The terminals of the control unit fulfill the Protective Extra Low Voltage (PELV) requirements. The PELV re-
quirements of a relay output are not fulfilled if a voltage higher than 48 V is connected to the relay output.
Connector pitch 5 mm, wire size 2.5 mm
Current input: –20...20 mA, R
Voltage input: –10...10 V, R
Differential inputs, common mode range ±30 V
Sampling interval per channel: 0.25 ms
Hardware filtering: 0.25 ms, adjustable digital filtering up to 8 ms
Resolution: 11 bit + sign bit
Inaccuracy: 1% of full scale range
Connector pitch 5 mm, wire size 2.5 mm
0...20 mA, R < 500 ohm
load
Frequency range: 0...500 Hz
Resolution: 11 bit + sign bit
Inaccuracy: 2% of full scale range
Connector pitch 5 mm, wire size 2.5 mm
Physical layer: RS-485
Termination by switch
Connector pitch 5 mm, wire size 2.5 mm
Physical layer: RS-485
Connector pitch 5 mm, wire size 2.5 mm
Input voltage range: -3...30 V DC
Logic levels: "0" < 5 V, "1" > 17 V.
Note: For the unit to start, both connections must be "1". This applies
to all control units (including drive, inverter, supply, brake, DC/DC
converter etc. control units), but true Safe torque off functionality is
only achieved through the XSTO connector of the drive/inverter
control unit.
Current consumption: 66 mA (continuous) per STO channel per R8i
module
EMC (immunity) according to IEC 61326-3-1
