Passive digital output V1 / V2, V3 / V4 (plug-in card) 
An additional binary output can be implemented via the ‘Passive 
digital output (green)’ plug-in module. 
Can be configured as an output for flow direction signaling, 
alarm output etc. via on-site software.

The plug-in module can be used in slot OC1 or OC2.

Active digital output V1 / V2, V3 / V4 (plug-in card) 
An additional binary output can be implemented via the ‘Active 
digital output (white)’ plug-in card. 
Can be configured on-site as a logical output for V1 / V2 (flow 
direction signaling, alarm output, etc.) via software. 
Can be configured on-site for V3 / V4 as a frequency output, 
pulse output or logical output via software.

The plug-in module can be used in slot OC1 or OC2. 
External voltage cannot be connected to the active binary 
output. 
Only one of the two digital output plug-in cards (passive or 
active) will be supported at the same time. 
 
Note 
Requirements for inputs and outputs 
For reasons of electromagnetic compatibility (EMC), shielded 
cables should be used in certain output configurations; this is 
presented in Table Use of shielded cables on page 48.
