When connecting the I/O channels, do not exceed the values indicated in the technical data
given below:
·
INPUT
-
Input voltage for channel activation: 14 to 35 Vdc;
-
Input voltage for channel deactivation: 0 to 15 Vdc;
-
Input current with channel activated: 2 to 15 mA;
-
Maximum input current with channel not activated: 0.5 mA.
·
OUTPUT
-
Operating voltage: 4.5 to 36 Vdc;
-
Maximum output current with channel not activated: 0.25 mA;
-
Maximum voltage drop with channel active: 1.8 Vdc;
-
Maximum output current with all channels active: 0.5A@ta=25°C;
-
Maximum output current with all channels active: 0.5A@ta=45°C.
The IOM module can be powered using the 24 Vdc voltage generated by the control unit or by an external
power supply connected to connector X30. THE MODULE IS USUALLY POWERED BY THE 24 VDC GEN
-
ERATED BY THE CONTROLLER.
If the user decides to power the IOM module with an external power supply, jumpers JP 200 and JP 201 on
the SDB3 module for IOM slot 4 and/or SDB3-2 for IOM slot 6 must be set as shown in the following figures.
The I/O’s may be powered in sets of eight. These groups may be powered with a 24 Vdc
power supply inside or outside the control unit. Usually, the entire module (8+8 outputs and
8+8 inputs) is powered using one or the other type of power supply. However, it is possible
to power the IOM module with two power supplies at the same time dividing the I/O’s as fol-
lows:
· INTERNAL POWER SUPPLY: inputs 1-8 / outputs 1-8;
· EXTERNAL POWER SUPPLY: inputs 9-16 / outputs 9-16;
or vice versa.
In the PDL2 programming language, the I/O’s of the IOM module are identified as follows:
IOM SLOT 4
·
input 1 to 16 º $din[1] to $din[16];
·
output 1 to 16 º &dout[17] to $dout[32].
·
Output 16 $dout[32] is not available.
IOM SLOT 6 (ONLY FOR C3G Plus VERSIONS DDMP - DDHP)
·
input 1 to 16 º $din[33] to $din[48];
·
output 1 to 16 º $dout[49] to $dout[64].
Output 16 $dout[64] is not available.
