DR-1 - Remote Digital Display

Remote digital displays with 4 1/2 digits for flow rate and 8 digits for totalization. Includes scaled, open collector output for remote totalizer. Numeric password protection prevents unauthorized access to menu. The easy to read menu prompts make the DR-1 so easy to program. An isolated scaled pulse output is available for hook up to a remote totalizer.

This remote digital display can be used with our 4-wire transmitter linear signal (Option W) as well as our 2-wire transmitter square root signal (Option W2, and W3) both provide 4-20mA signal Output which is proportional to flow rate, the digital display requires a 24Vdc power supply which can be purchased separately (PS-24 Power Supply) . The W2 and W3 requires a square root extraction at the receiving end.

PS-24 Power Supply

This module converts unregulated AC to regulated DC output. A compact supply to power various DC operated peripherals and input / output modules on PLC's or transmitter options W, X, Y, Z or W2, W3 and RW3.  The PS-24 module converts 115VAC to DC. The PS-24 can deliver 100mA of regulated 24VDC for transmitters running on 24VDC.  Input Power: 115 or 230VAC 50/60 Hz (external fuse recommended).

  • Screw Terminal Connection
  • 100mA of Regulated Power at 24Vdc
  • 115 Volts 50/60 Hz Input
  • Easily Mounted
