conductiveprogrammablewith relay output

Overview
The electronic controllers ENR300, ETS100, ETS200 and ETS410 provide precise liquid level control and dry-run/overflow protection for industrial tanks. Designed for integration in surface treatment, electroplating and other industrial processes, these modules offer configurable thresholds and reliable signal interfaces for PLCs.

Key Benefits

• Complete protection: Accurate detection to prevent overflow and dry-running; responsive control with a 3-second switching delay.
• Flexible configuration: Models configurable for MIN/MAX control; ETS410 supports up to 4 independent level inputs.
• Industrial readiness: PA6.6 polyamide housing, DIN-rail mounting and electromagnetic compatibility in accordance with EN 61326.

Main Applications

• Level monitoring and control in industrial tanks
• Protection of chemical processing and electroplating systems
• Integration into automated processes requiring multi-threshold alarms and PLC interfacing

Technical summaries by model

• ENR300: Relay output (configurable MIN/MAX contact) for level control; additional monitoring of a separate critical level.
• ETS100: 1 relay output for a single switching point (MIN or MAX).
• ETS200: 2 relay outputs for two independent switching points.
• ETS410: 4 inputs to detect up to 4 independent levels; 4 relay outputs for alerts or PLC transmission.
• Adjustable sensitivity: 0.05 to 100 kΩ to match liquid conductivity.
• Sensor compatibility: Float switches and resistive probes.
• Mounting and protection: DIN-rail mounting; PA6.6 housing; IP20.
