DLP Design DLP-IO8-G USB-Based 8-Channel Data Acquisition Module

The DLP Design DLP-IO8-G is a USB-powered 8-channel data acquisition module for industrial and laboratory applications. Each channel configures independently as a digital input, digital output, analog input, or temperature sensor interface. Operation is controlled via simple single-byte commands over USB 1.1/2.0, making it suitable for terminal emulation or custom software integration without external power supplies.

## Technical Specifications

• **Channels:** 8 configurable channels
• **Digital I/O:** High/low read and write capability; 25 mA sink/source per channel
• **Analog Input:** 10-bit ADC, 0–5 V range, 4.9 mV resolution (5 V / 1024)
• **Temperature Sensing:** DS18B20+ compatible (sensor sold separately); -55°C to 125°C (-67°F to 257°F)
• **USB Interface:** USB 1.1 and 2.0 compliant; 115200 baud terminal rate
• **Data Output:** ASCII text or binary format selectable
• **Supply Voltage:** 5 V via USB host port
• **Operating Temperature:** 0°C to 70°C
• **I/O Voltage Range:** -0.3 V to +5.3 V with respect to ground

## Key Features

• No external power supply required — USB enumeration and operation from single host connection
• Compact form factor with terminal block connectors for field wiring
• Mixed-mode channel operation — assign pins independently to I/O, analog, or sensor functions
• Single-byte command protocol reduces firmware complexity and enables rapid prototyping
• Immediate ASCII readout via standard terminal emulators or binary data for scripted acquisition

## Typical Applications

• Data logging and process monitoring in benchtop systems
• Digital signal acquisition with simultaneous analog measurement
• Temperature monitoring using one-wire DS18B20+ sensors
• Control logic and relay switching in automated test setups
• Laboratory instrumentation integration without dedicated DAQ hardware

## Compatibility & Integration

Works with terminal emulator software or custom applications in any language supporting USB serial communication. Driver requirements depend on host OS and software package; drivers are included with some distributions or available separately. Requires separate DS18B20+ sensor purchase for temperature measurement channels.
