Process Control & Industrial Automation Solution – Mitsubishi A616AD | MELSEC-A Series
Where This Product Is Used
The Mitsubishi A616AD is a 6-channel analog-to-digital (A/D) converter module designed for the MELSEC-A Series programmable logic controller platform. It is widely deployed across demanding industrial environments where precise analog signal acquisition is critical:
- Chemical & Petrochemical Plants — monitoring temperature, pressure, and flow sensors in continuous process loops
- Automotive Manufacturing — real-time feedback from torque sensors, load cells, and position transducers on assembly lines
- Power Generation & Utilities — acquiring 4–20 mA current loop signals from field instruments in SCADA-integrated substations
- Food & Beverage Processing — temperature and level monitoring in CIP (Clean-In-Place) and pasteurization systems
- Steel & Metal Processing — tension control and furnace temperature regulation in rolling mill automation
- Water Treatment Facilities — pH, turbidity, and dissolved oxygen sensor integration into PLC control loops
- Semiconductor Fabrication — precision analog data acquisition in cleanroom process equipment

Application-Specific FAQ
Q: Can the A616AD be used with AnS-Series (compact) base units?
A: Yes. The A616AD is compatible with both standard A-Series and AnS-Series base units, making it suitable for both large and compact MELSEC-A system configurations.
Q: Can I mix voltage and current inputs on the same module?
A: Yes. Each of the 6 channels can be independently configured for either voltage or current input via the module’s parameter settings in GX Developer or GX Works2.
Q: What is the maximum cable length for analog field wiring?
A: Mitsubishi recommends shielded twisted-pair cable up to 200 m for current input (4–20 mA) and up to 30 m for voltage input to maintain signal integrity.
Q: Is the A616AD still in production?
A: The MELSEC-A Series has reached end-of-production. However, Konmask.com maintains stock of genuine A616AD modules to support legacy system maintenance and plant life extension projects.
Q: Do you provide a warranty?
A: Yes. All modules sold by Konmask.com carry a 12-month warranty against manufacturing defects. Replacement or full refund is provided for verified defective units.
