Product Description

Universal model Redundant Power Supply Module Q68DAIN

Q68DAIN Description

The Q68DAIN is a high‑performance 8‑channel digital‑to‑analog (D/A) converter module designed for programmable controller systems. It converts digital control values into precise analog current signals (0–20 mA DC) for driving field devices such as valves, actuators, and indicators. Supporting both standard and high‑resolution modes, it delivers fast conversion speed and accurate control in industrial process and motion control applications.

Q68DAIN Key Features

8‑Channel Current Output: Provides 8 independent analog current outputs (0–20 mA DC) for multi‑loop control.
Dual Resolution Modes: Standard resolution (–4096 to +4095) and high resolution (–12288 to +12287) for enhanced precision.
Fast Conversion Speed: 80 μs per channel, enabling rapid response in dynamic control systems.
High Accuracy: ±0.1% (25°C) and ±0.3% (0–55°C) full‑scale error for reliable performance.
Output Short‑Circuit Protection: Built‑in protection prevents damage from accidental short circuits.
Isolation Design: Photocoupler isolation between I/O and controller power; transformer isolation for analog output.
Compact Form Factor: Space‑saving design with 18‑point terminal block for easy wiring.
Long‑Term Reliability: E2PROM supports up to 100,000 write cycles for configuration storage.

Q68DAIN Materials & Applications

Materials

Housing: Flame‑retardant ABS plastic, impact‑resistant and dust‑proof.
Circuit Board: FR‑4 fiberglass epoxy with conformal coating for moisture and corrosion resistance.
Terminals: Nickel‑plated copper alloy, suitable for 0.3–0.75 mm² wires.
Power Components: High‑efficiency DC‑DC converters and surge protection devices.
Connectors: Industrial‑grade pin headers for stable backplane connection.

Typical Applications

Process Control: Analog control of flow, pressure, and temperature in chemical, water, and HVAC systems.
Motion Control: Speed/torque command for variable‑frequency drives and servo amplifiers.
Valve & Actuator Control: Precision positioning of proportional valves and pneumatic actuators.
Instrumentation: Driving analog indicators, recorders, and panel meters.
General Automation: Any system requiring digital‑to‑analog conversion for 0–20 mA current signals.
