MINIATURE DIN-RAIL INTERFACE UNITS October 1st 2004 Tapeswitch has introduced a miniature DIN-rail interface unit for safety mats, sensing edges and other ribbon-switch sensors.
The PSSZ-2 has category 3 fail-safe monitoring, yet is similar in size to a DINrail terminal.
The interface units monitor the safety sensor by using a single, two-wire lead that reduces the complexity of the installation and can prove the most practical option.
The company comments that in some four-wire applications, it would be impractical or impossible to have leads fitted at each end of the sensor.
The PSSZ-2 has solidstate, volt-free outputs that means it is compatible with virtually any interface, including the input modules or bus systems such as AS-i. It also has an LED function, illuminating red or green, prominently displaying the sensor’s status. More articles from Tapeswitch Ltd: |
