etra’s CTC Series Split Core
Current Transducers combine
S
accurate magnetic current
sensing with signal conditioning electronics. They are available in either
24 VDC loop power or self-powered,
which means they are easy to install
and put into operation. Their selfgripping, compact split core design
makes it easy to retrofit into existing
equipment
Each unit has a three position
slide switch to select the most suit-
able range for the application. The 0 to
5V and 4 to 20 mA output units have
30/60/120 Amp sensing ranges. The 0
to 10 V output units have a 20/100/150
Amp sensing range.
In addition, when used with the optional
CCR-24 or CCR-12 power relay module
w/LED indicator, the CTC can be used
for remote motor startup.
These units are ideal for monitoring cur
rent in PLCs (power line carrier communications) & AMR systems or in remote
control system of SCADA software for
automation & supervision, security, condition monitoring in protection systems
and for predictive maintenance of conveyers, pumps or HVAC motors.
