PWR-240B
DC OK Monitoring
The DC voltage terminal block provides two wiring terminals (13-14), which monitor the
status of the switching power supply (DC OK feature). When the power supply module
runs correctly, lines 13 and 14 form a normally closed contact. If the power module
experiences problems (i.e. output overload causing output voltage to be reduced by less
than 90% of nominal) these lines open. Lines 13 and 14 are decoupled from the power
output lines and can be connected to a free digital input to signal this alarm condition.
DC Direct Output
The 24 volt DC Output terminals are direct. Connect the output devices according to
your application requirements.
LASER BARCODE SCANNERS
Supply Capacity When Wiring Directly to AS-I Compatible Scanners
For direct wiring, power distribution is performed simultaneously for all the scanners.
However all the scanner motors start up slowly so that there is no significant peak cur -
rent draw. See the specific scanner manual for consumption data.
The maximum number of same type scanners to be supplied for direct wiring the PWR-
240B is shown in the table below and depends on the wiring topology:
The following products are also AS-I compatible: DS5100, DM3610, SC5000. In case of
networks using a mix of products, you must calculate the total power consumption so as
not to exceed the limits for the specific topology used. See the specific product refer -
ence manual in the Technical Features chapter for consumption data.
The power supply unit is connected directly to the scanners via AS-I cabling.
