elmex Component Housings act as simple Interface Circuits duly mounted in the Terminal Block itself, saving assembly time, cost of wires and labour in the control cubicle. This avoids inter-connection between simple terminals and the components mounted on a separate PCB in the panel, offering flexibility. A variety of components like Diode/s, LED, Resistor, Varistor (MOV) are mounted in Insulation Housing of double deck terminals like KUDD4 as required for the application. They find application in PLC, DCS, Machine Tools and other Control & Automation panels. Component Housings offer an alternative to conventional method of connecting terminal blocks with components on a separate PCB in a panel. They act as simple interface circuits duly mounted in terminal blocks, saving time and labour. The variety of Component Housings for mounting Diode/s, LED, Resistor, MOV in various combination are available using insulation housing of KUDD4.
