Product Description:

The 7XV116.50-11 is an I/O expansion module built by B & R Automation for the 7XV Remote Valve Terminals series. It is intended to source discrete control signals from a compact field node and route them to pneumatic or hydraulic valve islands in automated machinery. Integrated into the terminal stack, the module receives its operating power through the backplane bus and contributes sixteen additional driver channels that help sequence cylinders, clamps, or other final elements.

The board presents 16 digital outputs that are energized by a high-side driver stage rated for a continuous 0.1 A per channel. Each output switches the common supply line at 24 VDC, allowing direct actuation of solenoids without an intermediate relay. A maximum switching cadence of 100 Hz supports rapid on/off cycles required by pick-and-place tooling. Because the driver sources current, it is classified as a high-side driver (source), simplifying wiring when loads share a grounded return. All channels are electrically isolated from the logic domain, and built-in short-circuit, overload, and over-temperature protection shut the stage down when fault limits are exceeded. The module docks to the host through an 11-pin bus connection, while an 11-pin male multipoint connector provides the user interface for field wiring; dedicated ground reference points are available on pins 22, 23, 24, and 25.

An enclosure rating of IP20 limits the module to clean cabinet spaces, and the assembly draws a combined 1.6 A when every channel is at full load. Mechanical size is kept to 63 × 59 × 20 mm, so multiple cards can be lined up on the 25-pin DSUB rail that fastens with 4-40 UNC screws. Despite the steel shield and isolation barriers, overall mass stays at just 56 g. This low weight eases installation on DIN carriers powered directly through the system bus.
