Product Description
Mitsubishi Q68ADI Universal model Redundant Power Supply Module
Q68ADI Description
The Mitsubishi Q68ADI is a high-performance analog-to-digital converter module designed for the MELSEC Q series of programmable logic controllers (PLCs). This module is responsible for receiving standard analog voltage or current signals (e.g., 0-10V, 4-20mA) from field sensors and transmitters, converting them into high-resolution digital values, and making this data available to the CPU for processing and control logic. It is an essential component for industrial automation systems requiring precise monitoring of process variables such as temperature, pressure, flow, and level.
Q68ADI Features
- 1.
High Channel Density: Provides 8 analog input channels in a single module slot, optimizing control cabinet space and reducing system cost per channel.
- 2.
High Resolution: Supports 16-bit high resolution (1/32000 scale), enabling highly accurate measurement of analog signals for precise control applications.
- 3.
Flexible Input Range: Each channel can be individually configured for a wide range of analog inputs, including 0-10V, 0-5V, 1-5V, -10 to +10V DC, 0-20mA, and 4-20mA.
- 4.
Easy Configuration: Settings such as input range selection, scaling, and alarm values are easily configured using the GX Works2 software, eliminating the need for complicated hardware switches.
- 5.
Online Module Change: Supports online module replacement (requires a special function module bus board), allowing for maintenance and replacement without stopping the operating system, which is critical for high-availability processes.
- 6.
Diagnostic Functions: Includes error detection functions such as disconnection detection for the 4-20mA range and alarm output for set values, aiding in quick troubleshooting and system reliability.
Q68ADI Material & Applications
- •
Material: The module is constructed with a robust metal casing (for EMI shielding and durability) and a high-quality plastic front cover. The terminal block is typically heat-resistant thermoplastic.
- •
Primary Applications:
- •
Process Control: Monitoring and control in chemical, pharmaceutical, and food & beverage industries.
- •
Factory Automation: Reading signals from analog sensors for position, force, or pressure in automotive and machinery manufacturing.
- •
Environmental Monitoring: Measuring variables like temperature, humidity, and water quality.
- •
HVAC Systems: Controlling temperature and pressure in building management systems.
