Product Description
Q68AD-G Mitsubishi Universal model Redundant Power Supply Module
Q68AD-G Description
The Mitsubishi Q68AD-G is a high-performance analog-to-digital (A/D) conversion module designed for the MELSEC Q Series of Programmable Logic Controllers (PLCs). This module is engineered to receive analog voltage or current signals from field instruments (such as sensors and transmitters) and convert them into high-resolution digital values for processing within the CPU. It is a critical component for industrial automation applications requiring precise monitoring and control of process variables like temperature, pressure, flow, and level. The Q68AD-G offers high accuracy, fast conversion speeds, and robust reliability, making it suitable for complex and demanding industrial environments.
Q68AD-G Features
- 1.
High Channel Density: Provides 8 analog input channels in a single module slot, saving space in the PLC base unit.
- 2.
High Resolution: Offers a exceptional resolution of 1/60,000, ensuring highly accurate digital representation of analog signals for precise control.
- 3.
Flexible Input Ranges: Supports a wide selection of analog input ranges, including:
- •
Voltage: -10 to +10 V DC, 0 to 5 V DC, 1 to 5 V DC, etc.
- •
Current: 0 to 20 mA DC, 4 to 20 mA DC (with built込 fault detection for 4-20mA signals).
- 4.
Fast Conversion Speed: Achieves a high-speed conversion of 80 µs per channel, allowing for rapid system response to process changes.
- 5.
Built-in Functions: Includes advanced functions such as scaling, input signal error detection (wire break, overrange/underrange), and sampling processing, simplifying program logic.
- 6.
Easy Setup: Can be easily configured using GX Works2, Mitsubishi's integrated engineering software, for setting parameters without complex programming.
Q68AD-G Material & Applications
