608 SBC Controller Board

608C controller board608C Controller Board

The 608C SBC is an outgrowth of the 6008SX/ES series of intelligent RTUs which have been used for applications such as Pump Off Control and Water and/or Gas Injection control.

The 608C SBC is designed with a 16 bit processor, a real-time clock, and a mix of Input/Output channels that directly meet many application requirements. The I/O complement can be expanded through a smart port or RS-485 networked I/O cards. The 608C executes applications written in the C programming language. It fills the gap where a low cost, low power, intelligent remote controller is needed.

The 608C SBC is a completely self contained controller that communicates at 1,200 to 460,800 (115,200 with standard configuration) bps using AutoCom, Modbus, or custom protocols. It has sufficient power to handle applications such as pump-off control or AGA gas flow calculations. Low cost and high performance have been the design criteria. It is available with a 12 VDC Solar Power Package, or a 110 VAC power package.
