When an Intermatic ET90000 astronomic lighting controller needs more circuits, or a relay board has failed, this is the factory part. The Intermatic ET9250 is a 4-circuit relay board for upgrading or replacing relays in ET90415CR through ET91615CR panels, adding boards in 4-circuit steps up to 16 circuits. Each board ships as four independent SPDT relays, and jumpers let you pair them.
Why controls contractors pick it
- Factory Intermatic relay board for ET90000-series panels, so the controller recognizes it directly.
- Adds four circuits at a time to grow a panel toward 16 circuits.
- Default four independent SPDT relays; jumpers JP1 and JP2 pair relays when a load needs it.
- Relays rated 30 A with a 120/277 VAC coil (per Graybar listing).
- Takes #14 to #6 AWG copper conductors rated 90°C.

Pro tip from the counter
When you pair relays with the JP1/JP2 jumpers, the even-numbered relay of each pair drops off the controller display. Program schedules only on the odd-numbered outputs and relabel the panel directory, or a later tech will go looking for a missing channel.
Best for: expanding ET90000 lighting controllers, replacing failed relay boards, parking lot and building lighting schedules, facility maintenance and controls contractors
