Rockwell Automation has introduced safety I/O modules equipped with EtherNet/IP connectivity, the CompactBlock guard I/O on EtherNet/IP series.
The 1791ES-IB16 and the 1791ES-IB8XOBV4 modules allow users to streamline network architectures by employing industry-standard EtherNet/IP protocol for all safety, standard and motion control communications.
Rated to Safety Integrity Level 3 (SIL3)/Category 4, the new CompactBlock guard I/O on EtherNet/IP series uses Common Industrial Protocol (CIP) Safety, making it compatible with standard Ethernet infrastructure devices, including wired and wireless technologies.
Importantly, the new CompactBlock guard I/O modules enable users to control and monitor devices using a single data communications network for factory-floor standard and safety control, as well as enterprise-level business management systems.
The 1791ES-IB16 is equipped with 16 inputs, while the 1791ES-IB8XOBV4 comes with eight inputs and four dual-channel bipolar high-current outputs. The new Ethernet/IP-ready modules can be configured to accommodate both low- and high-current applications (up to 2A), providing high levels of operational flexibility.
The unit’s high-current solid-state outputs eliminate the need for the interposing relays normally required for such high-current applications. This saves panel space and reduces installation and maintenance costs, while providing improved reliability.
For low-current applications (up to 1A), users can achieve SIL3/Category 4 status using a single bipolar output. This doubles the capacity of the I/O module traditionally; SIL3/Category 4 status requires the use of two outputs per application.
With multi-output capabilities, the versatile CompactBlock guard I/O on EtherNet/IP series is designed for a variety of industrial safety applications, including robotics, point-of-operation, guard-monitoring and remote-control.
The new CompactBlock guard I/O on EtherNet/IP modules are equipped with up to sixteen integrated pulse testing/standard outputs, which can be configured to detect wiring/device faults, and are provided with comprehensive LED diagnostics.
The Ethernet-ready modules also feature removable keyed terminal blocks and remove/install under power (RIUP) capabilities, which simplify installation and streamline system maintenance and module changeovers.
