COMMUNICATION - RADIO

  • 900MHZ, 1 WATT power at 19,200 baud spread spectrum
  • Over 40 mile transmission with directional antenna
  • RS485 communication port
  • 1 microamp sleep mode
  • LEASE LINE MODEM
  • 19,200 Baud, two wire lease line

The Myriad RTU1 ushers in a new generation of RTU’s. With its 20 I/O capability, graphical backlit LCD display, full user programmability, rugged Nema 4X housing, the Myriad RTU1 offers unmatched versatility in small SCADA applications.

The unit accepts a control analog input and allows the user to control two local outputs R1 and R2. Relay 3 and 4 outputs are energised based upon programmed setpoints in the slave RTU. 3 analog inputs are ‘mirrored’ as 3 analog outputs on the remote RTU. 4 digital inputs DI/1 – DI/4 are repeated on the 4 solid state outputs of the remote RTU. Dual RS485 ports provide true peer to peer networking.
