Product Description:

The X20SO2120 by B&R Automation is a 2-channel output module designed for use in safety-related applications in industrial automation systems. It offers reliable control of actuators in safety applications by ensuring precise and secure signal switching. This module is suitable for use in applications such as emergency stop circuits and safety doors, supporting compliance with stringent industrial safety standards. The design of the module incorporates 2 safe Type A digital outputs that enable reliable control of actuators such as relays or contactors. These Type A outputs are designed to meet safety requirements for basic safety functions, making them suitable for straightforward safety applications. They come with current monitoring which helps to detect issues like overloads or short circuits in real time.

The X20SO2120 is rated for a OSSD response time of less than 500 µs, which enables it to switch outputs off extremely quickly when a safety condition is triggered. This rapid response enables immediate action to protect personnel or equipment, such as during emergency stops. The module supports a maximum output current of 2 A per channel, providing sufficient power to drive a wide range of safety devices. Its 24 VDC standard ensures compatibility with most industrial control systems, reducing complexity during integration. This unit allows operators to quickly assess the module’s performance via its status display for I/O function per channel, operating state and module status.

The X20SO2120 is designed for use with X20 12-pin terminal blocks, ensuring seamless mechanical and electrical integration within the X20 system architecture. It is designed to be compatible with a wide range of B&R X20 I/O components, allowing for flexible system configurations.
