Limit switch trasmission modules RXTX R25-TK4, TK8, TK16, TK24 type are applied for radio transmission information about state of cooperating cranes’ limit switches.

Additional for version TK xx STOP there is possibility of transmitting signals from STOP switches with bonded contact control and two-way transmission of inputs.

Set consists of two modules, each of modules is placed in a separate housings. Modules has according to version up to 24 inputs, which states are transmitted to second module and mapped with state of appropriate relays.
