About this file

Written by GovTribe AI ·

The document is a set of electrical schematic drawings for ElectroMechanical Relays Main Control Boards for Units 1 and 2, created by Washington Electric Controls, Inc. The drawings detail complex relay configurations, including master start auxiliary relays, unit run relays, loss of field relays, generator brake air cylinder pressure switches, and various timing and shutdown relays for multiple electrical system components. The schematics are technical diagrams showing interconnected relay systems, with detailed labeling for each relay's function and electrical connections across different panel views and unit configurations.

The drawings are specifically associated with a federal solicitation (FY255701042) by the International Boundary and Water Commission for Electro-Mechanical Protective Relays at the Amistad Field Office in Del Rio, TX. The solicitation is a 100% small business set-aside with a Product Service Code of K059 for modification of electrical and electronic equipment components. Quotes are due by June 24, 2025, at 3:00 pm MST, with an evaluation approach focused on technical acceptability and lowest price technically acceptable (LPTA) criteria. The procurement seeks to upgrade existing relay systems, with the attached drawings likely serving as reference documentation for potential offerors to understand the current electrical control board configuration.
