Control unit (RDCU/RMIO) connection data
Analog inputs
With Standard Control Program two programmable differential current inputs (0 mA /
4 mA ... 20 mA,
R
in
= 100 ohm) and one programmable differential voltage input (-
10 V / 0 V / 2 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.
Inaccuracy
±0.5% (Full Scale Range) at 25
°
C (77
°
F). Temperature coefficient: ±100 ppm/

C
(±56 ppm/°F), max.
Constant voltage output
Voltage
+10 V DC, 0, -10 V DC ± 0.5% (Full Scale Range) at 25 °C (77

coefficient: ±100 ppm/°C (±56 ppm/°F) max.
Maximum load
10 mA
Applicable potentiometer
1 kohm to 10 kohm
Auxiliary power output
Voltage
24 V DC ± 10%, short circuit proof
Maximum current
250 mA (shared between this output and optional modules installed on the RMIO)
Analog outputs
Two programmable current outputs: 0 (4) to 20 mA,

F) max.
Digital inputs
With Standard Control Program six 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).
Thermistor input: 5 mA, < 1.5 kohm
“1” (normal temperature), > 4 kohm
“0”
(high temperature), open circuit
“0” (high temperature).
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.
Insulation test voltage
500 V AC, 1 min
Logical thresholds
< 8 V DC
“0”, > 12 V DC
“1”
Input current
DI1 to DI 5: 10 mA, DI6: 5 mA
Filtering time constant
1 ms
