Pors-GY Universal Input Temperature Transmitter

1. Summary
Pors-GY22 (GY11) provides two-channel (one-channel) transmitters or signal isolators.

2. Features
◆ It provides 2 channels of configurable inputs, and supports multiple voltage, RTD, thermocouple inputs with auto reference junction compensation. If parallel connected to an external precise resistance, it accepts current signal input. Each channel has its own digital filtering and can adjust its filtering degree.
◆ It generates two isolated current outputs, 4-20mA or 0–20mA. The range of retransmission output can be freely defined.
◆ This model uses high performance hardware, which leads to greatly decreased temperature drift and interference among the two channels. As a result, this multi-channel instrument achieves the same measurement accuracy and anti-interference ability as that of single channel instrument.
◆ It generates digital adjusted current output without potentiometer, making the current output precise and stable.
◆ The model is DIN rail mounted. Its width is only 22.5mm. The instrument can be easily configured by connecting to our E8 handset display.
◆ Power supply of 100-240VAC or 24VDC.
◆ Meets EMC standards. Its power and all I/O terminals pass 4KV/5KHz EFT test and can work reliably under interference.

4. Terminals and Indication Lights and Wiring
Terminal 1 & 2: power supply of 100-240VAC or 24VAC/DC
Terminal 5 & 6: channel 1 current retransmission output
Terminal 7 & 8: channel 2 current retransmission output
Terminal 14～16: channel 1 input
Terminal 10～12: channel 2 input
Indicator OP1～OP2: indicate the outputs of channel 1 and 2.
The luminosity of the light indicates the magnitude of the output.
Indication light--- MODE:
When the light flickers even faster, at a rate of once every 0.3 second, it indicates severe errors such as input exceeding its acceptable range.
When the light is off, it indicates that the instrument has no power or it is out of order. When the light is on (for at least longer than 8 seconds), it indicates that the instrument has power on but is out of order.
