Please find the complete data in the user's documentation. Our General Terms of Use for Downloads are valid (http://phoenixcontact.com/download) One or two-channel contact extension for OSSD signals (e.g., light grid), 3 N/O contacts, 1 N/C contact, up to Cat. 4 PL e in accordance with EN ISO 13849, SIL 3 in accordance with EN 62061, pluggable Push-in terminal block, width: 22.5 mm The figure shows a version with a screw connection ## Product Description The contact extension device is specifically designed for use in conjunction with electrosensitive protective equipment such as light grids. These systems generally have clocked OSSD signals which enable cross circuits in the cabling to be detected. The relay is resistant to the test pulses generated by the electrosensitive protective equipment receiver. Applications up to PL e or SIL 3 can therefore be implemented without the need for additional traceability to the device on the EDM circuit. ## Your advantages - Time saving push-in connection, tools not required - Potentials can be easily looped through – ideal for BUS applications - Intuitive use through colour coded actuation lever - Can be combined with the MSTB 2,5 range Quick and convenient testing using integrated test option ST EN Iso 1aa4g|| [EC 62061 Key Commercial Data Packing unit ~~ee~~ 1 pc GTIN 4"046356'751704 ~~eee (UMN!
