114 Technical data
Control unit (JCU-21) connection data
Power supply 24 V (±10%) DC, 1.6 A
Supplied from the power unit of the drive, or from an external power supply
through connector XPOW (pitch 5 mm, wire size 2.5 mm
2
).
Relay outputs RO1…RO2
(XRO1 … XRO2)
Connector pitch 5 mm, wire size 2.5 mm

250 V AC / 30 V DC, 2 A
Protected by varistors
Note: At installation sites between 2000 meters (6562 feet) and 4000 meters
(13123 feet), the Protective Extra Low Voltage (PELV) requirements are not
fulfilled if a relay output is used with a voltage greater than 48 V.

frequency input (0…16 kHz)
for 24 V level square wave
signal (sinusoidal or other
wave form cannot be used).
DIO2 can be configured as a
24 V level square wave
frequency output. See
Firmware manual, parameter
group 12.
