Digital input (ADI)
When AI = digital input (ADI function), receive switching signal with
over 6V
AO Analogue output Voltage 0 - 10V
GND Power supply ground Analogue and digital ground, 0V
DI1 - DI4 Digital input Valid when short-connect with GND
DO Digital output
Open collector output
• External voltage 10 - 30VDC, max. current 50mA
Or
High speed pulse output (F15.19 = No. 38)
• Max. frequency 10kHz (set by F16.26)
R1A, R1B, R1C Relay output
