SAP5S/SAP51 is a new generation CMOS integrated circuit for AS-I networks. The low-level field bus AS-I (Actuator Sensor Interface) was designed for easy, safe and cost-effective interconnection of sensors, actuators and switches. It transports both power and data over the same two-wire unshielded cable. SAP5S/SAP51 is used as a part of a master or slave node and works as an interface to the physical bus. The device realizes power supply, physical data transfer and communication protocol handling and is fully compliant with AS-Interface Complete Specification V3.0.
SAP5S/SAP51 can be programmed by the user to operate in Standard Slave Mode, Safety Mode or Master Mode. The special AS-I Safety Mode (SAP5S only) assures short response times regarding security related events. All configuration data are stored in an internal EEPROM that can be easily programmed by a stationary or handheld programming device. SAP5S/SAP51 is optimized for harsh environments by it’s special burst protection circuitry and excellent electromagnetic compatibility.
