3.5.4.5 Overview of the D-sub socket
3.5.4.6 Simplied diagram of the pins
++
Digital Input (DI)
It requires to use a switch with low resis-
tance (relay, switch, circuit breaker etc.) in
order to send a clean signal to the DGND.
V~0.5
AGND
Analog Input (AI)
High resistance input (impedance >40 kΩ)
for an operation amplier circuit.
4K7
12 V
+10V
Digital Output (DO)
A quasi open collector, realized as high re-
sistance pull-up against the internal supply.
In condition LOW it can’t drive any load, only
sink small current, as shown in the diagram
with a relay as example.
V~2
AGND
Analog Output (AO)
Output from an operation amplier circuit,
low impedance. See specications table
above.
3.5.4.7 Application examples
a) Switching the DC input with pin REM-SB
A digital output, e.g. from a PLC, may be unable to cleanly pull down the pin as it may not
be of suciently low resistance. Check the specication of the controlling application.
Also see pin diagrams above.
In analog remote control, pin REM-SB is be used to switch the DC input of the device on and off. This function
is also available without analog remote control being active and can on the one hand block the DC input
from being switched on in manual or digital remote control and on the other hand the pin can switch the DC
input on or off, but not standalone. See below at “Remote control has not been activated”.
REM-SB cannot serve as a safety stop switch to securely deactivate the DC input in case
of emergency! For that an external emergency stop system is required.
It’s 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
During remote control via analog interface, only pin REM-SB determines the states of the DC input, according to the level
denitions in
3.5.4.3
. The logical function and the default levels can be inverted by a parameter in the setup menu of the
device. See
3.4.3.1
.
If the pin is unconnected or the connected contact is open, the pin will be HIGH. With setting “Analog in-
terface” -> “REM-SB level” being set to “Normal”, it requests to switch the DC input on. So when activating
remote control, the DC input will instantly switch on.
