IDEC Corporation has released the HR5S safety relay module. The module is said to be the first on the market designed specifically to meet ISO 13849 Category 2 requirements. Since the safety relay modules specifically comply with Category 2 requirements, they increase designer flexibility when the required performance level (PLr) risk assessment identifies conditions to be PLc or below, the company says.
The IDEC 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 45 mm of installation width, the HR5S is 22.5 mm wide and can be mounted on DIN rails or a backpanel surface.
Push-in terminals are used for ease of 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 safety relay modules comply with many standards including EN ISO 13849-1:2015 and UL 508.
