Type Terminal Name Description
Digital
outputs DO1 CME Digital output 1 Optically-coupled isolation, dual-polarity
open-collector output
Output voltage range: 0 to 24 V
Output current range: 0 to 50 mA.
Note that CME and COM are internally
insulated, but are shorted externally by a
jumper. In this case, DO1 is driven by +24
V by default. Remove the jumper link if
you need to apply external power to DO1.
FM COM High-speed pulse
output Controlled by F5-00 (FM terminal output
selection).
Max. output frequency: 100 kHz.
When used as an open-collector output,
