DESCRIPTION

The BiSS to PC-USB Adapter enables BiSS or SSI

sensors to be connected to a PC easily and at low

cost. The USB port supplies the adapter as well as

the connected sensor, for which the 5V (up to 50 mA,

through Pin 4)* and 12 V (up to 90 mA, through Pin 1)*

as galvanically isolated voltages are available. An ex-

ternal wall power supply can also be connected to de-

liver other voltages or higher currents. The BiSS/SSI

communication is accomplished by differential RS422

wires with separate potentials and cycle rates of up to

10 Mbit/sec.

Technical Data BiSS Interface

• Synchronously triggered measurement data collec-

tion from up to 3 BiSS sensors or one SSI encoder

• BiSS data rates up to 10 Mbit/sec., SSI up to

4 Mbit/sec.

• Protocol compatible with BiSS Master iC-MB3z

• USB 2.0 compatible

• Galvanic encoder signal isolation

• Galvanically isolated sensor supply sourced from the

USB port (+12 V / 90 mA, +5 V / 50 mA)*

• Plug-in power supply can be connected for sensors

with higher power needs

* 100 mA for +5V and +12 V available starting from 2008

42 x 95 x 24 mm
