User’s Manual 3
This document describes the technical and functional characteristics and how to use the DIPOT board.
The available models are identified by the following codes:
1.
E6102094300xx
: DIPOT RS485 IN 0÷5V/IN 0÷10V
2.
E6102094301xx
: DIPOT RS485 IN TEMP./PRESS. VDO
3.
E6102094302xx
: DIPOT CANBUS IN 0÷5V/IN 0÷10V
4.
E6102094303xx
: DIPOT CANBUS IN TEMP./PRESS. VDO
Thanks to its versatility, the "DIPOT" device lets you connect most products (Speed regulators, Voltage
regulators, Power factor controllers, etc.) that require a voltage or current input, to suit their variation and
management specifications. The output for piloting the boards is managed by a microcontroller that
controls the regulation of an output proportional current loop (which can be converted into a voltage
output using a simple resistance).
The output can be regulated and piloted with UP and DOWN digital inputs, or by modifying the Modbus
protocol registry value via RS485 connection or CANBUS J1939 connection to our generator
management boards DST4601, DST4601PX, DST4400, etc.
2.1
On all DIPOT models, the regulation of the Current Loop can be selected using three configurations of
dip-switches:
from 0 to +20 mA
from -10mA to +10mA
from -20mA to +20 mA
Using one of the current adjustable outputs we can create a voltage output by connecting a resistor to
pins 2 and 3 of connector J1.
The current loop device output is between pins
+4
,
+3
for the positive, and pins
-2
,
-1
of
J1
for the
negative. The resistor can be connected to pin
2
and pin
3
of
J1
.
Warning: Carefully consider the resistor and the dip-switch configuration, as the max.
voltage range is ± 11V.
Here are some examples:
Example 1:
Voltage required: min. -6V to max. +6 V.
Select ± 20mA
