A.2) Current transformer input
SAFETY NOTE:
1) Do not run current transformer input wiring with AC
power cables.
NOTE:
1) The minimum active period to perform this
measurement is 50 ms.
2) The input impedance is 10 Ω.
3) The maximum input current is 50 mA.
This input measures the current used by OUT 1.

OUT1: Contact rating of 3 Amps/250 Vac resistive load.
OUT2: Contact rating of 2 Amps/250 Vac resistive load.
OUT3: Contact rating of 2 Amps/250 Vac resistive load.
The output 2 and the NO contact of the output 1 are
protected by varistor from inductive load with an
inductive component up to 0.5 A. The number of
operations is 1 x 10

at specified rating.
Notes:
1) To avoid electric shock, cponnect power line at the
end of wiring procedure.
2) For power connections, use no. 16 AWG or larger
wires rated for at least 75°C.
3) Use copper conductors only.
4) Don’t run input wires together with power cables.
5) Relay output and SSR driver output are both available.
When a relay output is desired, it is necessary to enable
the relay output, and viceversa. See “Preliminary
Hardware Settings.”
