Note:
When the SDCS-CON-4 control board with the SDCS-IOB-
2 I/O board is installed, terminals X6: and X7: on the
SDCS-CON-4 must not be used.
Output value Signal definition by
K1...K5, K8 Firmware
K6, K7 Firmware
X4:, X5: are screw-clamp terminal types for leads up to 4 mm² cross-
sectional area.
Default values are shown within the software diagrams.
The ground potential of the digital outputs may vary within ±100 V to
each other.

Input resistance: see diagram.
Input smoothing time constant: see diagram.
Smoothing time constant of channel 7 and 8 can be changed; see
fig. before.
Power supply for digital inputs: 48V / ≤ 50mA; not galv. isolated
from the DCS electronics!
If the inputs are supplied from the internal +48 V (X7:3 and/or X7:4) a
connection must be done from either X7:1 and/or X7:2 to ground of
the DCS 500 module. In default condition ground is identical to the
converter's frame.
If the inputs are supplied by any external source (+48 V DC, 115 V AC
or 230 V AC) the neutral line / - line must be connected to either X7:1
or X7:2. If the inputs should be controlled with the same voltage level,
but from two different voltage sources, having probably two different
ground levels, the first neutral line should be connected to X7:1 and
the second to X7:2. In this case the jumpers Wx connecting the inputs
to X7:2, but controlled by the source, connected to X7:1, must be cut
off.
The same method is needed for the other jumpers Wx.
High frequency grounding is done by 100 nF capacitor.
