WBo2 2DP Prebuilt Pro. Wideband

              From March 2011.

The 2DP is Tech Edge's professional quality pre-built wideband product for Bosch LSU (5 wire) sensors. It is based on the SMD 2D1 OEM unit.

2DP is designed for applications that require a fully operational professional unit ready-to-go. It comes in a diecast and water resistant case and has options for a number of interfaces including 4-20mA and 0-5 Volt wideband Lambda and percentage oxygen.

Connection Overview for 2DP

The image at right shows how 2DP is connected to other wideband components to make a usable system. Each component (clockwise from top left) is described below:

  • A standard 8-pin circular connector is used to connect to a standard Tech Edge controller-to-sensor cable which is available in various standard length.

  • Two Bosch sensor families are supported - the newer LSU-4.9 and the older LSU-4.2 sensor.

  • A DB-15 (male) connector (top right) provides optional I/O and includes the 4-20 mA current loop output and user inputs. It also carries a connection for the autocal button.

  • A DB-9 (female) provides an RS232 connection to a PC or other logging or display device. To use a standard Tech Edge display, a special DB9-to-RJ45 display-adaptor is required (this is shown far right).

  • A 5-pin circular connector carries the power/GROUND input and the wideband output (WBlin+/WBlin-) and also an (optional) RPM input.

  • Between the two circular connector is a 3-Amp fuse.

Dimensions: The diecast case itself is 120x100x36 but the connectors at each end add a further few tens of mm.

The following sections are being updated (25 Feb 2011)

We hope to have a complete description of the 2DP controller available by Mar 01 2011. Note that as of December 2010 Tech Edge has already sold a number of these controllers to various businesses that needed a solution matching 2DP's capabilities.
