This product uses the double-signal relay，Having one set of coils，2 sets of normally open and normally closed synchronous control relay.
This module has an 8-way trigger 16 normally open and normally closed control, often used in single-chip signal control, low current motor reversing control, PLC control, etc., it can also be used to develop the use of Arduino accessories.
HK19F type using double signal relay. Only 8-way trigger input, but there are 16-way switch output.
The output of the relay with a 16-way common, normally open, normally closed end, and the 16-way work independently. High-quality high-temperature PA terminals.
Having a relay working status indicator. SS8550 do with the original transistor switch, a large current better quality assurance. The high level trigger module, which uses DC positive trigger.
