CT-100/CT-150 Series User’s Manual

In the voltage output “V”-versions of the transducers the current output pin I
S
(pin #6) and its return (pin #1 on “C” and pin #7 on “P”) are not present.
Please note that output impedance for the “V”-version models is 50 Ω and it is
low-pass filtered with a 0.5-µs time constant.
2.5.4
STATUS Signal
A STATUS signal, obtained from the outputs of an optocoupler phototransistor
(
and
Status-
, pins #8 and #3 on the “C” version and pins #4 and #5 on the “P”
version respectively) is present on all versions of the CT-100/CT-150 Series. Please
note that the OK- signal is not internally connected to the ground potential and can be
connected to an external reference potential. A green LED is also present on the front
side of the DCCT indicating the correct operation of the devices.
A pull-up resistor is needed (between the OK+ and some supply voltage referred
to the OK- potential) in order to correctly obtained the correct signaling.
Two examples on how to connect the OK+ and OK- signals are hereafter
presented in
Error! Reference source not found.

Note that the connection scheme presented in
potential and the OK_SIGNAL is at low level (<0.4V) if the CT-100/CT-150 Series
