5.5.1
T.09 D+ Input used as analogue input
If the engine does not require the energizing connection, you can configure
T.09
as auxiliary
powered ANALOGUE input, with measuring range 0-32VDC with respect to the power minus
of the controller (GND), associating to it one of the functions available by means of the P.4001
parameter.
It can be used to acquire many measures, see par. 5.7.2 and the chart included.
5.5.2
T.09 D+ Input used as analogue input
It is possible to configure the input
T.09
as a further digital input, connected to a signal source
between 0 and 32VDC. It is considered active when the voltage measured is higher than
4.0VDC; it is considered not active when the voltage measured is lower than 3.5VDC.
Therefore, it cannot be activated like the other inputs, which is by connecting it to the ground.
If it is configured as digital input, its status is displayed on page S.05 (0=input not active,
1=input active).
5.6
The device manages four digital outputs, entirely programmable. When activated, they bring
themselves to the positive supply voltage on the
T.02.
supply terminal.
The rated capacity of each output is 500mA; the total power is, therefore, of 2A.
In full speed,
do never overpass these values
.
The outputs are independent and protected individually from overloads, short circuits, polarity
reversal and overheating. The overload protection cuts in to limit the current spikes to an
instantaneous value of 4A, to allow the activation of loads that require a transient inrush current
greater than the rated. If this condition persists, after 150us the thermal protection cuts in
progressively, until the output is turned off.
With inductive loads (power relays, electromagnetic actuators), although some are already
present inside, it is advisable to use diodes for damping opening over voltages.
All the current delivered by the outputs must be made available through the JE
T2-+BATT;
make sure that any safety fuse on the supply plus has a capacity and response time
suitable to power and protect both the outputs and the controller under any condition
of use.
The outputs functions configured by default are the following:
