Purpose
OUT,1 OUT2
(relay, optional
optocoupler)
Control output ‘heating’ or ‘cool-
ing’(relay or optionalor Open/Closed;
Limit contact; Timer; optocoupler)
Programmer ‘End’ *
OUT3 (logic or
optional relay)
Same as OUT1 and OUT2
OUT3
(continuous)
Control output; Process value; Set-
point;Control deviation; Measure-
ment values of INP1/INP2; Trans-
mitter supply
* All logic signals can be ”OR-linked”.
Output values can also be forced via interface.
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
Switching
cycles
(electrical):
for I=1A/2A:
?
800,000/500,000
(at 250V AC, 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.
