Supply modules

PN750-601, 602, 609, 610, 611, 612, 613, 615

Technical Description

The supply module provides I/O module power through the power jumper contacts. Maximum current supply to all connected modules is 10 A. Maximum current supply to the modules with fuse holder is 6.3 A. Should higher currents be necessary, intermediate supply modules may be added in the assembly.

The modules 750-601, 609, 615, 610 and 611 are additionally equipped with a fuse holder. The change of the fuse is very easy by drawing out the fuse holder and changing the fuse. A blown fuse is indicated by a LED.

The modules 750-610 and 611 send information about the status of the supply module to the fieldbus coupler through two input bits.

Bit1	Bit2	Description
0	0	voltage < 15 V DC
1	0	fuse blown
0	1	fuse o.k., voltage o.k.

Using the supply modules you have to look for the allowed voltage. The following table shows the voltage for the supply modules.

The supply module 750-613 supplies the field side and te internal databus system voltage. The internal system voltage can supply 2 A max. If the sum of the internal current consumption exceeds 2 A, an additional supply module must be added.
