The PPSSR-16 board is a 16-channel digital output board featuring solid-state relays. If you put the jumper between the SRCLR and WD lines, then holding the WD_LATCH line low will force the SRCLR line low for as long as the WD_LATCH is low. This is why the large delays are present in this code. Numato’s URMC16 16 Channel USB Relay Module provides exceptional value for money. I did so because it was cheap and I had no idea what I was doing. Response must be less that 100,000 characters. Then i used following commands in terminal: *> gpio mode 0 out // Relay switched *> gpio write 0 0 // nothing happend *> gpio write 0 1 // nothing happend I also got a 16 channel relay board. This pin controls the state of the TPIC6B595 shift register clear signal. If the jumper is on the SRCLR and RST pins, then the SRCLR line is only low while the DS1834 RST output (5V or 3.3V, depending on the DS1834SEL jumpers) is low. 240VAC. The DS1834 is programmed with a 10% tolerance. In particular, with the jump in this position, holding the WD_LATCH signal low does not force the SRCLR line low.
