Intelligent current monitoring

LÜTZE Weinstadt has extended the modular and rail-mountable housing system LCOS by the 10A DC current monitoring LCOS-CC.

LÜTZE offers the current monitoring LCOS-CC in two different versions: as a 1-channel and a 2-channel version. The central advantage of the LCOS-CC is the direct load connection to "+" and "–". In accordance with the housing philosophy of LCOS Systems, all terminal blocks are pluggable, and therefore suitable for tool-free construction or module replacement. The wiring expenses are thus substantially reduced in comparison to conventional systems. On the input side, the nominal voltage of the LÜTZE LCOS-CC totals DC 24V.

In the 2-channel design, the direct connection of the load is duplicated. Status messages take place as optical and electrical signals for each channel separately, either as collective fault messages or on achievement of the 90 percent utilisation. The 2-channel version has a galvanically isolated remote input for the switch-on and switch-off of each channel as well as an independent adjustment of current range and characteristics.

In the one-channel version, the direct connection of the load is quadrupled. In this way it may be possible to do without an additional distributor terminal. Load switch-off takes place 2-pole (+ and -) and is galvanically isolated. This makes use in IT supply networks possible – insulation measurements can be conducted. In this version, both the status message, the 90% status message and the remote input for switch-on and switch-off are each galvanically isolated.

Background to modular LCOS housing system

With LCOS, LÜTZE has developed an IP20 housing system which can be extended through tool-free plug-in of data and/or energy modules to form a complete and modular I/O system. The LCOS electronic housing is based on a device carrier that holds the separate housings or the plug-in function units. Plug-in data or power modules with supply options can supply power to the system and permit the construction of a modular data or power bus.
