Loop Isolator Module LIM
Loop Isolator Module to install a short-circuit and open-circuit tolerant 100 V loudspeaker loop wiring system in VARIODYN ONE loop technology. The modules monitor the current on the loudspeaker loop and disconnect the defective part of the loop in case of over-current, e.g. at a short-circuit. Loop failures are displayed on VARODYN INC (Intelligent Network Controller) and PACT-software. Each module has a total of three two-pole terminals to connect the loop wiring system and the speakers. Wires with a cross-section of up to 2.5 mm² can be connected to the terminals. In addition, each LIM has 3 LEDs to display the operating status. The LIM is housed in a stable, compact IP 66 housing with sufficient wiring space and can be used in projects with difficult environmental conditions, e.g. in industrial applications.
