CT input

Direct CT sensor connection reduces wiring and saves space

●CT input moduleQ68CT

The direct connection of the CT sensor*1 and the programmable controller has eliminated the need to connect a separate signal converter.
Very accurate measurements can be achieved with stable data conversion speed for load control of systems and devices, monitoring of operations, and control and monitoring of power systems.

*1: The CT (Current Transformer) sensor refers to an instrument transformer, a current sensor is essential for measuring alternating currents.

Direct CT sensor connection reduces wiring and saves space

Direct CT sensor connection reduces wiring and saves space

  • Directly connect to the CT sensor without an external signal converter.
    The AC current for up to eight channels can be measured with one unit, by that reducing the wiring steps and costs.
  • Set the CT sensor type (input range) for each channel. CT sensors with 0 to 5 A AC or 0 to 600 A AC can be used by one unit.

Predictive maintenance of devices by detecting the peak current!

Peak current detection function

  • The device can be serviced and troubleshooting performed by detecting the peak current.
    With a motor for example, the load applied on the motor is changed by the gear wear and damage, and the load current suddenly changes. The device trouble can be diagnosed by detecting the transient peak current at this time.

Peak current detection function

Input signal error detection function

  • Over-range (peak value over) of the CT input value can be detected. Since the flow of a large current exceeding the range of the measurement target can be detected, errors in the measurement target can be monitored.

Input signal error detection function

Input range setting Detection level
0…5 A (AC) Approximately 6.25 A (AC)
0…50 A (AC) Approximately 62.5 A (AC)
0…100 A (AC) Approximately 125 A (AC)
