IDEC HR5S module designed to comply with updated ISO 13849 Safety Category 2 requirements.

IDEC Corporation released its HR5S safety relay module designed to meet ISO 13849 Category 2 requirements. The safety relays are available in three configurations for a range of applications. The Simple type can be used for applications up to PLc, while Standard and Off-Delay types work for designs up to PLd and add failure detection features. While most Category 3 and higher relays consume 45mm of installation width, the HR5S is only 22.5mm wide and can be mounted on DIN rails or a backpanel surface. Push-in terminals are used for installation and vibration resistance, accepting solid wires up to 16 AWG or stranded wires up to 18 AWG with ferrules. Inputs are rated for 24V DC, and outputs are rated up to 250V AC 3A. The HR5S safety relay modules comply with many standards including EN ISO 13849-1:2015 and UL 508.
