About signal isolaters?
Electronic devices which is used to separate, send, and modify analog signals between control systems and field instrumentation called signal isolaters. They shield your PLCs, DCS, and other delicate equipment from voltage spikes and mismatched signals, stop ground loops, and get rid of electrical noise.
Key Features of Our Signal Isolators
Our signal isolaters are designed to be accurate, long-lasting, and suitable for a variety of industrial settings. Each unit provides best-in-class performance and reliability, whether it is utilized for OEM integration, SCADA panels, or power plants.
Core Features:
- Electrical Isolation up to 2.5kV
safeguards delicate PLC and DCS inputs and avoids ground loop problems. - Universal Signal Compatibility
supports a wide range of common inputs and outputs, including RTD, thermocouple, 0-10V, 0-5V, and 4-20mA. - Compact DIN Rail Mounting
Modern control panels with a space-saving compact DIN rail mounting design. - High Accuracy & Low Drift
guarantees accurate signal transmission even in the face of fluctuations.
- Galvanic Isolation Between Input, Output, and Power Supply
Isolation by Galvanic Cross-interference between circuits is eliminated between the input, output, and power supply. - Signal Conversion & Splitting
Convert current to voltage and vice versa, or divide a single input into two outputs.
