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,...).
Device function principal
The device is divided into four completely galvanically isolated sections:

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..
