6.5.3.5 Sub-D AI Connector
The 15-pin AI connector pin-out diagram is shown to the right.
The equivalent simplified schematic for the various types of I/O
pins is shown in the table below.
Digital Input (DI)
This input requires the use of a
switch with low resistance (relay,
switch, circuit breaker etc.) in
order to send a clean signal to the
DGND.
Analog Input (AI)
High resistance input (impedance
>40 k....100 kΩ) for an OA circuit
Digital Output (DO)
This is a quasi-open collector,
realized using a high resistance
pull-up against the internal sup-
ply. In condition LOW, it can carry
no load, only switch, as shown in
the diagram with a relay as an
example.
Analog Output (AO)
Output from an OA circuit, low
impedance. See specifications
table above.
6.5.3.6 Application Examples
Example A: Switching the DC Input with pin REM-SB
Note: A digital output, e.g. from a PLC, may be unable to cleanly pull down
the pin as it may not be of low enough resistance. Check the
specification of the controlling application. Also see pin diagrams
above.
In remote control, pin REM-SB is be used to switch the DC terminal of the unit
on and off. This function is also available without remote control being active
and can on the one hand block the DC terminal from being switched on in
manual or digital remote control and on the other hand, the pin can switch the DC on or off,
but not standalone. See below at “Remote control has not been activated”.
It is recommended that a low resistance contact such as a switch, relay or transistor is used
to switch the pin to ground (DGND).
Following situations can occur:

Remote control has been activated
