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.
- DIN rail mounted type, 22.5mm installation width.
- Adopt high-performance components, significantly reduce temperature shift and mutual interference between channels.
- Digital-correct current output, no potentiometer, improved the accuracy and stability for current output.
- Can be programmed by E8 handheld display with 1394 wiring, such as input type, define range of retransmission output.
