Control unit (RDCU/RMIO) connection data
Analog inputs
RDCU (A43, PVS800 master control program): one programmable
differential current input (0 mA / 4 mA … 20 mA, R
in
= 100 ohm).
RDCU (A41, PVS800 inverter control program): two programmable
differential current input (0 mA / 4 mA … 20 mA, R
in
= 100 ohm) and one
programmable differential voltage input (-10 V ... +10 V, R
in
= 200 kohm).
The analog inputs are galvanically isolated as a group.
Insulation test voltage 500 V AC, 1 min
Max. common mode voltage
between the channels ±15 V DC
Common mode rejection ratio > 60 dB at 50 Hz
Resolution 0.025% (12 bit) for the -10 V … +10 V input. 0.5% (11 bit) for the
0…+10 V and 0…20 mA inputs.

Digital inputs
RDCU (A43, PVS800 master control program): two programmable
digital inputs (common ground: 24 V DC, -15% to +20%) and a start
interlock input. Group isolated, can be divided in two isolated groups (see
Isolation and grounding diagram below).
RDCU (A41, PVS800 inverter control program): one programmable
digital input (common ground: 24 V DC, -15% to +20%) and a start
interlock input. Group isolated, can be divided in two isolated groups (see
Isolation and grounding diagram below).
Internal supply for digital inputs (+24 V DC): short-circuit proof. An
external 24 V DC supply can be used instead of the internal supply.
