If “External measurement cycles/Start” is not used, the EXT_RUN connection is
available as a digital input for interrogating a contact state. For this application the
cycle/TRIG parameter must be set to INTERN:
Logic assignment Contact open:
→ DI 1 = true
Contact closed: →
DI 1 = false
2 isolated relay contacts (N.O.). They can be assigned to the switching functions
(peak height monitoring) or be used as software-controlled outputs (e.g. for valve
actuation).
Signal designation: REL_1A ; REL_1B →
DO 0
REL_2A ; REL_2B
→
DO 1
Logic assignment DO .. = true →
Contact closed
4 analog output channels with a common reference point AO_COM
They can be assigned to measurement channels or be controlled directly by the
software, e.g. for outputting calculated concentration values.
Signal designation: AO_CH 1 + ; AO_COM →
AO - Channel 1
AO_CH 2 + ; AO_COM →
AO - Channel 2
AO_CH 3 + ; AO_COM
→ AO - Channel 3
AO_CH 4 + ; AO_COM →
AO - Channel 4
2 differential, high-impedance analog inputs. They can be assigned to
measurement channels or be read directly by the software.
Signal designation: AI_CH 0 + ; AI_CH 0 -
→
AI - Channel 0
AI_CH 1 + ; AI_CH 1 - →
AI - Channel 1
