EM45-SN

EM45

EM45-SN is a Sensor/PID controller with many inputs:

INPUT 1 – TEMPERATURE:

to connect an external PT100 sensor (2 wires).

INPUT 2 – TEMPERATURE:

to connect an external semiconductor type sensor (2 wires), typically in a range: -55°C… +155°C.

INPUT 3 – TEMPERATURE:

to connect an external digital infrared type sensor with I2C interface (4 wires) typically in a range: -70°C… +385*C.

INPUT 4 – DIFFERENTIAL PRESSURE:

with integrated high precision sensor (Full scale range: + – 6.5 KPa)

It can be programmed to operate as simple sensor and report the value of the measurements on the display, via

ModBus RTU or as analog output signal, or also with the PID controller function that will provide the signal to the

power actuator (fan, solenoid valve, etc.).

Via ModBus RTU all the information are always available, while the analogue output must be programmed according

to the measurement to be supplied in output (temperature_1, temperature_2, temperature_3, pressure, PID output).

Thanks to 4 buttons EM45-SN can be manually programmed. A user-friendly menu is available on the integrated

OLED display or with a host computer/smartphone via ModBus protocol.
