Protection l 24 V system voltage is protected by a definite plug−in direction in the housing.
l 5 V bus voltage is protected by a definite plug−in direction in the housing.
l Sensor supply is protected against short circuit, overcurrent and negative feed
l Current and voltage inputs (optional) are protected against voltages up to 32 V
l Input protection via high resistance voltage dividers
l Protection of the sensor feed via series diodes and active current limitation
l ESD protection via Transil diodes at PE
l Output protection via passive current limitation
l Series and parallel diodes, short−circuit proof
l ESD protection via Transil diodes at PE
