Description

Important! Note “Header Type” and “Terminal Block” Options above for selecting pin header! See “Pin Headers” and “Order Code” sections below for details.

The im3O module (breakout board) has 3 Opto Coupler inputs, using the high quality LTV-814H.

The inputs are bidirectional, meaning they can have any polarity (+ and – can be on any input pin). An input voltage above about 1.9V will turn the output on (inverted output, ‘on’ = 0V). The input voltage should not exceed 50V. Higher input voltages are possible by placing a resistor in series with the input, but is at your own risk!

The outputs are open collector, and have on board pull-up resistors that can be connected to 3.3V or 5V via a solder jumper located on the top of the board (marked “3V” and “5V”). For example, if the “5V” side of the solder jumper is made, the output will be 5V with no input, and will drop to 0V when the input rises above 1.9V.

The 3 outpus are available on pins marked ‘1’ to ‘3’. If the outputs are connected to a Microcontroller port with built in pull-up resistors, these on board pull-up resistors might not be required (no solder jumper has to be made). Output 2 can additionally be connected to pin marked ‘B’ by shorting solder jumper SJ1. Output 3 can additionally be connected to pin marked ‘C’ by shorting solder jumper SJ2.

This module is designed and manufactured by Modtronix! Only high quality components from reputable suppliers are used! This is NOT a cheap module using no-name components! See “High Quality Components” section below for component details.

The inputs for the 3 opto couplers are available via a 6 pin, 3.5mm Terminal Block connector (if selected via “Terminal Block” option above). Each input has 2 pins, which can accept a voltage up to 50V (any polarity).

To use this board with 5V circuitry, do the following:

  • Supply 5V power to the pin header pins marked 0V and 5V
  • Ensure solder jumper marked “5V” on front of board is made, and solder jumper marked “3V” is open!
  • Connect up to 3 inputs to “IN1”, “IN2” and “IN3” inputs (inputs can hava any polarity)
  • Outputs are available on pins marked “1”, “2” and “3” (5V with no input, drops to 0V when input rises above 1.9V)

To use this board with 3.3V circuitry, do the following:

  • Supply 3.3V power to the pin header pins marked 0V and 3V3
  • Ensure solder jumper marked “3V” on front of board is made, and solder jumper marked “5V” is open!
  • Connect up to 3 inputs to “IN1”, “IN2” and “IN3” inputs (inputs can hava any polarity)
  • Outputs are available on pins marked “1”, “2” and “3” (3.3V with no input, drops to 0V when input rises above 1.9V)

This board is part of our iMod product range, and can very easily be added to any of our products that have iMod ports.

The im3OC has two rows of standard 2.54mm (0.1″) pin headers. The rows are 0.7″ apart, allowing this module to be mounted on a breadboard or standard 0.1″ grid prototype board. The picture to the right shows some iMod modules mounted on a standard prototype board.

The pin headers supplied or soldered to this board are selected in the “Header Type” option at the top of this page.

Pin Headers

By default this board is supplied with No Pin Headers! The following additional options can be selected in the "Header Type" Option at the top of the page (below price):

 

No Pin Headers

No pin header is assembled or included with the board.

Loose 3, 4 and 6.0mm Pin Headers
Click to enlarge

Two unsoldered(loose) Pin Headers are supplied with the board for free. The pin(mating) length is 3.0, 4.0 or 6.0mm. The number of pins depends on the iMod board. For most boards two 1x6 pin headers are supplied.
- Select 3.0mm if module is going to be soldered into place.
- Select 6.0mm if module is going to be plugged into standard 8.5mm high Female Socket.
- Select 4.0mm if module is going to be plugged into low profile 5.7mm high Female Socket.

3.0mm Pin Headers

Pin headers with 3.0mm long pins are assembled. Select this option if the module is going to be soldered into place. The picture on the right shows an example of an iMod module soldered onto a main board.

Header size (2 to 8 pin) depends on iMod board. Many boards will get a 2 pin header on one side, and a 4 or 5 pin on the other.

4.0mm Pin Headers

Pin headers with 4.0mm long pins are assembled. Select this option if the module is going to be plugged into a low profile 5.7mm high female socket (2.54mm grid).

Header size (2 to 8 pin) depends on iMod board. Many boards will get a 2 pin header on one side, and a 4 or 5 pin on the other.

6.0mm Pin Headers

Pin headers with 6.0mm long pins are assembled. Select this option if the module is going to be plugged into a standard 2.54mm female socket.

Header size (2 to 8 pins) depends on iMod board. Many boards will get a 2 pin header on one side, and a 4 or 5 pin on the other.

Round Swiss Pin Headers
Click to enlarge

Two 6 Pin headers with Round (Swiss) style pins are assembled. Select this option if the module is going to be plugged into female Round (Swiss) Sockets. This is very useful for prototyping! See picture on the right for some examples.

Typically the 6 pin female socket (low profile version) can be used for the main board.

We stock a range of swiss pin headers, available here.

Press-Fit Headers

Press-fit type pins are assembled. They can be pressed into 1.00mm holes on a 1.6mm thick (standard PCB thickness) target board. A press-tool might be required for production assembly. Once fitted to the target board, the board is very secure, and can not be removed by hand any more. The picture on the right shows an example of an iMod module mounted onto main board via press-fit connectors.
