SKS_RRJ_TRA - SKS TRA Bundle (control unit, reader, transponder)

The SKS TRA is an electronic evaluation unit with 3 potential-free relay outputs and a special housing for quick installation on a standard top-hat rail. Terminal devices can be connected directly via the 3 relay outputs, which is why no external controller such as a PLC or an industrial PC is required to use the SKS TRA. The evaluation electronics have an internal assignment table which is used to determine which relay outputs are switched to the respective transponder and which functions are thus enabled (TRA = Transponder Relay Assignment). The assignment table contains several programs with different combinations of transponder numbers and relay outputs to be enabled. The programs can be set using a rotary switch on the evaluation electronics. The SKS TRA supports two operating modes: cyclical and individual scanning. With cyclical scanning, the presence of the transponder is permanently checked at regular intervals. As long as the transponder is registered, the function switched with the transponder remains active. With individual queries, each new registration of a transponder is evaluated and the associated action is activated. Up to 25 user keys can be managed with the SKS TRA. Depending on the program selected, up to 7 authorization levels are possible for different user groups.
