Mitsubishi Electric AJ65VBTCU-68DAVN CC-Link Digital-Analog Conversion Unit

Description

Processing high-precision industrial signals within CC-Link network architectures, the AJ65VBTCU-68DAVN functions as a high-density digital-to-analog interface module. This remote device station converts digital inputs from the host controller into analog voltage signals across 8 independent channels. Engineered for installation within control panels, it delivers precise analog references to drive speed controllers, control valves, and actuator systems.

The AJ65VBTCU-68DAVN utilizes high-performance D/A conversion circuitry to complete signal processing at a rate of 1 ms per channel. The electrical design isolates communication lines and analog outputs through photocouplers, while the internal power supply system and analog circuits are isolated via transformer barriers. This high-isolation framework prevents ground loops and safeguards against industrial noise and transient surges in challenging electromagnetic environments.

Features

• 8 independent analog voltage output channels configured via CC-Link communication.
• Flexible digital input processing ranges spanning -4096 to +4095.
• Multiple analog output voltage ranges including 0 to 5 V, 1 to 5 V, -10 to 10 V, and user-defined configurations.
• Fast conversion speed of 1 ms per channel for real-time control applications.
• Galvanic isolation utilizing photocouplers and transformer barrier technology.
• Built-in output short-circuit protection to prevent hardware failure from field wiring faults.
• One-touch connector interface design for swift, solderless wiring terminations.
• Highly reliable design conforming to IEC 61131-2 vibration and shock resistance benchmarks.

Applications

• Speed reference control for variable frequency drives (VFDs) and servo systems.
• Analog position control for proportional valves and pneumatic actuators.
• Integration with remote distributed I/O panels in automotive assembly lines.
• Parameter control in continuous process manufacturing and water treatment plants.

Installation Guidelines

• Mount the unit within an enclosed control panel (minimum Pollution Degree 2 classification) to shield the device from conductive dust and moisture.
• Ensure DIN rail alignment or secure panel mounting is applied. Apply mechanical fixings to limit physical displacement during operation.
• Utilize specified CC-Link Ver.1.10 cables for network hookups to maintain communication line impedance and prevent signal degradation.
• Always route high-voltage primary power lines and analog control signal cables in separate conduits to minimize inductive noise coupling.
• Ensure functional ground (FG) terminals are connected to a low-resistance industrial grounding system.
