The disconnection ability of the 237A and ABS module allows components to be inserted into circuits to attenuate, terminate or impedance match without having to re-wire. Test plugs allow access to the circuits between the equipment and jumper sides of each module.
Empty plug cases
Users can make up their own units in blank plugs type 4 pole 440A and 6 pole ABS version. For use with 237A and ABS modules only.
Termination resistances LRU 1A
Resistive termination achieved simply by inserting the appropriate value termination plug type LRU 1A onto the module. Suitable for either 237A, 237B or ABS modules and available in 75 or 600 ohm values as standard.
