(Options for AI 638 per EC- Certificate of Conformity

PTB 00 ATEX 2128)

Two independent binary inputs, supplied with the basic

device, for connection of external switches.

A connected switch is loaded with 3.5 V, 150 µA.

The binary inputs can be used for diagnostics or also

configurable for the control functions:

Switch 1 Switch 2 Actuator control function

close close normal operation

open close go to stop at 0 %

close open go to stop at 100 %

open open hold last position

Types of protection and temperature classes as basic device.

To this electric circuit only passive electric circuits galva-

nically separated from earth may be attached.

The electric circuit has the following maximum values:

Uo= 7.88 V, Io= 11.4 mA, Po= 23 mW

Characteristic is linear

For the maximum values of outer inductances and capa-

cities Lo and Co refer to the following table (Li and Ci

included):

IIC IIB

0.1 2.7 0.1 15

0.01 4.7 0.01 27

The electric circuits of "2 binary inputs" are galvanically

connected with all other circuits but separated from earth.
