Guard I/O
Improve Productivity; Simplify Control System Design, While Enhancing Operator Protection
Guard I/O™ provides all the advantages of traditional distributed I/O for safety systems. Distributed safety I/O reduces wiring costs and startup time for machines and cells, as compared to in-chassis I/O.
You can use Guard I/O with any safety controller that communicates on DeviceNet or EtherNet/IP networks using CIP Safety, for the control and monitoring of safety circuits. With CIP Safety you can easily integrate safety and standard control systems by using safety and standard messages on the same wire.
Guard I/O detects circuit failures at each I/O point while providing detailed diagnostics directly to the controller. The distributed I/O intelligence enables a safety system's input and output circuits to be rated up to SIL 3 and Category 4, while optimizing installation costs.
Several Guard I/O blocks are available with a variety of features.
1791DS CompactBlock Guard I/O
The 1791DS CompactBlock Guard I/O (in cabinet) family consists of 24V dc digital I/O modules that communicate on DeviceNet networks.
1791ES CompactBlock Guard I/O
The 1791ES CompactBlock Guard I/O family consists of 24V dc digital I/O modules that communicate on EtherNet/IP networks.
1732DS ArmorBlock® Guard I/O
A remote I/O for controlling and monitoring safety devices on DeviceNet using the CIP Safety protocol.
