The TX-123 B Transmitter is used for transmitting switching signals from relay contacts, impulse generators or switches, without the need of installing connection lines. The TX-123 B Transmitter has 3 inputs for isolated contacts.
For each of the three inputs, you can separately select among the 2 transmission modes, switch signal or impulse signal.
With using switch signal transmission, only changes in the TX-123 B input state (ON/OFF) are transmitted to a receiver. At the corresponding receiver, the switching function is derived from the signal received while using the radio link during a short time only.
The duration of the transmission can be set to last between 1s and 10s. This operation mode is suited to send switching commands for light barriers, thermostats, alarm systems, motion detectors, or doors and window contacts, etc.
With impulse signal transmission, the transmission time corresponds to the contact duration. The radio link is used as long as the signal is present. |
