Samba™ PLC+ HMI
Unitronics 9
RTD

PT100 (Sensor 0): use Input 9 and 10, related to CM signal.

PT100 (Sensor 1): use Input 7 and 8, related to CM signal.

4 wire PT100 can be used by leaving one of the sensor leads unconnected.
Analog Outputs Transistor Outputs (pnp)

The 0V signals of the transistor and the analog outputs must be conne
cted to the controller’s 0V.

Outputs 0 to 4 can be used as PWM outputs.
Power Supply
The controller requires an external 24VDC power supply.

The power supply must include double insulation. Outputs must be rated as
SELV/PELV/Class2/Limited Power.

Use separate wires to connect the functional
earth line (pin 3) and the 0V line (pin 2) to the
system earth ground.

Install an external circuit breaker. Guard
against short-circuiting in external wiring.

Double-check all wiring before turning
on the power supply.
 Do not connect either the ‘Neutral’ or ‘Line’
signal of the 110/220VAC to device’s 0V pin

In the event of voltage fluctuations or non-
conformity to voltage power supply
specifications, connect the device to
a regulated power supply.
