German machine turning experts turn to Murrelektronik’s Exact12 passive distribution boxes
When German turning machine experts, Schuster Maschinenbau GmbH needed a passive distribution box solution, to engineer installations with overall pluggable connection from the control cabinet into the field, they naturally turned to Murrelektronik's Exact12 series.
Exact12 passive distribution boxes
Murrelektronik's unique, new distributor concept with passive distribution boxes from the Exact12 series allow Schuster Maschinenbau GmbH to engineer installations in their machines with overall pluggable connection from the control cabinet into the field.
By implementing the well-engineered distribution concept based on Exact12, Schuster can completely eliminate terminal boxes that take a lot of space in the machine and require time-consuming, error-prone and expensive installation.
Herbert Assner is the manager of the electrical department at Schuster Maschinenbau GmbH. One of his tasks is installing and connecting the I/O points of the machines and systems in a very simple, reliable and cost-effective manner into the cabinet and connecting them to the control.
"In the cabinet, they are transferred with a transfer module with spring clamp terminals," says Assner.
"This goes very fast, because it's no longer necessary to connect up to 23 terminal points to terminal blocks by hand," he adds.
And with pre-wired terminals, Schuster can be certain that their components are already 100% tested. "This way, one possible error source is already eliminated, when the machine is commissioned," Assner explains.
A service adapter also offers an additional option to visually check all I/O signals. If all connections are error-free, the test LED on this control component light up and directly show the signal states.
This installation concept creates a clear separation between control cabinet and machine peripherals. With this system of transfer adapters in the cabinet we also have a simple separation for transport that facilitates on-site commissioning.
“The additional connectors that otherwise are used to separate the machine are also no longer required. With this distribution system, we have found the optimum solution."
