Gas Detection Control Unit ET-1D(A)

Product catalog summary

Description: The ET-1D(A) is a gas detection control unit designed for measuring flammable, toxic gases, and oxygen levels. It features a display with menu-guided configuration, two alarm levels, and relays for alarms, horn, and faults. The ET-1DA model includes an analogue output of 4-20 mA.

Features: The unit supports one transmitter with a 4-20 mA signal. It uses a microcontroller with an A/D converter for signal processing. The display shows measured values, messages, and alarms, with LEDs indicating operation, alarms, and faults. The system is menu-guided, fully configurable without tools, and password-protected. It allows for two adjustable alarm levels and configurable alarm latching. The unit includes four potential-free relays for alarms and faults, and additional features like zero point adjustment and maintenance mode alarm locking.

Electrical Features: The unit operates on 230 V AC or 24 V DC, with a power consumption of 20 W. It conforms to EC Directives 94/9/EC (ATEX), 2004/108/EEC (EMV), and 2006/95/EEC (LVD), and is designed according to DIN EN standards.

Relays Configuration: The relays are configurable for alarms and faults, with standard settings using a closed-circuit principle for alarms and an open-circuit principle for the horn. Custom adjustments can be made by ExTox-Service.

Installation Types: The unit is available in several installation types: wall-mounted, DIN-Rail, control panel, and 19''-rack. Each type has specific dimensions, materials, and installation hints. The wall-mounted and DIN-Rail types have an IP 54 enclosure rating, and the control panel type includes a polystyrene front lid with a double front seal.

Dimensions and Materials: The wall-mounted type measures 160 mm x 194 mm x 90 mm, made of ABS. The control panel type measures 296 mm x 196 mm x 80 mm for the indication/controller, with an I/O-clamp terminal of 160 mm x 160 mm x 40 mm. The 19''-rack type fits a 19'' frame with dimensions of 482.6 mm x 265.35 mm x 185 mm.

Additional Information: The document notes that technical changes are subject to occur.
