DA2RS is a universal converter with analog output used for control and regulation. Two independent analog outputs can be either voltage or current. Available ranges are: 0 - 10 V, 0 - 5 V, ±10 V, ±5 V, 4 - 20 mA, 0 - 20 mA, 0 - 24 mA. Values for the outputs are sent from a control system using RS232 or RS485 line.

DA2 analog outputs can be used for process regulation and automation or controlling analog inputs (e.g.  electronic thermostats, electronic valves, speed control, dimming of lighting,...).

Princip funkce

Device function principal

Features

  • Two analog outputs (independent settings for current or voltage). Available ranges:
    0 – 10 V, 0 – 5 V, ±10 V, ±5 V, 4 – 20 mA, 0 – 20 mA, 0 – 24 mA
  • Output range divided to 10 000 divisions.
  • Active current outputs.
  • Each output galvanically isolated.
  • 16 bit D/A converter
  • RS232 or RS485 communication using Spinel or Modbus RTU.
  • Wide power voltage range (8 to 30 V).

Block diagram

The device is divided into four completely galvanically isolated sections:

  1. Power and processor unit,
  2. communication lines (RS232 a RS485),
  3. output 1,
  4. output 2.

Dueto the galvanic isolation, the analog converter can be connected to other systems without damaging the equipment or adversely affecting the systems beacuse of the connection of different voltage potentials via a common ground conductor..
