Characteristics of the inputs/outputs
■
■
Outputs
, channels 1...4, can be configured as:
■
■
semi-conductor outputs, positive switching (high side), short-circuit and over-
load protected
switching voltage
10 ... 30 V DC
switching current
max. 4 A
total current
max. 16 A
■
■
PWM outputs
PWM frequency
20 ... 250 Hz
pulse/break ratio
1 ... 1000 ‰
resolution
1 ‰
load current
max. 4 A (referred to the PWM value 1000 ‰.)
With smaller PWM values this current is reduced.
Additional output pins (RC) with low-pass filter for direct triggering of Danfoss
valves (type PVEH/S/M).
Can be configured as Danfoss output.
