Technical Specifications
Number of output channels: 4. Output range: 4-20mA. Resolution: 16-bit signed. Accuracy: ±0.2% FS @25°C. Operating voltage: 24V DC. Operating temperature range: -20°C to +60°C. Protection rating: IP20. Mounting style: DIN rail / panel mount.
Functional Features
It delivers 16-bit high-precision output. Each channel has independent short-circuit protection and reverse polarity protection. Channels are electrically isolated from each other. It has fast response time and LED channel status indicators.
Application Scenarios
It is widely used in process control systems, flow regulation, pressure control, temperature control loops, valve actuation, frequency converter control, and continuous production processes in manufacturing industries.
Performance Parameters
Output update time: ≤2ms. Absolute accuracy: ±0.2% full scale. Temperature drift: ±50ppm/°C. Maximum load impedance: 500Ω. Operating temperature range: -20°C to +60°C.
Structural Characteristics
It adopts compact modular design with flame-retardant plastic housing, screw terminal strip, metal mounting clips, layered circuit design, and front panel status indicators.
Working Principle
It receives digital control signals from the PLC bus, converts them into corresponding 4-20mA current signals through D/A conversion circuits, and drives field execution equipment through output channels. The internal isolation circuit ensures signal stability and equipment safety.
Installation Requirements
Mount on DIN rail or panel. Power supply: 24V DC ±10%. Wiring torque: 0.5-0.6 N·m. Total load impedance must not exceed the maximum value. Use shielded cables with single-end grounding.
Usage Notes
Disconnect power before wiring. Install protection components for inductive loads. Regularly calibrate output accuracy. Avoid output short circuit. Keep ambient humidity below 95% non-condensing.
