This is an updated version of the PTT splitter, which has more outputs and other changes. One of them is the use of SSR relays, which can switch not only DC but also AC current. In addition, the outputs are fully isolated, including ground. The outputs can be connected in series and allow switching of higher open voltages. Power can be supplied via a DC jack or the green screw terminal input. Two LEDs indicate the DC supply voltage and PTT status. The outputs include surge protection and an RFI PI filter.

Applications

You can easily switch multiple devices controlled by a single input. The outputs are isolated.

You can easily connect a twin cable to the green connector and use the outputs 9 and 10 as you would with a relay contacts. You can switch both DC and AC currents.

Contacts 9 and 10 can also be connected in series if you need to switch a device (PA) that has high (open) voltage during RX.

Example of mounting with DIN rail set. This set is not included. It is option and you can buy it at our shop.

DC supply

The entire splitter is an active device. It requires a power supply to function. You can connect a power supply in the range of 12 to 14 V DC in two ways. One option is a round jack, the other is a green screw terminal connector.
