Power supply (XPOW)
24 V (±10%) DC, 2 A
External power input.
Two supplies can be connected to BCU for redundancy.
Connector pitch 5 mm, wire size 2.5 mm 2 Relay outputs RO1…RO3
(XRO1…XRO3)
250 V AC / 30 V DC, 2 A
Protected by varistors
Connector pitch 5 mm, wire size 2.5 mm 2 +24 V output (XD24:2 and XD24:4)
Total load capacity of these outputs is 4.8 W (200 mA / 24 V) minus
the power taken by DIO1 and DIO2.

Digital inputs/outputs DIO1 and DIO2
(XDIO:1 and XDIO:2)
As inputs: 24 V logic levels: “0” < 5 V, “1” > 15 V. R
in
: 2.0 kohm. Fil-
tering: 1 ms. Input/output mode selection by paramet-
ers.
As outputs: Total output current from +24VD is limited to 200 mA
DIO1 can be configured as a frequency
input (0…16 kHz with hardware filtering
of 4 microseconds) for 24 V level square
wave signal (sinusoidal or other wave
form cannot be used). DIO2 can be con-
figured as a 24 V level square wave fre-
quency output. See the firmware manual,
parameter group 11/111.
