Visualizes status of relay output OUT A1 on CN3. When the LED
is lit the output is connected to common terminal COMMON A.
Visualizes status of relay output OUT A2 on CN3. When the LED
is lit the output is connected to common terminal COMMON A.
Visualizes status of relay output OUT B1 on CN3. When the LED
is lit the output is connected to common terminal COMMON B.
Visualizes status of relay output OUT B2 on CN3. When the LED
is lit the output is connected to common terminal COMMON B.
Visualizes status of relay output OUT C1 on CN3. When the LED
is lit the output is connected to common terminal COMMON C.
Visualizes status of relay output OUT C2 on CN3. When the LED
is lit the output is connected to common terminal COMMON C.
Visualizes status of relay output OUT D1 on CN4. When the LED
is lit the output is connected to common terminal COMMON D.
Visualizes status of relay output OUT D2 on CN4. When the LED
is lit the output is connected to common terminal COMMON D.
Visualize status of optocoupled inputs 1÷8 on CN1. When one LED
is lit there is a current flowing between input INP n-1 and common
terminal COM 1.
Visualize status of optocoupled inputs 1÷8 on CN2. When one LED
is lit there is a current flowing between input INP n-2 and common
terminal COM 2.
If lit, then the combination of jumpers J1 and J2 is set to make the
optocoupled inputs on CN1 and CN2 type NPN.
If lit, then the combination of jumpers J1 and J2 is set to make the
optocoupled inputs on CN1 and CN2 type PNP.
LD27
Yellow If lit, indicates that switching power supply is generating +5 Vdc.
LD28
Yellow
Visualizes status of signal MM PIN 11 connected to pin 4 of CN7,
which is also optional Real Time Clock interrupt signal.
FIGURE 27: LEDS TABLE
The main function of LEDs is to inform the user about card status, with a simple visual indication
and in addition to this, LEDs make easier the debug and test operations of the complete system. To
recognize the LED location on the card, please refer to figure 25.
All the LEDs described in figure 27 are visible from the breaks on the plastic container dedicated to
the connectors, to allow inspection also when the board is closed and installed in the electric panel.
In addition, LEDs that display buffered I/O are physically located near the corresponding pins to easy
cabling verification and all other evental working tests.
