ABB DDI01

The ABB DDI01 is a digital input module that is part of the ABB Freelance DCS (Distributed Control System) product line. It is designed to be used in industrial automation applications where digital signals need to be monitored and controlled. The module has 8 channels, each of which can be configured as a discrete input or a pulse input. The discrete inputs can be used to monitor the status of switches, sensors, and other digital devices, while the pulse inputs can be used to count pulses from devices such as flow meters or tachometers. The module communicates with the Freelance DCS system via a serial communication link and is powered by a 24V DC power supply. It is designed to operate in harsh industrial environments and is capable of withstanding high levels of electrical noise and vibration.
