MicroElektronika click BOARD 4-20mA T Manual

4-20mA T click

1. Introduction

4-20mA T Click™ is an accessory board in
mikroBUS™
form factor. It's a compact and
easy solution for adding 4-to-20mA industry
standard communication protocol to your
design. It features ADuM1411 Quad-chanel
MCP4921
digital isolator, 12-bit DAC as well
as XTR116 4-20mA current loop transmitter.
4-20mA T Click™ communicates with target
mikroBUS™
board microcontroller via three
SPI lines (SDI, SCK, CS). The board is designed
to use 3.3V and 5V power supply. LED diode
indicates the presence of power supply.

2. Soldering the headers

Before using your click board™, make sure
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.

Turn the board upside down so that
bottom side is facing you upwards. Place
shorter parts of the header pins in both
soldering pad locations.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.

3. Plugging the board in

Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all of the pins are
aligned correctly, push the board all
the way into the socket.

4. Essential features

4-20mA T Click™ with it's ADuM1411,
MCP4921 and XTR116 IC's is ideal for
using in field of industrial process control
and test systems. It serves as interface
between sensors or instruments (connected
to microcontroller) and controlled peripherals
in industrial standard current loop. The
board receives the input digital signal from
the microcontroller and sets the output loop
current (4-20mA).
