The Allen-Bradley 1791DS-IB8XOBV4 is a Guard I/O DeviceNet Safety Module. The I/O guard module applies the CIP security protocol extension to the DeviceNet Network. It also provides various features for security systems. This module has solid state outputs. The enclosure type of this module meets the IP64/65/67 standards. The 1791DS-IB8XOBV4 module has 8 safety inputs and 8 safety outputs. This module meets the requirements of Safety Integrity Level 3 (SIL 3) as defined in the IEC 61508, Electronic, Electronic, and Programmable Electronic Security Functional Safety requirements, and requirements for a Category 4 4 EN standard 4, Safety machine - related to the safety of the control system.

The 1791DS-IB8XOBV4 module has a self-diagnostic function. It performs when the power of this module is first turned on and periodically during operation. If a fatal internal module error occurs, the red module status indicator lights up, and the data security and output and data input to the network are turned off. This module conforms to EMC standards. This module comes with safety features like emergency stop buttons, gate switches, and safety light curtains. The timing of the logical difference between the 2 channels can be monitored by using inaccurate timing. Do not disassemble, repair, or modify the module. This may result in a loss of safety functions. Use only those components or devices that conform to the relevant safety standards and which conform to the required safety and security categories. The 1791DS-IB8XOBV4 has an operating temperature of 13-158 ° F. The nonoperating temperature is from -40-185 °F.
