CompactBlock Guard Safety I/O Modules

Our Bulletin 1791DS and 1791ES CompactBlock™ Guard I/O™ modules provide the advantages of distributed I/O for safety systems. These modules work with safety controllers that communicate on DeviceNet™ or EtherNet/IP™ networks using CIP™ Safety. CompactBlock Guard Safety I/O is optimized to work with GuardLogix®, and SmartGuard™ controllers.
