Out 1 and 2 - SSR
Type: not
isolated voltage output
- Logic level 1:
14V @ 20 mA max.
24 V @ 1 mA.
- Logic level 0:
< 0.5 V D.C.
Out 1 and 2 - TRIAC
Switching mode
: isolated zero crossing type.
Rated current : from 50 mA to 1 A.
Rated voltage : from 24 V
RMS
to 240 V
RMS
-10% +15% (50-60
Hz).
Load type : resistive load only
I
2
t for external fuse : 128
Out 3 and 4
Function
: singularly programmable as:
- Control output
- Alarm output
- Event output.
- Servomotor drive (Out 3
s
, out 4
t
)
Type : Relay .
Relay type : SPST
Contact rating : 3 A @ 250 V on resistive load.
Notes :
1) The commons of the out 3 and 4 are connected together with
the same rear terminal.
2) When OUT 3 and 4 are used as independent relay outputs
the addition of the two currents must not exceed 3 A.
Servomotor output
Type
: Two relays with interlocked contact (Out 3 and 4).
Servomotor output type:
- Close loop
- Open loop with feedback for valve position indication only
- Open loop without feedback.
Feedback potentiometer input : from 100
W
to 10 k
W
.
Servomotor travel time : From 12 s to 3 minutes.
Servomotor dead band : From 1 % to 50 % of the feedback
span or of the valve travel time.
Analog outputs
Out 5 and 6
Function
: Programmable as
- Control output
- Analog retransmission of the measured value
