- SDI-12 controlled 4 channel latching relays.
- Allows remote activation/deactivation of external devices via SDI-12 commands.
- Configurable timers for delayed on/off control per channel.
- Low power consumption due to latching relay design.
- Maintains relay state even after power interruption.
- Supports independent timing settings per channel.
- Designed for environmental monitoring & data logging systems.
- Optional DIN-rail or IP67 enclosure for rugged applications.
TBSRB01
4 CHANNEL SDI-12 Controlled Latching Relay & Timer
The TBSRB01 is a 4 channel relay board with SDI-12 interface. The board is equipped with Schrack latching relays to achieve very low power consumption for application in solar and battery powered systems. A short current pulse is sufficient to toggle the switching contacts of the relay. The switching contacts can be set and queried through SDI-12 commands. An on board RTC offers independent timer functionality for each channel. The relays can be switched independently or simultaneously.
