Module 13.2 4IN8OUT

SKU:M122

Description

MODULE 13.2 4IN8OUT is a '4-Channel Passive Input/Switch + 8-Channel MOS Drive Output' drive module. Adopt STM32F030 as the I2C IO chip, support 9-24V DC input, with internal DC-DC circuitry to 5V.

Product Features

• Compatible with Basic/Fire/Core2/CoreS3
• Adopt STM32F030 as the IO chip, I2C communication, I2C address is changeable by modifying the register
• 8-channel MOS Drive circuitry share the same VCC, channle load <1A
• 4-channel Passive Input share the same GND, no active signal or >5V signal allowed
• With internal MP1584, 9~24V -> 5V DC-DC converter

Include

• 1x MODULE 13.2 4IN8OUT
• 13x 2P Terminal

Application

• Multi-channel load drive (Relay, Valva, Single-phase Motor, Singal LED)
• Limit Switch or Button test
