuring no modifications can be made post-installation

Operational Sequence:

• INITIATE Sequence:

• The module enters the INITIATE sequence when the Relay Module is powered or if it detects voltage or frequency fluctuations.

• Voltage fluctuation tolerance: +10/-15%

• Frequency fluctuation tolerance: +/-10%

• The INITIATE sequence lasts for two seconds if tolerances are met. Otherwise, a hold condition is initiated if tolerances are not met.

Features:

• Safety Feature: The module locks configuration jumper settings into its internal memory after a specified operational period to prevent post-installation modifications.

• Voltage and Frequency Monitoring: Ensures stability by entering the INITIATE sequence or hold condition when voltage or frequency fluctuations are detected, protecting the system from potential damage or incorrect operation.
