Current Remote Probe
The P112I-4 Current Remote Probe is the current counterpart to the voltage probe. The device provides four current inputs up to ±2 A for direct connection to current transducers (CTs) and a sample rate of up to 2 MS/s. It also offers voltage inputs for current clamps or Rogowski coils. The P112I-4 variant features also build-in power supply for CTs.
Current accuracy of 0.025% reading +0.01% range
Bandwith of 2.3 MHz (-3dB)
Single fiber connection back to GN800B power analyzer card
60 V isolation to prevent ground loops
Standard 9 pin D-Sub connector for current transducer or voltage input for current clamps with separate BNC connector
Distributable
Can be used as part of a distributed measurement system where modules are situated close to the measurement object with cable length up to 100 metres. Ideal for large scale measurements.
Minimise EMC issues
Receiver card and mainframe separate for closer positioning of card to measurement point, reducing EMC interference. Glass fibre cables enable EMC-free data transfer to mainframe, ensuring EMC immunity through fibre-optic connections.
Safe and simple cabling – less is more
Our decentralised receiver card reduces cabling needs significantly, while the use of glass fibre cables ensures rapid and EMC-free data transfer capabilities of up to 100 metres.
