PH6501-4A2B

Applied in Extension Module

    Overview

    PH6501-4A2B is a safety relay output expansion module that receives on-site safety switch signals and expands into 4 normally open (NO) safety output contacts and 2 normally closed (NC) auxiliary output contacts. The 2 auxiliary contacts can be used for output status indication and fault feedback, respectively.

    Wiring diagram

    (1) The instrument wiring adopts Pluggable connecting terminal ;
    (2) The soft copper cross-sectional area of the input side wire must be greater than 0.5mm2, and the output side must be greater than 1mm2;
    (3) The exposed length of the wire is about 8mm, which is locked by M3 screws;
    (4) The output contacts must provide enough fuse protection connections;
    (5) Copper conductor must withstand an ambient temperature of at least 75 ℃; 
    (6) Terminal screws can cause misoperation, heating, etc. Therefore, please tighten it according to the specified torque. Terminal screw tightening torque 0.5Nm.

    Installation

    Safety relays should be installed in control cabinets with at least IP54 protection level.Meanwhile, the installation and use should comply with the relevant provisions of GB 5226.1-2019 "Mechanical and Electrical Safety - Mechanical and Electrical Equipment - Part 1: General Technical Conditions".
    The PH6501-4A2B series safety relays are all installed with DIN35mm guide rails. Installation steps are as follows
    (1) Clamp the upper end of the instrument onto the guide rail;  
    (2) Push the lower end of the instrument into the guide rail.
