PROTECT SRB301 Series Safety Relays

Introducing the PROTECT SRB301 series of Safety Relays. These are a perfect fit for signal evaluation, specifically the outputs of safety magnetic switches. They function well with such safety applications like Light beams/curtains, Safety mats or Safety switches/interlocks.



Features and benefits

• Snap on DIN rail mounting as standard with this product allowing easy additions & removals, allowing you the flexibility and portability you require.
• 240 of lightweight, durable plastic (glass fibre) reinforced thermoplastic. The structure is also ventilated meaning it dissipates heat quicker allowing the device to remain cool.
• The material of the contact is a standard AgSn0. It has a positive action and is also self-cleaning.
• Automatic or manual start button input allowing you further control over your device (optional monitored).
• A feedback circuit as standard with this product allows the unit to detect any welding of the contact point, which is particularly useful in keeping the relay running instead of shutting down upon contact.

Advantages of the SRB301ST

• A 20 year mission time for this device, giving you the confidence in the quality of the build
• Compact in design allowing you more mounting on your DIN rail or equivalent
• Low power consumption compared to other units on the market
