I have been playing with an Arduino Uno r3 for about a week now (thus newbie).
I would like to connect a SSR in order to switch 7 pool lights on and off. The existing analogue timer switch (Theben SYN168A, specs nowhere to be found) for the lights can switch up to 16A (according to the writings on it) and it draws power from a 25A breaker. It switches power to 4 transformers which supply power to the lights (12V, 300W each lamp).
I would like to introduce an SSR (namely the 25A from them http://www.redlion.net/Products/Groups/DIN-RailRelays/RLY6/RLY6A/Docs/12021.pdf) before the timer. I understand that I should use a fuse in order to protect the SSR but I would like to ask if I should do anything about the arduino connection.
The SSR specs for control:
INPUT SPECIFICATIONS 1. CONTROL VOLTAGE RANGE: 4 to 32 VDC 2. TURN-ON VOLTAGE (MIN.): 4 VDC 3. TURN-OFF VOLTAGE (MAX.): 1 VDC 4. REVERSE VOLTAGE PROTECTION: -75 VDC 5. INPUT CURRENT (MAX.): 8 mA
which seem to within the arduino grasp.
Any thoughts would be appreciated!
