SVS Nachrichtentechnik SHR-12 K4 4-channel Receiver Max range (open field): 750 m
The radio receiver SHR-12 K4 evaluates each radio signal of the suitable transmitter of the radio series SH-12 and can switch one or more of the 4 potential-free changeover contacts on and/or off.In order to implement the command of a transmitter, it must first be programd once. The programming of a transmitter is done very easily via a button. Depending on your preference, up to 60 stations can be programd with all buttons or individual transmitter buttons.The function to be used by the transmitter buttons or the send command is assigned via a selection field. With the help of DIP switches all settings can be carried out comfortably during the installation on site. Both normally open and normally closed contacts are available for connection. LEDs provide information about the function and transmission behavior and indicate the status of the power supply of the transmitter and the radio receiver.The large number of functions and setting options of the 4-channel multi-function receiver SHR-12 K4 allows the use in the most varied applications. For this purpose, different relay functions can be set separately for each output.Momentary operation: Input and output behave identically. The output is only active as long as ON is sent.Timer operation: After an ON command, the output remains active for the set time and then automatically drops off again. The adjustable time range of the timer is between 0.1s and 60min. Off commands are still implemented.Switching mode: After an ON command, the output remains permanently active until an OFF command deactivates the output again.Toggle mode: A command activates the output permanently. The same command switches the output permanently inactive again, etc.The signal/function assignment also enables the combination of the different relay functions and mutual locks. Regardless of the selected function, the relays can also be controlled by line, e.g. via external buttons, code or key switch.SHR-12 K4 is supplied complete with IP65 housing and built-in bracket antenna ready for connection. If very large ranges are to be bridged, the multi-flex antenna (no. 115142) can be used to supplement or retrofit the multi-function receiver.The radio receivers of the radio series SH-12 work extremely low interference due to their special transmission properties. With the interference-resistant radio transmission with extremely short response times, ranges over 1000m can be achieved.For severe narrow-band interference or the use of several parallel radio systems, the working frequency can be set to suit individual requirements. The SH-12 radio series can be operated both unidirectional and bidirectional. In bi-directional communication, the transmitter automatically adjusts its transmission behavior to the quality of the radio link.This text is machine translated.
