SAP5S / SAP51
Universal Actuator-Sensor Interface IC
Brief Description
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
SAP5S only) 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.
