End holder
The end holder 8WA2808 is snapped onto the rail (EN 50 022) without
screws.
Screwdriver for Cage
Clamp terminal system
The screwdriver 8WA2804 is suitable when wiring coupling links with Cage
Clamp terminals.
End plate
In order to ensure shock protection in the case of the two-tier optocouplers
having a width of 6.2 mm and with a housing opening (e.g. 3TX7 004-
3AB04), the individual module or last module in a series must be fitted with
an end plate 3TX7004-8CE00.
Labeling strip
Each coupling link has a labeling strip for the purpose of identification.
6.4.2 Accessories for LZX plug-in relay coupling links
Retainer
In situations where there is increased mechanical stress, a retainer can be
fitted to plug-in relay coupling links to provide stability.
LED module
An LED can be fitted as an individual plug-in module with the variants LZX:
RT and LZX:PT.
Module with flywheel-
ing diode
A flywheeling diode for surge suppression can be fitted as a module (for DC
voltages) with the variants LZX:RT and LZX:PT.
RC module
For AC voltages, there is a plug-in RC module available with the series
LZX:RT and LZX:PT for surge suppression.
