Brad HarshIO modules have been designed for applications that meet safety levels such as SIL 3 (Safety Integrity Level 3) and Cat4/Ple and where communication via EtherNet/IP is required to exchange standard safety and control data and diagnostic information over a simple Ethernet network.
The compact modules consist of 12 safe inputs and 4 safe outputs, supporting the connection of single- and dual-channel safety devices, making them ideal for automotive applications operating robots in cells. The digital inputs and outputs can connect to both standard and safety sensors and utilize test pulses for connected standard outputs to perform diagnostics on panel lights, buzzers, and standard actuators. An integrated, overmolded memory key, available internally or via an M8 connector, saves the configuration and allows for module replacement in one minute without special tools or a complete re-commissioning process.
Advanced features, such as an integrated 2-port Ethernet switch with Device Level Ring (DLR) topology, diagnostic LEDs, and a flexible IP address configuration method, simplify setup and operation. The integrated 2-port DLR switch can be daisy-chained, allowing the user to wire the entire application without additional switches, thus reducing costs. Molex M12 Ultra-Lock™ connectors, featuring a push-to-lock mechanism, save machine space by allowing sensors and actuators to be connected directly to the input/output module, establishing an environmentally sealed Ethernet connection with an IP67 rating. HarshIO modules are compact, measuring only 240 mm x 62 mm x 46 mm (9.44” x 2.44” x 1.77”).
The units are Rockwell Automation Ready and compatible with Rockwell GuardLogix™ controllers. Commissioning is easy thanks to Molex's SNCT software and Rockwell Automation's Studio 5000 Logix Designer™ application. (RA Note: Logix Designer is the new brand name assigned to RSLogix™ 5000 software.) Certifications and regulatory approvals for the modules include: TÜV and ODVA, compliance with EN 61508 SIL3, Cat4/Ple according to ISO 13849-1, CE, RoHS, REACH, UL/cUL, and Korea and China CC (CCC).
