17 .1 Electrical data

Mains voltage:
BCU..Q: 120 V AC, -15/+10%, 50/60 Hz, ± 5%,
BCU..W: 230 V AC, -15/+10%, 50/60 Hz, ± 5%.
Power consumption: 10 VA,
for grounded and ungrounded mains.

with UV sensor or flame rod.
For intermittent or continuous operation.
Flame signal current:
Ionization control: 1 – 25 �A,
UV control: 1 – 35 �A.
Ionization cable, UV cable:
max. 50 m (164 ft).
Contact rating:
Valve outputs V1, V2, V3 and V4 (terminals 60, 61, 62,
63 and 64): max. 1 A each, cos φ = 1.
Actuator outputs (terminals 65, 66 and 67): max. 1 A
each, cos φ = 1.
Air valve output (terminal 65): max. 1 A, cos φ = 1.
Ignition transformer (terminal 51): max. 2 A.
Total current for the simultaneous activation of the
valve outputs (terminals 60, 61, 62, 63 and 64) and of
the ignition transformer (terminal 51), protected by F1/
F2: max. 2.5 A.
BCU 460, BCU 465 · Edition 11.19
Total current for the simultaneous activation of the
outputs for air valve and actuator (terminals 65, 66
and 67): max. 2 A.
Signalling contact for operating and fault signals:
max. 1 A, cos φ = 1 (external fuse required).
Number of operating cycles:
The fail-safe outputs (valve outputs V1, V2, V3 and V4)
and the air valve output are monitored for correct func-
tioning and are thus not subject to a max. number of
operating cycles.
Control actuator (terminals 60, 61, 62, 63 and 64):
1,000,000,
signalling contact for operating signals (terminals 95,
96 and 97):
1,000,000,
signalling contact for fault signals (terminals 80, 81
and 82):
max. 25,000,
On/Off button:
max. 10,000,
Reset/Information button:
max. 10,000.
