ABB DI814 Digital Input Module

Description

The ABB DI814 Digital Input Module is a high-performance component designed for industrial automation control systems, built on ABB’s fifth-generation digital input technology. It features 16 isolated input channels, split into two groups of 8 channels each, and is compatible with DC 24V/48V input voltages, with an operating input range of 18 to 30V DC and a 6 mA input current at 24V. Key technical specifications include 3000V AC channel-to-channel isolation for 1 minute, delivering strong anti-interference capability, and an ultra-fast 0.1ms response time to support high-precision signal capture. With a low power consumption of 2.5W, it operates reliably across a wide temperature range of -25 degrees Celsius to +70 degrees Celsius, suitable for harsh industrial environments. The module measures 102mm deep, 119mm high, 45mm wide, and weighs 0.2kg, and is compatible with terminal units TU810, TU812, TU814, TU830, TU833, and TU838. Additional features include built-in intelligent diagnostics, patented contact protection technology with over 10 million contact cycles, flexible configuration options, and seamless compatibility with other ABB automation equipment. Ideal applications include signal collection in petrochemical explosion-proof zones, remote hydropower station monitoring, and smart manufacturing production line equipment status monitoring, where it enhances fault location speed, reduces false alarm rates, and improves equipment utilization.
