About this file
This specifications document outlines requirements for an environmental control plots control system hardware project for the USDA Agricultural Research Service. The system must include eight control panels and specified field devices to monitor and control twelve peanut plots. It requires a master control panel in the main building, an outdoor HMI panel on an outside wall, and six distributed plot control panels near their assigned plots. The panels and field devices must meet new electrical safety codes and replace obsolete equipment. Key components include Opto22 control systems, rainfall and temperature sensors, contactors, motors, gearboxes, and proximity sensors. Schematics of the electrical system will be provided by the winning bidder upon completion.

Specifications for Environmental Control Plots Control System Hardware
The USDA, ARS, NPRL in Dawson, GA requires a monitoring and control system for 12 peanut plots. This system needs to include a total of eight control panels and specified field devices intended for installation and software development at a later time. New panel are to bring equipment up to new electrical code and to insure the correct data collection and controls for research.
Our Rainfall Control Plot Facility needs new control panel, to meet new electrical safety codes and to replace obsolete equipment. This is purchase is for the Opto22 control panels and 12 2HP TENV motors paired with 12 right angle gearboxes.
The system will consist of a. (1) Master Control Panel to be in the air-conditioned main building, b. (1) Outdoor HMI Panel to be located on an outside wall of the main building, c. (6) Distributed Plot Control panels to each be in proximity their assigned plots, and d. specified field devices as defined below.
a) The Master Control Panel includes the following: Opto EPIC or Groov RIO with I/O for 2 Rainfall Sensors and local VFD Interaction, 12 Control Techniques 2HP VFDs, HMI Touch Screen, Power Supply, and
Ethernet Communications.
b) The Outdoor HMI Panel includes the following: HMI Touch Screen, Power Supply, and Ethernet
Communications.
c) The 6 Distributed Plot Control Panels each include the following: Opto EPIC or Groov RIO with I/O for 12 4-20ma Humidistat inputs, 12 Type T Thermocouple inputs, 28 DC inputs for contactor auxiliary signals, 4DC inputs for rooftop proximity sensors, and 2 Relay Outputs to control the 28 mini contactors for heat strip control. For Heat Strip Control there are two independent groups of 14 mini-contactors.
Also included is a Power Supply as well as Ethernet Communications.
d) Field devices include the following: 24 Balluff proximity sensors for roof end of travel detection with up to 15M cord sets. For roof control there are 12 2HP TENV vector duty motors paired with 12 right angle gearboxes.
e) Schematic drawings of the system’s electrical system/components will be supplied by winning bidder upon the completion of the build.
