if by dry you mean relay/switch contacts, then you could make a part by pulse generater mode @ 60hz into driver and a relay, crude but will work.

Need clarification here. 

Are the pulses FROM the PIC, or headed TO the PIC?

Do we want to be sure they are 60 per second or Huh?

you should have to connect the resistor from 'NO' contact to Ground in order to make the real clock of high and low pulses, by reading the schematic i have observed that CLK pin receives only high pulse not low pulse, the state is not chaning from high to low and then low to high.
