Specifications taken from the manufacturer datasheet.
Which version do I need?
ATOP's selection guide gives the SE5904D-sdk the same option set as the standard SE5904D: two 10/100 RJ45 ports or two 100/1000 SFP slots, DB9 or terminal block serial connectors, and optional 3 kV isolation. The brochure's SDK table shows a single 'SE5904D SDK' entry with 2 × 10/100 RJ45 and does not print SDK ordering codes for the SFP or isolated builds, so specify these options when ordering. For reference, the standard SE5904D codes are SE5904D-DB, -TB, -SiS, -G-DB-SFP, -G-TB-SFP and -G-Sis-SFP.
Typical applications for the SE5904D-SDK
- Custom data collection from four serial devices in a DIN-rail cabinet
- Edge protocol conversion for multi-drop RS-485 lines
- Fibre-uplinked edge computing in noisy or long-distance sites (SFP version)
- Local alarm signalling through the relay output from your own application
- IIoT gateways pushing serial data to a cloud platform
- Data logging to SD card at remote cabinets

SE5904D-SDK — frequently asked questions
How does the SE5904D-SDK differ from the standard SE5904D?
Both have four RS-232/422/485 ports, two Ethernet ports, one relay output, redundant 12-48 VDC power and a -40°C to +85°C rating. The standard SE5904D ships with ATOP's serial server firmware (TCP modes, VirtualCOM, RSTP, VPN); the SDK version is a Linux development platform with an 800 MHz ARM CPU, up to 512 MB RAM, 128 MB flash, an SD slot, one USB port, watchdog and buzzer.
q
a
Can it use fibre uplinks?
Yes, by version. ATOP's guide lists the SE5904D-sdk with either 2 × 10/100 RJ45 ports or 2 × 100/1000 SFP slots.
What power does it need?
12-48 VDC with redundant inputs, and an optional IEEE 802.3af PoE powered-device input. It also has one relay output.
Which certifications does it carry?
ATOP's selection guide ticks UL 61010-2-201 for the SE5904D-sdk, together with industrial EMC protection, CE/FCC and EN 60950-1 and/or EN 62368.
How does it compare with the SE5901-SDK?
The SE5904D-SDK has four serial ports instead of one, up to 512 MB RAM instead of 256 MB, an SD slot, a relay output, redundant 12-48 VDC power and optional SFP uplinks. The SE5901-SDK has two USB ports to the SE5904D-SDK's one.
