For these isolators, the output type is configurable: 4-20 mA or 1-5 V. Two distinct check procedures are therefore
presented.
Current output:
a)
connect the power supply at the termination board supply terminals; connect the first multimeter A1 (current
mode) at the input terminals, in series with the resistor box Rc; connect the second multimeter A2 (current mode)
at the output terminals; set the supply at 24 V and switch it on; the green power LED must be on;
b)
set the resistor box to 780
Ω
; the input current must be within 19.50 and 20.50 mA; the output current must be
the same, with an error lower than 20 µA;
c)
set the resistor box to 5 K
Ω
; the input current must be within 3.50 and 4.50 mA; the output current must be the
same, with an error lower than 20 µA;
d)
set the resistor box to 1500
Ω
; the input current must be within 11.50 and 12.50 mA; the output current must be
the same, with an error lower than 20 µA;
e)
set the resistor box to 0
Ω
; the (short-circuit) input current must be within 25 and 30 mA; the output current must
be the same, with an error lower than 100 µA;
f)
disconnect the resistor box; the (open-circuit) output current must be lower than 1 mA;
Voltage output:
a)
connect the power supply at the termination board supply terminals; connect the first multimeter A1 (current
mode) at the input terminals, in series with the resistor box Rc; connect the second multimeter V1 (voltage mode)
at the output terminals; set the supply at 24 V and switch it on; the green power LED must be on;
b)
set the resistor box to 780
Ω
; the input current must be within 19.50 and 20.50 mA; the output voltage must be
equal to the input current multiplied by 250
Ω
, with an error lower than 10 mV;
c)
set the resistor box to 5 K
Ω
; the input current must be within 3.50 and 4.50 mA; the output voltage must be
equal to the input current multiplied by 250
Ω
, with an error lower than 10 mV;
d)
set the resistor box to 1500
Ω
; the input current must be within 11.50 and 12.50 mA; the output voltage must be
equal to the input current multiplied by 250
Ω
, with an error lower than 10 mV;
e)
set the resistor box to 0
Ω
; the (short-circuit) input current must be within 25 and 30 mA; the output voltage
must be equal to the input current multiplied by 250
Ω
, with an error lower than 30 mV;
f)
disconnect the resistor box ; the (open-circuit) output voltage must be lower than 250 mV;
