TRB141 supply through I/O pins


Can the TRB141 be supplied though the I/O “+” terminal, instead of through the “power socket”?
I intend to use the TRB as an SMS-alarm, and have +24V available from the surveillanced machine, but not always a 230V socket nearby for the supplied power supply.

The wiki states that the “+” is directly connected to the power supply input pin, but since it is supposedly to be used for external 4-20mA current sensors, I’m afraid there is some internal limit?

Best regards


Please note that TRB142 cannot be powered using I/O pins; it requires a 4-pin power socket for power. You can find additional information on our wiki: TRB141 Powering Options - Teltonika Networks Wiki.

Best regards,
