Product Description:
The MDA115-0 by B & R Automation is a digital output module suited for automated systems. It functions as a control interface that sends discrete electrical signals to actuators, relays or other field devices, enabling precise execution of commands from the central control system. This module is well-suited for factory automation, machinery control, and process systems where timely and reliable output activation is essential. The module provides isolated switching signals, meaning each output channel is electrically separated from the internal logic circuitry and other output channels. This isolation enhances system stability, ensuring safe operation across all connected components.
The MDA115-0 features transistor-based sourcing outputs, which are designed to deliver a positive voltage to connected loads. They deliver a 24V DC voltage at up to 0.5 amps per channel. The use of transistors allows for fast and reliable switching with minimal mechanical wear, making the module well-suited for applications that involve frequent on/off cycling. This module is designed with microsecond-range switching speed, allowing for extremely fast on/off signal response times. This rapid switching capability ensures that output signals are activated or deactivated almost instantly in response to control logic, enhancing synchronization across devices.
This module comes with built-in short-circuit protection, which automatically detects and interrupts current flow when a short-circuit condition is present on any of the output channels. This protective feature prevents excessive current from damaging the module, connected devices, or wiring infrastructure. In the event of a fault, the module isolates the affected channel, allowing the rest of the system to continue functioning without interruption. By minimizing potential damage and downtime, the module ensures safe operation and extends the lifespan of both the module and connected peripherals.
