is not powered, the loads remain still connected to the auxiliary source and to the plant
battery.
If the outputs are not used for the circuit breakers commands, they can be associated to
different functions (see par. 5.5.3).
The device operates 8 digital outputs, entirely programmable: 4 are available by means
connector JE, dedicated for this function, 4 are in connector JT, using 4 of the 8 available
terminals.
When activated, they bring themselves to the positive supply voltage on the JD supply
terminal.
The rated capacity of each output is 500mA.
REMARK: the total supplied current from the 8 outputs can’t be greater than 2A.
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 JD 2-+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 HS315 under any condition of
use.
The digital outputs of the controller can be extended by adding two DITEL 16 IN modules
(connected to HS315 by Can Bus), each of them in charge of up to two DITEL 8 OUT relay
modules, up to a total of 32 additional outputs.
Each output is completely configurable individually.
By default, all the outputs are activated when their function requires it (for example the fuel
pump output starts operating when the pump must be activated).
Using the BoradPrg3,
you can reverse the activation by simply ticking the “reverse polarity”
box on top of the configuration page of every single output.
By operating directly on the controller you can reverse anyway the logic of the outputs (still
individually for each output) including by means of the parameters P.3000 for the outputs on
the controller (a total of 12 bits), P.3200 (16 bits) for the two DITEL 8 OUT additional modules
connected to the first DITEL 16 IN controller and P.3250 (16 bits) for the two DITEL 8 OUT
additional modules connected to the second DITEL 16 IN:
