N321S-RS485-24V Differential Temperature Controller with RS-485, 12 to 30 VDC Powered

The N321S is a controller for solar heating applications. It typically commands a water circulation pump through the temperature differential between the solar collector and the thermal reservoir or pools.

The controller has two inputs for NTC-type temperature sensors (supplied with the controller) and one control outlet for activating the water circulation pump.

It also includes functions for preventing damage to during deep winter and high summer, thereby preventing plumbing damages (burst pipes) and thermal discomfort.

RS-485 serial and the Modbus RTU protocol allow the N321S to be queried or controlled from a PC, PLC or SCADA system. They come with CE (European Union) and UL (United States and Canada) certifications compliant.
