BMX CPS ppppp power supply modules provide the power supply for each
BMX XBP pp00 Modicon M340 rack and the modules installed on it.
The Modicon M340 power supply module offer comprises:
Three power supply modules for DC line supplies:
24 V c isolated power supply module, BMX CPS 2010
24...48 V c isolated power supply module, BMX CPS 3020
125 V c power supply module, BMX CPS 3540T (extended operating
temperature -25° to +70°C)
Two power supply modules for AC line supplies:
100...240 V a, 20 W power supply module, BMX CPS 2000
100...240 V a, 36 W power supply module, BMX CPS 3500
Description
The power supply module is selected according to:
The electrical line supply: 24 V c, 48 V c, 125 V125 V c or 100...240 V or 100...240 V a
The required power (see the power consumption table on page 7/16)
(1)
BMX CPS ppppp power supply modules have the following on the front panel:
1 A display block comprising:
OK LED (green), lit if rack voltages are present and correct
24 V LED (green), lit when the sensor voltage is present (BMX CPS 2000/3500/
3540T AC power supply modules only)
2 A pencil-point RESET pushbutton for a cold restart of the application
3 A 2-way connector that can take a removable terminal block (cage clamp
or
spring-type)
for connecting the alarm relay
4 A 5-way connector that can take a removable terminal block (cage clamp
or
spring-type)
for connecting the following:
c or a line supply
Protective earth
Dedicated 24 V c power supply for the input sensors (for BMX CPS 2000/3500//
3540T AC power supply modules only) AC power supply modules only)
Included with each power supply module:
Set of two cage clamp removable terminal blocks (5-way and 2-way)
BMX XTS CPS10
To be ordered separately (if necessary):
Set of two spring-type removable terminal blocks (5-way and 2-way)
BMX XTS CPS20
Functions
Alarm relay
The alarm relay incorporated in each power supply module has a volt-free contact
accessible on the front panel, on the 2-way connector.
The operating principle is as follows:
In normal operation, with the PLC in RUN, the alarm relay is energized and its
contact is closed (state 1).
The relay de-energizes and its associated contact opens (state 0) whenever the
application stops, even partially, due to any of the following:
Occurrence of a blocking fault
Incorrect rack output voltages
Loss of supply voltage
