This ABR1 input interface module is part of the range Zelio interfaces ABR/ABS. It is supplied in the form of compact module, 17.5 mm wide. It is designed for switching input signals to the processor and is characterized by its high degree of contact reliability less than 1 fault per 100 million operating cycles at 17 V dc, 5 mA. The switching level is sufficiently high to ensure that the interfaces can directly control most contactors and indicator lamps. It is based on contactor technology and is notable for its excellent adaptation to industrial environments, ensured by the fact that it conforms to the most recent IEC 947-5-1 standards. |
