16-input AS-Interface slave for control-cabinet mounting
The Siemens 3RG9002-0DE00 is an AS-Interface F90 module providing 16 digital inputs arranged in four groups of four, each with a dedicated group signal for the voltage supply of the inputs. The input groups are activated individually by the control system setting the respective group signal, and the switching states of the assigned inputs are then read in. An external auxiliary supply of 20 to 30 V DC is required for the output circuits, complying with VDE 0106 (PELV), protection class III.
