Limatherm Sensor controller with RS-485 communication as an option. It has digital inputs, two outputs for transmitter supply 24V. N3000 has universal input suitable for most popular thermocouple and Pt100 sensors and analogue inputs, including 4÷20mA. Low or standard 230V power supply can be selected. 4 relay outputs programmable as alarm or control, 5th universal output programmable as SSR 14V (for control of three-phase semiconductor relays or 4÷20mA (control or retransmission)), digital input/output.
