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 kW.
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
