Auxiliary input
( IN CT)
For current transformer
50mAac, 50/ 60Hz, Ri= 10&
Digital input
( IN1/ IN2)
PNP: Ri = 4, 7K& ( 24V, 5mA) insulation
1500V
NPN: voltage-free contact.
Function configurable among man/ auto
selection, local/ remote ( setpoint from
serial line, setpoint1/ setpoint2) ;
Set/ reset outputs, start/ stop tuning
functions, software off/ on, reset alarm
memory, hold.
OUTPUTS
4 configurable outputs:
• OUT1 relay ( switching contact only with
OUT2 relay)
• OUT2 available in relay, logic or triac
• OUT3 available in relay, logic,
continuous or analog retransmission
• OUT4 relay or logic.
The outputs are freely assignable to control
and alarm functions ( in " OR" or " AND" ) .
They can be slaved to a faceplate key or to
the auxiliary digital input.
Relay
( order code R)
With rating: 5A/ 250Vac/ 30Vdc, cosÕ = 1
Logic
( order code D)
24Vdc, Rout= 100& ( 10V/ 20mA)
Triac ( order code T)
24...240Vac ± 10% , 50/ 60Hz, 1A max.
I2t = 128A2sec.
Leakage current 1.5mA max a 200Vac.
Continuous ( order code C)
0...10V, 0/ 4...20mA, on 500& max
only for heat/ cool control output.
Retransmission
( order code W)
0...10V, 0/ 4...20mA, on 500& resolution
12bit, useful for retransmission of the
variable.
