PRODUCT INFORMATION
Product Overview
The ABB DO820 D0820 is an S800 I/O digital output module designed for process automation systems. It provides 8 isolated normally open relay output channels. The unit operates across rated output voltages from 5 to 250 V AC or DC. Each channel supports a continuous output current of up to 3 A. The module delivers discrete switching control for field actuators and interposing circuits.
This unit features an IP20 protection class and requires vertical mounting within an S800 I/O station. It operates within an ambient temperature range of 0 to 55 °C. Storage temperatures range from -40 to 70 °C. The module weighs approximately 0.23 kg and measures 45 mm wide. Its compact design fits standard process control cabinets and field junction enclosures.
