General Description
AS2702 (SAP4.1) is a new generation AS-Interface slave
device, which supports AS-Interface bus systems with up to
62 slave modules.
Each slave module is equipped with an AS2702 device,
which interfaces the module to the unshielded 2-wire AS-
Interface bus for serial bidirectional data communication
and power extraction.
Data communication over the AS-Interface takes place in
master slave fashion, which foresees that all slave devices
AS2702 connected to the bus are sequentially and cyclicly
addressed by a single, central master unit. Data on the AS-
Interface bus are Manchester encoded and can be found as
sin2-pulses with a Vpp of between 3V and 8V on top of the
bus’ dc voltage of nominally 30V.
AS2702 regulates the nominal dc bus voltage of 30V
internally
down to 5V to supply it’s internal circuitry
including a 16 x 8 bits EEPROM, as well as down to a
nominal supply level 24V with a max. loading of 35mA for
the actuators and sensors connected to it at the field side.
Each slave device AS2702 may interface to up to 4 sensors
or 3 actuators. An AS-Interface bus system based on
AS2702 may hence link as many as 248 sensors and 186
actuators to a single master unit.
Slave device AS2702 (SAP4.1) is system compatible with
predecessor device AS2701A (ISA3+):
slave modules equipped with AS2702 (SAP4.1) will run in
existing AS-Interface bus systems based on AS2701A
(ISA3+).
The AS-Interface concept is well established as a
standardized digital bus system for industrial automation.
Key Features

the sensors and actuators
24V power supply for the sensors and actuators
Periphery fault input to signal hardware failure of the
sensors and actuators
Integrated 16 x 8 bit EEPROM to store (5 + 1)-bit slave
address and settings
2 LED outputs to optically flag slave unit operation
