OUTPUTS
SURVEY OF OUTPUTS
* All logic signals can be ”OR-linked”.
RELAY OUTPUTS OUT1, OUT2, OUT3
Contact type: normally open *
Max. contact rating: 500 VA, 250 V, 2A resistive load, 48...62 Hz,
Min. contact rating: 6V, 1 mA DC
Swithing cycles (elec
-
trical):
for I= 1A/2A:
? 800.000 / 500.000
(at ~ 250V (resistive load))
* Versions with two relays OUT1 & OUT2 have a common terminal.
Note:
If the relays OUT1, 2 and 3 are used to operate external
contactors, these must be fitted with RC snubber circuits to
manufacturer specifications to prevent excessive voltage peaks at
switch-off.
OPTOCOUPLER OUTPUTS OUT1, OUT2
(OPTIONAL)
Galvanically isolated optocoupler outputs. Grounded load:
common ‘plus’ control voltage
Switch rating: 18...32 V DC; max. 70 mA
Internal voltage drop: ß 1 V at Imax
Built-in protective circuits:
for short circuit, wrong polarity
Note:
A protective diode for inductive loads must be fitted externally.
OUT3 UNIVERSAL OUTPUT
Galvanically isolated from the inputs. Parallel current/voltage
output with common ‘minus’ terminal (combined use only in
galvanically isolated circuits).
