1791DS CompactBlock Guard I/O
CompactBlock™ Guard I/O™

|
Description
CompactBlock 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. Guard I/O detects circuit failures at each I/O point while providing detailed diagnostics directly to the controller. With CIP Safety you can easily integrate safety and standard control systems by using safety and standard messages on the same wire.
Several Guard I/O blocks are available with a variety of features:
- The 1791DS CompactBlock Guard I/O family consists of 24V dc digital I/O modules that communicate on DeviceNet networks.
- The 1791ES CompactBlock Guard I/O family consists of 24V dc digital I/O modules that communicate on EtherNet/IP networks.
Benefits
- TÜV certified as a system with GuardLogix, GuardPLC 1600 and 1800, and SmartGuard 600 controllers
- Supports both standard and safety control
- I/O point-level and other detailed fault diagnostics are available to the PLC or HMI, with the self testing inputs and outputs
- EDS (RSNetWorx for DeviceNet) or RSLogix 5000 profile configuration
- TÜV and UL certified for functional safety up to SIL 3 and Category 4
- Supports single and dual channel devices on inputs and outputs
- Additional standard solid-state outputs that can be configured as pulse test sources, outputs for standard PLC control, 24V dc sources, or for muting lamp control and monitoring
- DIN rail mounting for easy installation
- Compatible with Guardmaster and similar safety devices
