Leckmaster 101/Ex relay for JOLA capacitive detectors

Description

The Leckmaster 101/Ex relay for JOLA capacitive detectors is designed for limit level signalling. They shall be installed in a control cabinet or other suitable protective enclosure. The switches are suitable for use in clean environments.

Capacitive Ex relay for U-rail mounting or surface mounting, with connection terminals on top and 3 built-in LEDs to indicate operating conditions.

The unit is designed to be installed or mounted in a suitable protective enclosure outside potentially explosive atmospheres and can therefore only be installed/mounted in these locations. It is only suitable for use in clean environments.

The Leckmaster 101 Capacitive Ex Relay / Ex I (M1) / II (1) GD [Ex ia Ma] I / [Ex ia Ga] IIC / [Ex ia Da] IIIC is designed to transfer control commands from an intrinsically safe control current circuit to a non-intrinsically safe active current circuit. It must be installed outside potentially explosive areas in accordance with the relevant standards and regulations.

An Ex-approved capacitive sensor such as our capacitive COW/Ex-1G, COW/Ex0G, OWE/Ex-1G, OWE/Ex-0G or OWE 2/C/NL/Ex-1G can be used through the device. Mandatory Ex junction box OAK/LMT/2x1MW II 2 G Ex ia IIC T6 Gb, in a safe control circuit. The different application options and specific conditions for safe use are described in the relevant installation, operation and maintenance instructions (sent on request).
