I2C OPTO 5-30V PCF8574A

I2C-IN830MA1






I2C OPTO 5-30V PCF8574A

I2C-IN830MA1


This is 8-channel opto-isolator board for input expander over I2C bus. Each input accepts 5-30VDC. It is suitable for solid-state switching devices such as proximity switches. The board uses PCF8574A I2C chip. It supports 100KHz bus speed and 3.3-5.5VDC bus voltage. The board has three jumpers for setting own address. So boards can be connected up to 16 boards on a bus. Also there are I2C bus pull-up resistors and interrupt pull-up resistor on board. They can be enabled by jumpers.
The board can be placed on DIN rail PCB holder which can be plugged on a tray.

The difference between I2C-IN830M and I2C-IN830MA is I2C chip. The I2C-IN830M uses PCF8574 but the I2C-IN830MA uses PCF8574A. And the difference between PCF8574 and PCF8574A is I2C bus address.

Features:
  • PCF8574A I2C chips
  • Support 100kHz I2C bus frequency
  • On-board I2C bus pull-up resistors
  • Address by 3 jumpers for use of up to 8 addresses
  • Up to 16 boards on a bus, (use with I2C-IN830M)
  • Interrupt output signal
  • On-board interrupt pull-up resistor
  • Compatible with most microcontrollers
  • 8 Optically isolated digital input channels
  • 5-30VDC input voltage
  • 3700VDC isolation input voltage
  • Operating power supply voltage 3.3-5.5VDC
  • Inverse polarity protection circuits
  • DIN-rail supports
  • PCB size 42.50x72.00mm

Includes:
  • 1x Board

Notes:
  • This package does not include Din-Rail PCB holders and cables.
  • This board uses 5-pin connectors for I2C bus.
