QI-50-V-485

Current Transformer AC/DC TRMS - RS485 MODBUS

The QI-50-V-485 is a AC/DC current transformer, galvanically isolated from the measuring circuit. The device is in the function and appearance is very similar to a standard active TA, however, able to measure the DC component and AC TRMS. The transformer is equipped with RS485 Modbus serial output and an analog output 0-10V. Through the serial port can be configured freely span and zero and assign the Modbus address.

It’s possible to connect via serial RS485 to the QI-50-V-48 through a converter USB/232-485 for setting the parameters of zero and span and configuration of the Modbus addresses directly from your system of supervision, or using the free FACILE QI-50-V-485 software. You can download our software on www.qeed.it

Via the serial link RS485-USB you can connect to the QI-50-V-485 via the interface program FACILE QI-50-V-485. Using this software, free download from www.qeed.it, allows you to configure the processor by setting the START and STOP input and output (see diagram), you can set the Modbus address of the PC to which the query transformer and decide whether to make monopolar (only positive or negative values ) or bipolar (see diagram). If you are using bipolar function on AC current, the value read will be 0 A (5 V) because you are reading the average value. By means of dip-switch can configure the QI-50-V-485 to set the scale to 25 or 50A, the function monopolar (TRMS) or bipolar (mean value), the Modbus address (see register map below) up to a maximum of 15 addresses.

MOUNTING: The current transformer QI can be mounted in any position (see photo below), horizontal or vertical mounting, horizontal or vertical through the two hooks for DIN rail included in the box.

CAUTION: Magnetic fields of high intensity can vary the values measured by the transformer. Avoid installation near permanent magnets, electromagnets or iron masses that induce strong changes in the magnetic field. If any irregularity recommend reorient or move the transformer in the area most appropriate.

Any changes made by dip-switch required to switch off the power supply. It’s a safety condition in order to prevent any manumission on the device.
