Leckmaster 155 relay for JOLA leak detectors

Description

The Leckmaster 155 relay for JOLA leak detectors can be used to detect and signal leaks in electrically conductive and non-conductive liquids. The relay is suitable for installation in clean environments. The switching device is designed to be installed in a protective enclosure or cabinet.

• for connecting 5 CPE, OWE 2/C or COW capacitive sensors
• with cable disconnection control function
• with a touch button to acknowledge the alarm
• with two potential-free switching contacts at the output and
• with 5 20 V DC status signal outputs for building control system

Capacitive relay in upgrade housing, with transparent cover, with 5 x 3 LEDs to show operating status and 1 LED to show N-clear status, inside housing

Features of the Leckmaster 155

• supply voltage: 230 V AC other voltages on request
• Energy consumption: approx. 3 VA
• Sensor circuit: 5 terminals under safety extra-low voltage, for 5 signal lines without galvanic isolation from each other, with common earth connection.
• No-load voltage: DC 8.4 V (safety very low voltage)
• short-circuit current: < 10 mA
• response sensitivity: 1.5 mA 1.8 mA
• cable break monitoring: I < 0,15 mA
• first voltage circuit: 1 single-pole potential-free switching contact based on the operating current principle, for collective alarm in case of leakage or cable breakage, can be confirmed by touch key
• Second voltage circuit: 1 single-pole potential-free switching contact, based on the quiescent current principle, for group alarm in case of leakage or cable breakage
• breakdown voltage: max. AC 250 V
• switching current: max. AC 4 A
• switching power: max. 500 VA
• Status signal outputs for the building control system: 5 connections under safety extra-low voltage for a binary switched-state output signal of 20 V DC of each of the 5 signal lines, without galvanic isolation between them, with a common earth connection
• No-load voltage: 20 V DC (sufficient for 24 V inputs, as a high signal usually requires at least 15 V)
• short-circuit protection: short-circuit current limit ≤ 30 mA
