Electrical data

Supply voltage:	+ 18 … 29 VDC (stabilized) in dual-channel operation + 10 … 18 VDC (stabilized) in single-channel operation You must use a power supply with Safety Extra Low Voltage (SELV) or Protective Extra Low Voltage (PELV).
Residual ripple:	< 100 mVpp
Reverse voltage protection:	integrated
Power input:	max. 200 mA @ 24 VDC without loading the output for the door zone indication
Interfaces:	RS-485
Protection of the outputs/ interfaces:	RS-485 output: short-circuit-proof output door zone indication: short-circuit-proof to GND, but not to +24 V
Cable length:	according to EIA RS-485 specifications
Maximum operating time:	20 years, reduced depending on ambient conditions

Environmental conditions

Storage temperature:	-20 °C … +85 °C
Operation temperature:	-20 °C … +70 °C standard version -20 °C … +75 °C extended requirements Note that these specifications for both versions only apply up to an operating altitude of 2000 m above sea level. Above this limit, the maximum ambient temperature is lower due to the lower cooling capacity of the ambient air.
