DC Bidirectional Voltage Sensor, ±50mV to ±1000V

A DC bidirectional voltage sensor is an isolated voltage transducer designed to measure both positive and negative DC voltages and convert them into proportional analog voltage or current signals for monitoring, control, and industrial automation systems. Using photoelectric isolation technology, it ensures safe separation between input and output circuits, reducing noise and improving measurement accuracy and system reliability. The SUCH DC bidirectional voltage sensor supports a wide range from ±50mV to ±1000V with selectable outputs including DC 2.5±2.5V, 5±5V, 12±8mA, and 10±10mA, making it compatible with PLCs, data acquisition systems, battery management systems, renewable energy equipment, and DC power distribution applications.

Feature

• Wide Bidirectional DC Voltage Measurement — Covers ±50mV to ±1000V with multiple selectable ranges, so the same sensor model can be used across different voltage levels without needing separate devices for each application.
• Multiple Analog Output Options — Offers both voltage output (DC 2.5±2.5V or 5±5V) and current output (12±8mA or 10±10mA), making it straightforward to connect with most PLCs, data loggers, and industrial controllers without additional signal conversion.
• 2.5kV Photoelectric Isolation — Input, output, and power supply circuits are fully isolated, which keeps electrical noise and ground loops from affecting measurement accuracy — particularly useful in environments with variable loads or switching equipment.
• High Accuracy — Rated at 0.2% F.S. for voltage output and 0.5% F.S. for current output, suitable for applications where measurement drift could affect system decisions.
• Fast Response Time — Voltage output models respond in ≤15μs, making them usable in systems that need near real-time voltage tracking, such as active power management or fault detection.
• Wide Power Supply Compatibility — Accepts DC 12V, 15V, or 24V, so it can run directly off existing control panel power supplies in most installations.
• Flexible Mounting — Fits standard DIN rails (NS35/7.5, NS35/15, EN50022) or M3 screw fixation, accommodating both new panel builds and retrofits.
• Industrial-Grade Reliability — IP20 rated with a fire-retardant ABS housing, rated for −25°C to +70°C and MTBF >50,000 hours, designed to run continuously in demanding industrial environments.
