dOutput switch delay without additional power supply
max. delay time per switch change (capacity load time)
with every SwitchME KNX 400 ms
!Note: Voltage overload protection is integrated into the device. This halts active switch proce-
dures and retains the last relay position in the device memory. If a power drop falls into the
cut-off range, this function may prevent the deactivation of a non-switched relay. If the voltage
(capacity of the relay driver) again climbs into the active range, the relay can be reactivated
again in the memory after the interrupted state. If the load capacity is insufcient the delay time
for the switch change is approx. 0.4 s.
dOutput switch delay with additional power supply
max. delay time upon switch change (capacity load time)
SwitchME 8 KNX 100 ms
SwitchME 12 KNX 100 ms
!Note: With some applications a synchronous on/off relay switch is required, because exces-
sive delays are not permissible. In such cases an additional 24-30 V DC power supply can be
connected. The maximum anticipated power with an active relay is 24 mA, and 4 mA with an
inactive relay. If there is insufcient switching capacity, the switch delay for a status change is
approx. 100 ms.
