Key Features：
- Eight completely electrically isolated analog input channels, each of which can be independently configured.
- Multi-signal compatibility: thermocouple, thermal resistance, resistance, millivolt, voltage, 4–20mA, sliding position transmitter.
- Point-to-point 400VDC isolation, 1000VDC isolation between channels and between the controller logic bus.
- Synchronous A/D conversion with the CPU, eliminating data transmission delay, and parallel multi-module processing.
- 15 high-resolution A/D converters, with all input channels having a fixed global update rate of 500ms.
- Strong noise suppression: Under 120VAC industrial interference, the series mode exceeds 60dB, and the common mode exceeds 130dB.
- All thermocouple inputs are equipped with built-in cold junction compensation.
- Multi-state diagnostic LED indicator: Green light flashing = Normal scan, Amber light flashing = Forced channel signal, Red = Module failure alarm.
- Each channel can be customized with a fault protection value, which is used in cases where abnormal signals are lost.
- Pre-warning of thermocouple sensor failure and complete circuit break detection.
- Non-volatile memory stores factory calibration, on-site calibration and channel configuration data.
- Long-term stability: The maximum full-scale drift per year is 0.1%. The factory accuracy is ±0.1% of the measurement range.

In-Field Notes：
- Based on on-site debugging experience, the point-to-point isolation design effectively eliminates the common grounding loop noise problem in multi-sensor wiring environments, which is particularly important for low-level millivolt-level thermocouple signals.
- When connecting the 4–20mA transmitter, the built-in 24V loop power supply and the onboard 250Ω current-sensing resistor simplify the on-site wiring, eliminating the need for additional external signal conditioning hardware.

Discussion on "How to choose the right industrial power supply for a server rack"
Almost all control cabinets require a DC power supply. Some control cabinets only use alternating current for motor control, but except for these exceptions, control cabinets also require direct current power to supply power to PLCS, Hmis, digital and analog I/O devices, relays and contactor coils. It is precisely the responsibility of industrial power supplies to provide these DC power sources.
