ETC 6212 Water Level

ETC6212 & ETC6215 Water Level Control Modules

Smart Boiler Water Management for Industrial Applications

🔧 ETC6212 – Intelligent Water Level & TDS Control

The ETC6212 Daughter Board delivers advanced, automated water level and boiler water quality management for demanding industrial environments. Designed for seamless integration with the ETC6000 series, it offers high accuracy, comprehensive safety features, and advanced control strategies.

⚙️ Key Capabilities

• Dual 4–20mA Level Probe Inputs
  Enables precise, redundant drum level measurement for increased reliability.

• Integrated TDS & Temperature Monitoring
  Direct support for TDS probes and PT100 sensors for water quality control and thermal profiling.

• Relay Outputs
  Trigger alarms for high/low water levels and support integration with external systems.

• Isolated 4–20mA Output
  Ensures smooth, interference-free communication with supervisory equipment.

• Wide Power Compatibility
  Operates on 24–230 VAC, simplifying installation across various facilities.

• Environmental Protection
  Rated IP40 (indoor) or IP54 (outdoor) for rugged durability.

📊 Control Strategy Support

• Single-Element Control: For stable load systems using only water level feedback.

• Two-Element Control: Adds steam flow input for more responsive regulation.

• Three-Element Control: Incorporates feedwater flow for precision in variable-load environments.

🔄 Automated Blow-Down Functionality

ETC6212 automates the boiler blow-down process based on:

• Measured TDS levels

• Time-based intervals

• Maximum time since last cycle

This improves system hygiene, reduces manual intervention, and prolongs boiler life.

✅ Benefits at a Glance

• Advanced Water Level Control
  Highly accurate dual-probe design with advanced control logic.

• Automated Water Quality Management
  Integrated TDS control ensures consistent water quality.

• Enhanced System Safety
  Alarms and interlocks reduce operational risks.

• Operational Cost Savings
  Reduced maintenance and improved efficiency through automation.

• Environmental Versatility
  IP-rated for both indoor and outdoor conditions.

• Flexible Integration
  CANBus support and analogue outputs for system-wide synchronisation.

🔧 ETC6215 – Cost-Effective Expansion Module

The ETC6215 is a streamlined water level control solution for less demanding systems. It retains essential safety and automation features while offering flexibility for future expansion.

⚙️ Core Features

• Single 4–20mA Level Input
  Provides continuous monitoring of boiler drum levels.

• Digital Inputs
  Supports on/off conductive level switches for alarms and safety cutouts.

• Relay Outputs
  For pump control and high/low water level alarms.

• CANBus Communication
  Seamless data sharing with ETC6000 series controllers and touch-screen HMI.

🔄 Expandability with ETC6211
