Ethernet safety I/O modules

Rockwell Automation has introduced 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 protocols for all safety, standard and motion control communications.
Rated to Safety Integrity Level 3 (SIL3)/Category 4, the series uses Common Industrial Protocol (CIP) safety, making it compatible with standard ethernet infrastructure devices, including wired and wireless technologies. The 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. These Ethernet/IP-ready modules can be configured to accommodate both low- and high-current applications (up to 2 A), 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.
For low-current applications (up to 1 A), users can achieve SIL3/Category 4 status using a single bipolar output. This effectively 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 series is designed for a variety of industrial safety applications, including robotics, point-of-operation, guard-monitoring and remote-control.
The modules are equipped with up to 16 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.
