SDI-12 Interfaces

SDI-12 Interfaces

WaterLOG SDi-12 Interfaces provide an easy solution to combine the advantages of SDI-12 with other output options. With multiple options to choose from, WaterLOG is the industry leader in providing SDI-12 interfaces. See our interface options below.

  • Interface Options

H-4161 SDI-12 to 4-20mA Interface
Designed for easy data viewing, The H-4161 SDI-12 to 4-20mA Interface has a built-in LCD display which shows the current SDI-12 data of the attached sensor. This interface allows any SDI-12 sensor to be connected to a PLC, RTU, or other device that reads 4-20mA signals.
H-423 SDI-12 to RS-485 Interface

Ideal for systems that need more length, the H-423 SDI-12 to RS--485 Interface extends the distance between the SDI-12 sensor and SDI-12 recorder. Two units are required—one at each end.

H-4191 RS-232 to SDI-12 Interface

The H-4191 RS-232 to SDI-12 Interface provides a link between an SDI-12 sensor and computer (or other device that requires an RS-232 connection).

H-4280 8-channel Anaglog to SDI-12 Interface

Designed to increase the number of analog sensors connected to an SDI-12 data logger, the H-4280 8-channel Analog to SDI-12 Interface converts analog signals to SDI-12 signals for any SDI-12 recorder. It also supports 0-5v and ±5V operations.
H-4501 SDI-12 to Fiberoptic Interface

Ideal for applications with severe interference caused by heavy electrical equipment or radio communication, the H-4501 SDI-12 to FIberoptic Interface allows SDI-12 communications to be extended to very long distances with a fiber optic link.
