System Architecture & Signal Flow
The DX2048T-3-4-1 installs into a dedicated expansion slot on the DX2048 mainframe rear panel. Field wiring connects directly to the module’s screw-terminal block. The module’s onboard A/D converter digitizes each channel at the mainframe’s configured scan rate. Digitized values are passed via the internal backplane bus to the DX2048 CPU for real-time display, alarm processing, and data logging to internal flash memory or external CF/SD card. Communication to SCADA or DCS systems is handled by the mainframe’s communication module (Ethernet/RS-485 Modbus).

Technical FAQ
Q: Is the DX2048T-3-4-1 compatible with the DX2010 or DX2020 mainframe?
A: No. The DX2048T-3-4-1 is specifically designed for the DX2048 (48-channel) mainframe. For DX2010/DX2020 compatibility, please inquire about the corresponding module variants.
Q: Can this module accept 4–20 mA current loop inputs directly?
A: Yes, with an external 250 Ω shunt resistor converting the current signal to a 1–5 V DC voltage input, which the module measures on its DC voltage range.
Q: What is the maximum number of DX2048T-3-4-1 modules that can be installed in one DX2048?
A: The DX2048 supports up to 12 expansion module slots, allowing a maximum of 48 analog input channels when fully populated with 4-channel modules.
Q: Is a calibration certificate included?
A: Factory calibration data is embedded in the module firmware. A printed calibration certificate can be provided upon request at time of order.
Q: Do you provide installation and commissioning support?
A: Yes. Our engineering team provides remote commissioning guidance and wiring diagram review at no additional charge for qualified orders.
