B&R Industrial Automation 3DO690.6 Digital Output Module

The B&R 3DO690.6 is an 8‑channel digital output module for the 2005 system, delivering eight 120 V AC triac outputs split into two electrically isolated groups. Each output switches up to 1 A at 120 VAC, with a group rating of 2 A and a total module current of 4 A under a 50% simultaneity factor. The module supports an external sensor power supply and consumes 1.5 W of internal power, with external power usage up to 6 W under typical operation. It operates at 45–63 Hz and is IP20 protected, suitable for indoor automation environments. Operational temperature ranges from 0 to 60°C and relative humidity from 5 to 95% (non‑condensing). Mechanically, it is a single‑width 2005 module designed to plug into the System 2005 backplane and requires a TB170 terminal block (sold separately) for field wiring—options include 3TB170.9 (20‑pin screw clamp) or 3TB170.91 (20‑pin push‑in). Certifications include CE, UKCA, and UL/cULus E115267. In official documentation and product catalogs, it is described as “2005 digital output module, 8 triac outputs, 120 VAC, 1 A, 2 electrically isolated output groups,” highlighting its two‑group isolation and AC switching capability.
