Leckstar 101/S relay for JOLA leak detectors

Description

The Leckstar 101/S relay for JOLA leak 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.

• with cable disconnect control and switchable self-hold
• with separately routed output for cable break monitoring
• for connection of 1 conductive electrode with cable break monitoring unit Z10
• with 2 potential-free interrupting (NC) contacts at the output

Electronic relay for DIN rail mounting or surface mounting, with connection terminals at the top and 3 integrated LEDs to indicate operating conditions

Self-restraint:

• If the Self-hold switch is activated, an alarm is stored. The relay continues to signal the alarm even if the cause of the alarm (e.g. presence of water or cable break) is no longer present – in other words, if the sensor is dry again or if the line is in contact. The alarm is acknowledged by switching off the self-hold switch.
• If the self-hold switch is not switched on, the alarm will not be maintained when the cause of the alarm is eliminated, but will be interrupted.

Features of Leckstar 101/S

• supply voltage: 230 V AC; on request: 240, 115, 24 V AC or 24, 12 V DC
• Power supply: approx. 3 VA
