One Introduction to the Performance of ZY-XH Intelligent Signal Isolator:
Input single or dual channel current or voltage signals, transmit isolated single or dual channel current or voltage signals, and improve the electrical isolation performance between input, output, and power supply.

II Technical characteristics of signal isolators:
This product adopts advanced digital technology, and has many advanced properties that traditional analog isolators do not have. It has excellent performance in suppressing high and low frequency interference signals. It can still be reliably applied even in high-power control systems. It uses digital calibration, zero free and full potentiometer, automatic dynamic calibration zero, automatic temperature drift compensation and many other advanced technologies internally, and meets the anti electromagnetic interference requirements of the fourth class (harsh industrial site) environment specified in IEC61000-4-4:1995. The application of this series of technologies ensures the stability and reliability of the product scientifically.

III Applicability of isolators:
It can be used in conjunction with unit combination instruments and DCS, PLC and other systems, and has a wide range of applications in major projects in industries such as oil fields, petrochemicals, manufacturing, power, metallurgy, etc.

Technical parameters of isolator:
Isolation system transmission accuracy: ± 0.1% × F • S

Isolator temperature drift: ± 0.0035% × F • S/℃ (35ppm/℃)

Input impedance: Current: ≤ 60 Ω; Voltage: ≥ 500KΩ

Current output allows external load impedance:
0~300 Ω when outputting 4-20mA; 0-600 Ω when outputting 0-10mA,
0(1)-5V：≥500KΩ； 0-10V:≥ 1MΩ
Please specify when placing an order that a larger load capacity is required.

Isolator power supply: AC 95~265V
DC 20~32V

Input power: 0.9~1.8W (depending on the model, please refer to the appendix of the product manual for the calculation method of input power)

The output state when the input signal of the isolator is disconnected:
The output status of the isolator can be set in two modes: following mode and alarm mode

4 Isolator selection:

Five Selection instructions for universal intelligent isolators:
1. Single channel products can have up to two outputs; Dual channel products can only correspond to one output per channel.
If different input signals are required for dual channel products, please contact our company for ordering
3. Communication products with only a single input channel and a maximum of one analog signal output.

Isolator panel indication:
PWR： Power indicator light (green);
ALM： Input signal alarm indicator light (red);
The indicator light does not light up when the isolator is in normal working condition;
Flashing when the input signal of the isolator is faulty; When the input signal exceeds the range, it stays on for a long time.

Description of Universal Intelligent Isolator:
1. There are DC and AC power supply forms for instruments, please distinguish them carefully! 220V power supply
The power cord of the product is connected between the power terminals L and N in the diagram, with L connected to the phase wire and N connected to the neutral wire.
2. If the grounding wire is reliably grounded, it can ensure that this product meets the requirements of the third category of industrial site environment anti electromagnetic interference in IEC61000-4-4:1995. If there is no grounding wire, this indicator will be reduced, but it can still ensure its application in industrial site environments below the second category, which is applicable to the vast majority of industrial sites.

VI Isolator calibration:
This isolator adopts intelligent digital design, which can ensure long-term accuracy within the range specified in this manual. If calibration is required, please select the dedicated handheld Chinese programmer provided by our company for operation Isolator
