Ordering considerations

Precautions for PY9000 product ordering

1. Instrument power supply voltage selection:
220 VAC AC voltage
24 VDC DC voltage

2. Type of instrument input signal (matching with user transmitter / sensor output)
Type of 4-20mA two-wire pressure / liquid level / temperature transmitter
0-5vdc three wire pressure / liquid level / temperature transmitter
0-10vdc three wire pressure / liquid level / temperature transmitter
2.0 / 3.3mV pressure sensor / load cell
Rs485-rtu digital communication signal transmitter

3. Instrument output type (matching with user acquisition and control system)
Two way relay output + PID 4-20mA feedback
Two relay outputs + one relay output
Two way relay output + PID 0-10vdc feedback
Two way relay output + PID 0-5vdc feedback
Two relay outputs + one digital RS485 output

4. Users should understand the installation environment and installation mode of the product
Indoor or outdoor installation (power box protection required);
Ambient temperature;
Vibration range of equipment;
Whether the installation space meets the product dimensions;

Precautions for use

The type and scope of instrument power supply shall be provided according to the requirements of instrument;
Instrument 16 foot grounding;
Power supply and signal wire shall be correctly wired according to the requirements of product specification ordered;
The output power of the relay at the output end of the instrument shall not exceed 220v/1a or 24v/1a;
Pay attention to the protection instrument access and outgoing cable. When the span of field use is too large, it is recommended to use metal pipe to protect or overhead;
The product is installed in a ventilated, dry and non corrosive environment. Protective devices are installed in the open air to avoid direct sunlight;
Avoid direct access to user devices or appliances causing interference as far as possible;
