These XPSBCE modules incorporate 2 N/O safety outputs and a relay output for signalling to the PLC.Features and Benefits:-Have 3 visible LED’s to provide information on the monitoring circuit statusTypical Applications:-For electrical monitoring of two-hand control stationsNotes:-Meet the requirements of Performance Level PL e/Category 4 conforming to standard EN/ISO 13849-1 and the European standard EN 574/ISO 13851 for two-hand control systemsWarnings:-Control stations must be designed and installed such that they cannot be activated involuntarily or easily rendered inoperative-Depending on the application, the requirements of type C standards specific to the machinery involved must be met (additional personal protection methods may have to be considered)-To initiate a dangerous movement, both operators (two-hand control push buttons) must be activated within 0.5 s (synchronous activation). If one of the two push buttons is released during a dangerous operation, the control sequence is cancelled. Resumption of the dangerous operation is possible only if both push buttons are returned to their initial position and reactivated within the required time interval-The safety distance between the control units and the hazardous zone must be sufficient to ensure that when only one operator is released, the hazardous zone cannot be reached before the dangerous movement has been completed or stopped
