CGS XT-T1 Betriebsanleitung Seite 120

The specifications in brackets are limits that apply according to NAMUR recommendation NE 43.
Signal type
0 to 10 V
E
0 to 20 mA
4 to 20 mA
2...10 V
Behaviour after power down
A voltage of 0 V is output during the device's initialization phase (depending on the configuration). Once the initializati-
on is complete, the output signal depends on the signal of the source and the configured signal type.
9.7 Digital inputs
The device is equipped with two digital inputs that are provided to connect a potential-free contact.
Parameter
Inversion
NOTE!
Digital input 1 can only be used as an alternative to digital input 3.
If digital input 3 (logic output 0/14 V) is activated by assigning a signal source, digital input 1 is inactive.
NOTE!
Digital input 2 can only be used if the analog input has not been configured with signal type 0(2) up to 10 V.
9.8 Digital outputs
The device has a digital output (logic output 0/14 V) and up to two relay outputs (normally open contact). On top of
that, up to four additional digital outputs are optionally available depending on the device type (relay, logic 0/14 V,
PhotoMOS relay).
Parameter
Source
Inversion
NOTE!
Digital input 3 can only be used as an alternative to digital input 1.
If digital input 3 (logic output 0/14 V) is activated by assigning a signal source, digital input 1 is inactive.
Behaviour after power on
The outputs are not active during the device's initialization phase (depending on the configuration). Once the initializa-
tion is complete, the output signal corresponds to the signal of the source (inverted if neces sary).
