'Analog'/'Digital'

[V/mA/]/[bar/kPa/psi]/

Description

Appears only for voltage variants. For current var-

iants, 'Input type' = 'Analog'.

– 'Analog': An analogue voltage / current value via

setpoint value (+) and setpoint value (-) deter-

mines the setpoint pressure.

– 'Digital': One of 8 setpoint values is specified via

three digital 24 V inputs. For this, the three inputs

are interpreted as a binary number with 3 bit.

The assignment is as follows:

– Setpoint value (+): DI0 or least significant bit

– Setpoint value (-): DI1

– Actual value output: DI2 or most significant bit

The value 000 means 0 bar and cannot be edited; the

remaining 7 values can be set in 'Input values'. There

is no actual value output in this mode.

Appears only if 'Input type' = 'Analog'.

Determines the unit in which the setpoint value is

displayed on the main screen.
