3.1.2. Inputs and actuators
The instrument is fitted with 7 actuators used to power the sensors connected to the terminal board,
(4 actuators for 8 analogue inputs in
differential mode and 16 in single-ended mode(§3.1.3), 2
actuators for 4 digital inputs, 1 actuator for other functions); the actuators can also be used by the
actuation programmable logics, than can produce alarms according to the values acquired by the
sensors . The voltage available on these terminals depends on the kind of power supply received by
the instrument.
Use the program
3DOM (see SWUM_00339 available on LSI LASTEM product DVD – MW6501)
to configure the operation to switch on the sensors by means of the switching powers. In order to
choose the actuation time is advisable to consider both the energetic saving and the time the sensor
needs to initialize.
The association between input and switching power is fixed, as shown in the table below. The
number of the terminal is indicated in italics; we understand, for example, that inputs 1 and 2 both
make use of the first actuator; therefore it cannot be used for the other inputs. In case of sensors that
generate two signals (like the thermo-hygrometric sensor), it’s suitable to select both inputs that use
the same actuator.
