About the IS210DTURH1AA
The IS210DTURH1AA board is described in the GEH-6421C Volume II System Guide for the Speedtronic Mark VI Turbine Control System Guide as a compact pulse-rate terminal board that only has simplex application and is DIN-rail mounted. Four magnetic pickups, or pulse-rate transducers, are used for measuring speed and flow. The primary I/O processor board that the DTUR uses is the VTUR board; please note that when connecting the DTUR board up to two models can potentially be connected to the VTUR model.
IS210DTURH1AA Part Number Insights
This Simplex DIN-rail Mounted Pulse Rate Terminal Board's two significant revisions were only made apparent upon an analysis of the IS210DTURH1AA functional product number, which was necessitated due to this IS210DTURH1AA device's lack of online-available originally-printed instructional manual materials. With this lack being identified, this IS210DTURH1AA functional product number can serve as a primary source of IS210DTURH1AA Board hardware details, including this IS210DTURH1AA product's:
- DTUR functional product abbreviation
- Conformal PCB coating style
- Group one Mark VI Series product grouping
- Two-fold revision history
Additional IS210DTURH1AA Hardware Specs
The DTUR model is described as a termination box and is closely related to the TTUR board which is also used for VTUR I/O termination. The main difference between the DTUR and TTUR models is that the TTUR model has synch relays, two PTs, and two SVMs along with the four pulse rates. There is also a Euro block-type terminal block that is permanently mounted to the board, this block is located on the bottom of the board and has thirty-six terminals. The typical wiring terminal needed is a shielded twisted pairing labeled as #18 AWG. There are also:
- two sub-D pin connectors
- JR5 connector used to cable to the VTUR board
- JR1 with latching fasteners for the J3 connector on the VTUR board
- pulse rate or speed inputs
- used to detect speed on a sixty-toothed wheel
- speed on the wheel should be at zero
- a sensitivity of two Hertz
- typical range being two to fourteen thousand Hertz
