Renesas Electronics SAP51 Universal Actuator-Sensor Interface IC
Renesas Electronics SAP51 Universal Actuator-Sensor Interface IC is a CMOS integrated circuit for AS-I networks. The low-level field bus AS-I (Actuator Sensor Interface) is designed for the easy and safe interconnection of sensors, actuators, and switches. This device transports both power and data over the same two-wire unshielded cable. The Renesas Electronics SAP51 is used as a part of a master or slave node and works as an interface to the physical bus.
