Station with 8 current relays, display and RS-485 communications

CDR-8

CDR-8

Code: P32111.CONSULTAR DISPONIBILIDAD

  • 8 current relays station, display, RS-485 communications. Measurement range 0,03 to 63 A

INFORMATION

Description

The CDR-8 unit measures, calculates and displays the current of 8 independent channels. Each channel can be configured as an earth leakage or current relay. It measures the true root mean square, taking decisions about the operations being carried out. It can work as a maximum or minimum current relay or as an earth leakage relay. The CDR-8 can show the earth leakage current and status of the operations relay of each of the 8 channels on an LCD display.

The device comprises :

  • 8 input channels: Measurement using WG and/or WGP series transformer.
  • 8 operation relay outputs (1 per channel)
  • 1 alarm relay
  • Operation logging recording
  • RS-485 PC communication
  • Auto-reset programming option (on RS-485 differential channels)
  • RS-485 PC communication The "PowerStudio" PC software enables you to display, record, create graphs and logs, etc.

Applications

This unit can be used to measure and control the current of up to 8 lines, with a set of reduced dimensions.
