4-port universal event sequencer board

In amateur radio sets, an event sequencer is used to switch relays, among other things, to be able to switch from receiving to transmitting.

This 4 port event sequencer is a PTT controlled circuit board with 4 connection ports that switch on and off after each other with a delay. The delayed switching time is adjustable and all 4 ports can supply relays with voltage or short-circuit this port to ground. The PTT is activated by connecting it to ground.

The event sequencer is supplied with a manual with clear connection data and connection examples.
This product is CE and ROHS compliant.
