The F-325X "filament" transformer used to power the entire board can be reconfigured for 115 or 230v primary voltage and is detailed on the windings themselves. The secondary should be on a 3 pin molex style connector with both wires green. | The F-325X "filament" transformer used to power the entire board can be reconfigured for 115 or 230v primary voltage and is detailed on the windings themselves.

More examination needs to be done, but this module appears to latch the relay for a configured amount of time. I have seen multiple of these on other models that can do more signals such as "Attack" or "Fire", some with more DIP switches populated. | More examination needs to be done, but this module appears to latch the relay for a configured amount of time.

The covered DIP switches | The covered DIP switches of SW1 control parameters of the timing cycle, feeding configuring the 8 bits of the Maxim timer IC. Those bits configure the time delay by connecting each of the pins 1 through 8 on the IC through the a 10kOhm resistor (R3) to VCC. | ||
The DIP switch config for the steady 3 min cycle timer is, from left to right (Up = ON): up, down, up, down, down, up, down, up. This sets pins 1, 3, 6 and 8 high, and 2,4,5,and 7 low (the DIP switch numbers are backwards in reference to the IC pins). This equates to a RC time constant of 165. | |||
Pin 13 of the IC is the RC input which is fed by a 1.1MOhm resistor and a 1uF 35v tantalum capacitor. Cross referencing those values in the datasheet chart, we get a RC timebase of 1Hz. The confusing part is that with these figures, we get a cycle time of 165 seconds, not 180 as 3 minutes would work out to. I will have to try setting switches 8, 6, 5 and 4 high which should equal exactly 180s. | |||
