7DO721.7
The 7DO721.7, produced by B & R Automation, is a robust digital output module engineered for industrial automation. Equipped with four high-current relays, it supports switching for 240VAC or 24VDC loads, accommodating devices like motors and heaters with a current capacity of 4 Amperes per channel. Its design incorporates a snubber to mitigate voltage spikes, extending relay longevity to over 200,000 operations. The silver cadmium oxide contacts endure heavy cyclic use, while compliance with CE, UKCA, and UL/cUL standards ensures global suitability. Compact DIN rail mounting optimizes panel space, and the module operates efficiently from 10 to 30 VDC and within temperatures of -25 to 60°C. Onboard intelligence and diagnostic LEDs improve safety and integration, making it ideal for challenging environments. Its durable metal housing and removable connectors enhance reliability for machine builders and system integrators aiming to perform critical AC/DC control tasks efficiently.
