Ritron TeleSwitchHP® High Power Wireless Switch Control 136-174MHz | RIT-DTX-165-0BN30I-SIG

The TeleSwitchHP is a versatile, purpose-built, high-power radio initially designed for use in the railroad industry. The radio transceiver (VHF or UHF band) includes built-in, dual DTMF decoder-controlled relays. It can be used as the radio transceiver in a railroad wayside defect detection announcement system. The added remote-controlled relay feature allows the locomotive engineer to initiate "on-demand" the re-broadcast of a recent defect detector announcement message. This feature also allows DTMF remote control of a wide variety of other devices.

The TeleSwitchHP (High-Power) is a 30W (adj. down to 5W), PC programmable transceiver with the added functionality of two built-in DTMF decoder-controlled 1A dry-contact relays. Each relay can be independently controlled by a unique DTMF command consisting of up to 12 characters. Each relay can be programmed to respond as follows: close relay, open relay or perform a momentary closure. An "Acknowledgment Tone" provides an audible tone whenever a command is correctly decoded by the TeleSwitchHP. The dual-color (red/green) LED indicator will light to indicate that the unit is transmitting or receiving.
