1.Basic introduction 

SR series safety relays is a new type of safety relays,beautiful appearance,structure compact,and reach to the best safety by the smallest cost.SR series safety relays is a kind of products designed according to the European design standards,certified by European safety standard CE and has achieved national CCC safety certification,correspond to 2006/42/EC,2004/108/EC,EN ISO 13849-1,EN 60947-4-1,EN 60947-5-1 and so on standards. Safety relays are widely used in safety light curtain,safety door,a sudden stop switch and so on safety and sudden loop, can set double channel operation to make sure security, to prevent accident and stop.

2. SR series's specification

SR has several specification.They are SR4P2A1B22,SR4P2A1B24,SR4P2A1B24P,SR4P2A1B24N,SR4P3A1B24,SR4P2A1B24S,

4. Detail introduction

SR series safety relay controls one set light curtain, is mounted inside the electrical cabinet.

SR series safety relay is directly inserted into 35mm rails of the inside electrical cabinet of press or equipment.

If periphery has strong electromagnetism noise source(for example transducer,high frequency machine and so on),the controller should be far away from them to avoid the interference.

(1)Output various form,widely  application.

(2)The input contacts's short citcuit fault can be detected,safety performance is good.

(3)You can choose manual reset or automatic reset,operation convenience.

(4)It has self monitoring redundancy circuit ,safety performance is good.

(5)It has status indicators,facilitate fault ispection.

(6)It has removable terminals,facilitate installation and connection.
