A microcomputer-based device supports many connections, input devices and operating modes and adds diagnostic and status monitoring for IoT data.

Safety relays are crucial for monitoring safety-related inputs and for protecting both machines and operators by enabling equipment via outputs only when normal and safe conditions are confirmed. Usable with Safety Category 1, 3 and 4 applications, Model HR6S is designed to meet ISO 13849 requirements. The line of safety relay modules includes one model for low risk applications and six models suitable high risk processes requiring redundancy. Up to eight start modes are dial-selectable, including options for manual and automatic start. Certain models have adjustable off-delays, and all use a compact DIN-mountable form factor. An expansion module is available to increase the number of safety outputs.
