BRADCOM DRL-DPM-BKF PC104-DPIO Digital I/O Module
1. Product Description
The BRADCOM DRL-DPM-BKF PC104-DPIO is a compact digital input/output (I/O) module designed for embedded industrial systems that use the PC104 bus standard. It’s mainly used to connect industrial sensors (input devices) and actuators (output devices) to small embedded controllers—common in applications like small-scale industrial automation, embedded monitoring systems, and compact control panels (e.g., for small production lines, test equipment, or portable industrial devices).
With a PC104 form factor, it’s ultra-small and stackable (can be layered with other PC104 modules), making it ideal for tight spaces where standard-sized I/O modules won’t fit. It supports basic digital signal transfer: it collects on/off signals from sensors (like limit switches or photo sensors) and sends on/off commands to actuators (like small relays or indicator lights). It’s built for reliable operation in mild industrial environments, making it a practical choice for embedded systems needing simple, space-saving I/O expansion.

3. System Introduction
The DRL-DPM-BKF PC104-DPIO is a key component of BRADCOM’s “PC104 Embedded I/O System”—a lineup of compact modules designed for small-scale industrial embedded systems. This system typically includes PC104-based controllers, I/O modules (like this digital I/O module), and basic configuration tools, targeting applications where space is limited and only essential I/O functions are needed.
In the system, the module acts as a “signal bridge” between the embedded controller and field devices: it takes digital input signals from sensors, sends them to the controller for processing, and then transmits the controller’s digital output commands to actuators. This system is widely used in embedded automation (e.g., small robotic arms, compact test benches) and portable industrial devices—where miniaturization, low power consumption, and basic I/O capability are top priorities.
