Guard I/O Modules Overview

Control and monitor your safety devices with Guard I/O. When used with Rockwell Automation safety controllers, Guard I/O communicates on EtherNet/IP or DeviceNet using CIP Safety protocol. As an effective technology, Guard I/O detects failures at the I/O and field device level, while helping enhance operator protection.

CompactBlock Guard I/O modules are available in IP20 (in-cabinet) form factor. ArmorBlock Guard I/O modules are IP64, IP65, or IP67 (on-machine) form factor (as marked on the product label). POINT Guard I/O provides maximum I/O density in minimal panel space.

Guard I/O modules offer the following advantages when implementing a safety control system:
