Q68CT

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

• *1.The CT (กระแสไฟฟ้า Transformer) sensor refers to an instrument transformer, a กระแส sensor is essential for measuring alternating กระแสs.

Direct CT sensor connection reduces wiring and saves space

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

การบำรุงรักษาเชิงคาดการณ์ of อุปกรณ์s by detecting the peak กระแส.

Peak กระแส detection ฟังก์ชัน

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

อินพุต signal error detection ฟังก์ชัน

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

อินพุต ช่วง 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)
0…200 A (AC)	Approximately 250 A (AC)
0…400 A (AC)	Approximately 500 A (AC)
0…600 A (AC)	Approximately 750 A (AC)
