Transmitter EC28 DAB

Product catalog summary

Overview: The EC28 DAB Transmitter is designed for monitoring toxic gases, oxygen, and hydrogen in potentially explosive atmospheres. It features local display of current measured values, digital transmission, and on-site alarms. The device is ATEX-certified and complies with the European Functional Safety Standard DIN EN 61508-2: 2011.

Specifications: The transmitter uses electrochemical sensors and supports a wide range of gases with varying Safety Integrity Levels (SIL). It operates within a temperature range of -20 to +50 °C in Ex zones and -25 to +50 °C outside Ex zones. The device is housed in plastic with IP64 protection and weighs 800 g.

Communication and Service: Communication is facilitated via RS-485 with Modbus protocol. The Smart Sensor technology allows for easy sensor replacement, and adjustments can be made using the RC2 remote control.
