General description
The din20 din rail isolators are based on Arian id20 digital panel indicators, having the
same funtionalities except for not having a display and enhaced isolation characteristics. Composed by 3 sub-models (din20-bas, din20-vac, din20-tac) they cover a broad
range of input types.
Isolation
Complete galvanical isolation between: power supply, input, analog output, solid state
relays and RS485 communications.
Inputs
The din20-bas includes thermocouples, Pt100, 4...20mA, 0...10V and 0...50mV
process inputs.
The din20-vac is a AC true RMS volt and amper input instrument, (also bipolar DC)
with several scales. May be used with shunts, current transformers or direct measurement of AC/DC voltages up to 600V.
The din20-tac is a tachometer or rate meter, only accepts pulse inputs e.g.. NPN, PNP
and Mechanical Switch. Frecuency measurement is done counting the input pulses
and simultaneously measuring the time among them. This method allows precise and
quick readings especially at low frequencies where the measurement is obtained
mainly from the period (time) among pulses. Simplifies input programming not having
to define "time windows" on which the count is carried out.
Alarms
Possess two output solid state relays, each one corresponds to 2 programmable
alarms (high and low). Alarms can be absolute or relative to a general set point.
Analog output
Isolated analog outputs 0/10Volt, 4/20mA active or loop powered.
Programming
Set up and configuration is done by the Arian RPS software running on a PC. Computer connection is made to the RS485 port (using the ISO485 interface) or to the
internal connector with the RPS interface.
Since funtionalities are exactly equivalent with the id20 panel meters, detailed configuration is found on the id20 user manual.

PROGRAMMING
Set up configuration is done with the RPS (remote programming ) software provided on
http://www.arian.cl/downloads/arianrps.zip and running on windows PC.
Connection can be done from the RS485 lines using the ISO485 interface to the PC RS232 comm port .
Also may be done using the RPS interface cable plugged to the internal connector, taking care of the “UP”
direction for the connector, as seen on the figure.
Remove the four top cover screws for accessing the RPS connector and other internal jumpers needed for
setting the input and output type.
UP
RPS Connector
The RPS software will recognize the device and load the proper driver for reading and writing configuration
parameters.
Since the din20 is functionally equivalent to the ind20 panel meters, you may refer to the id20 user manual
for further references.
