Rockwell Automation 1792D-12BVT4D ArmorBlock MaXum 12 Input/4 Output Module Series B - Manual (Page 6)

6 ArmorBlock MaXum 12 Input/ 4 Output Module Series B
Publication 1792D-IN004B-EN-P - August 2000
Use the micro caps to cover and seal unused ports. Pinout diagrams
for the connectors are shown next.
Molded I/O cables with LEDs embedded in the connector are
incompatible with MaXum universal sink/source inputs. Please refer
to publication 889-5.0 for Rockwell Automation cables and cord sets
offerings.
IMPORTANT
If the devices (sensors) connected to the input
connections require Class 2 power to operate, the
DeviceNet connections of this equipment must be
powered by a Class 2 source.
ATTENTION
!
• Make sure all connectors and caps are
securely tightened to properly seal the
connections against leaks and maintain
IP67 requirements.
• For maximum noise immunity, input and
output cable return wires must be properly
terminated. When inputs and outputs are
connected in loopback, return wires should
be connected together.
• I/O cable length should be less than 30
meters.
