IDEC HR6S safety relay module

The IDEC HR6S safety relay module is a microcomputer-based device that supports a wide variety of connections, input devices and operating modes, as well as adding diagnostic and status monitoring important for the growing number of manufacturing sites relying on 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.

The adaptable safety relay module is designed to meet ISO 13849 requirements, with one model for low-risk Safety Category 1 applications and six models suitable high-risk Safety Category 3 and 4 processes requiring redundancy. Up to eight different 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 expand the number of safety outputs.

Depending on the model, up to seven types of input devices are dial-selectable, including emergency stop switches, two-handed switches, pressure-sensitive devices and other types of interlock switches. Terminations are arranged intuitively, with terminal blocks available as push-in or screw type.

Maintainability and convenience are aided by multiple LEDs with steady or flashing coloured lights indicating various conditions such as power, error and operating state. Users can quickly check the status onsite, identifying any issues so immediate action can be taken.
