Product Description
Q62AD-DGH Mitsubishi Universal model Redundant Power Supply Module
Q62AD-DGH Description
The Mitsubishi Electric Q62AD-DGH is a high-speed analog-to-digital converter module designed for use with the MELSEC-Q series of Programmable Logic Controllers (PLCs). This module acts as a critical interface between the digital world of the PLC and the analog world of field instruments. It receives standard analog voltage or current signals (e.g., 0-10V, 4-20mA) from sensors or measuring devices and converts them into high-resolution digital values that the PLC CPU can process for monitoring, control, and data logging applications. It is known for its high accuracy, reliability, and fast conversion speed, making it suitable for demanding industrial automation processes in fields like factory automation, environmental monitoring, and precision machining.
Q62AD-DGH Characteristics
- •
High-Speed Conversion: Capable of converting analog signals to digital values at high speed, allowing for rapid system response to process changes.
- •
High Resolution: Offers 16-bit resolution, providing fine measurement precision and allowing the PLC to detect very small changes in the analog signal.
- •
Multi-Channel Input: The Q62AD-DGH provides 4 independent analog input channels, allowing a single module to connect to multiple sensors, which saves space and reduces cost compared to using single-channel modules.
- •
Flexible Input Types: Each channel can be individually configured to accept different analog signal types, including:
- •
DC Voltage: e.g., 0-10V, ±10V
- •
DC Current: e.g., 4-20mA, 0-20mA
- •
Easy Configuration and Scaling: Settings such as input range selection and scaling are configured easily using the GX Works2 or GX Works3 engineering software, simplifying setup and integration into the control program.
- •
High Reliability: Designed for harsh industrial environments with robust construction and high noise immunity, ensuring stable operation.
Q62AD-DGH Material & Application
- •
Materials: The module is constructed with a robust metal casing and uses industrial-grade electronic components on a PCB. The terminal block is typically made of heat-resistant, flame-retardant plastic.
- •
Primary Applications:
- •
Process Control: Reading process variables like temperature, pressure, flow, and level from transmitters.
- •
Factory Automation: Monitoring analog signals from sensors for position, speed, tension, and weight.
- •
Environmental Monitoring Systems: Measuring data from sensors for humidity, gas concentration, or light intensity.
- •
Test and Measurement Equipment: Digitizing analog outputs from various test apparatus.
