We are considering using the following ProXR relay controller boards:
- 32 channel DPDT, 1A relays, with RS485 communications module
- 32 channel DPDT, 3A relays, with RS485 communications module
- 8 channel SSR, type H (CMX100D10?) with RS485 communications module
All boards will be connected to a single RS485 controller.
Will these boards operate over the temperature range -20 to +55 deg. C ?
