Connectivity

The Brain® – Digital Re-Circulating Valve (DRV) and all derivative assemblies are provided as standard with the following communication capabilities:

SPCO Relay Outputs – Relay which is energized during operation and switches from a normally open position upon the presentation of an error code. Can also be configured to activate upon a temperature alert condition. Relay may be used to connect to a remote alarm or solenoid valve.

LCD Display – Provides information on set point, delivered temperature with an option for C or F and displays all error codes and alert conditions.

RS485 Serial Port – Connects the DRV to either BrainScan® or Modbus.

BrainScan® an optionally selected control module which enables an interface with Building Automation Systems (BAS) which utilize Modbus, Bacnet™ or LonWorks™ protocols. BrainScan also has an ethernet port and operates as a web server for remote network access.

Modbus – DRV can be configured to communicate directly with Building Automation Systems which use Modbus protocols. When configured for Modbus the DRV becomes a Remote Terminal Unit (RTU).

* Note: Flow capacities indicated at 7.5 ft/sec pipeline velocity.
