Product Description:
The X20SM1436-1 module is produced by B&R Automation for the X20 Fieldbus Input/Output Modules series. Designed as a combined motion and I/O slice, it ties a motor connection and several control signals directly to the X20 backplane and the field network. Within an automation cell, the module functions as a compact node that receives logic commands, captures sensor states, and forwards drive current to the attached motor. This arrangement helps place motion control near the machine section where actuators and sensors are installed, which keeps distributed layouts compact and organized.
At the power stage, the module can deliver a continuous load of 2.5 A, allowing it to run small stepper or servo units without external amplifiers. To protect wiring and limit heat during standstill, the control logic applies current reduction after the motion axis has settled. Sensor interfacing is handled through a dedicated digital input block rated for 24 VDC, and the input channels are isolated to prevent ground loops. With 4 configurable inputs available, the slice can accept limit switches, homing sensors, or start signals directly. For rapid accelerations, the output stage can momentarily supply 3.5 A of peak current so torque can rise quickly during short dynamic moves.
The motion-feedback side is addressed through an integrated incremental encoder interface, enabling closed-loop speed verification without extra wiring. A single plug secures the 1 motor connection and keeps the wiring layout straightforward in multi-axis cabinets. The supply bus accepts incoming voltages up to 48 VDC and continues operating when the source varies by ±25%, which gives the module tolerance for shared supplies and long cable runs. This operating range supports installation in decentralized machine sections where one axis and several local signals must be handled from the same slice.
