| − | Model 7501T8 is a solid-state relay (SSR) rack that accommodates up to eight G4 type SSR modules. It has a 50-pin header which is compatible with several Sensoray GPIO products, including models 826 and 2410.

| − | The relay rack can be connected to header J3 or J2 on the 826 board. The GPIO mapping table (shown to the right) shows the GPIO associated with each SSR. The mapping depends on whether the relay rack is connected to J3 or J2. For example, if the relay rack is connected to J2 then SSR2 will be routed to GPIO26.

| − | You must supply 5 VDC power to the relay rack. This can be done in either of the following ways:
| + | |
| − | * Connect an external 5 VDC power source to the relay rack's +5V and GND terminals.
| + | |
| − | * On the bottom of the relay rack, attach a wire (via solder) from the +5V terminal to J1 pin 49.
| + | |
| − | | + | |
| − | Model 826 has active-low GPIOs, and the relay rack is designed for active-low signaling. Consequently, to turn on an output SSR you must write '1' to the associated GPIO, and write '0' to turn it off. Similarly, when reading an input SSR, '1' indicates the relay is on, and '0' indicates off.
