AS2702

AS-Interface Slave IC

DATA SHEET

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.
