Model 6790 Stand-Alone RTU

The Totalflow Model 6790 RTU is designed to address requirements for remote, low power RTU applications for SCADA

The Totalflow Model 6790 RTU is designed to address requirements for remote, low power RTU applications for SCADA. The 6790 includes a self-contained battery power source and solar charging system, and is packaged in a rugged, field-proven, NEMA 4X weather-tight enclosure. The 6790 RTU can be networked via RS485 with other RTU’s and/or Totalflow devices.

Constructed around a proven industrial control language, the Totalflow Graphically Enhanced Ladder Logic (GELLO) allows users to meet a wide variety of application requirements. Logic designs are composed in a Windows object oriented environment using a desktop computer. Once designed, logic can be simulated and debugged before installation into the RTU. Logic designs are constructed from graphic building blocks that include.

  • ISA Symbol Coils
  • Timers
  • Contacts
  • Analog I/O
  • PID Controllers
  • “User-defined” Blocks
  • C Program Calls

The standard complement of Model 6790 I/O affords users the maximum utility with minimum power usage. Each 6790 RTU has the following I/O:

  • Eight Digital Inputs: Senses dry contact input (zero ohms); read once per second; not operational with non-dry contact (active) inputs.
  • Eight Digital Outputs: DC voltage supplied when active or set; DC voltage available determined from power source and total combined current available:
    • – Internal Power: Battery voltage @ 2 amps
      – External Power: External voltage @ 4 amps
  • Seven Analog Inputs: 0-5.25 VDC (0-21mA with resistor):
    • – 13 bit resolution
      – Non-differential inputs
  • One to Four Analog Outputs: 4-20mA output; 12 bit resolution; 250 ohm minimum load.
  • Two pulse inputs: (Rate or Accumulating)
    • – Active Input: 20KHz input; 0-5 V minimum pulse input; 0-12 V maximum pulse input.
      – Contact Closure Input: 0-100Hz frequency input.
