GuardLogix
L7s For customers who are looking to expand their ControlLogix systems with Integrated Safety. Rockwell Automation is extending their GuardLogix product platform with the new 1756-L72s and 1756-L73s processors. These processors along with a new 1756-L7SP safety partner will allow customers to be able to control more equipment and reduce scan time over previous L6s controllers. These processors are also designed for SIL 3, PLe safety applications.
The 1756-L72s is designed to handle 4megabytes of standard memory, and the 1756-L73s is designed to handle 8 megabytes of standard memory. Each controller also has additional memory for the safety program. The number of connections in each controller has been expanded from 250 to 500. This will allow you to control significantly more devices than the previous L6s controllers. The new L7s controllers from Rockwell Automation will be available with version 20 of RSLogix 5000 and should be available in early January.
SensaGuard
Integrated Latch
For machine builders and manufacturers using lightweight guard doors, the newest-generation PLe, SIL3, Cat 4, Safety Switch - the 440N-Z SensaGuard Non-Contact Switch with a magnetic Integrated Latch - is the first in the world to combine a non-contact interlock switch and door latch into one integrated solution. It replaces separately mounting an interlock switch and door catch, which simplifies installation and increases reliability. The magnetic integrated latch is adjustable for use with a variety of lightweight guard doors requiring different holding force (from 15N to 45N), including framed or frameless, vertically or horizontally hinged, single or double, gull wing or tailgate and sliding guard doors. For example, gull wing doors slant downward, and gravity helps keep them from opening on their own from machine or shock vibration. As a result, gull wing doors need low holding force to remain closed during machine operation. Tailgate or drop-down doors, however, need a higher holding force because gravity works against the latch. Users can adjust the latch according to unique holding force requirements to keep doors closed during machine operation.
