Description
⚙️ The GE IS210DTURH1A / IS210DTURH1AA is a DIN-rail-mounted DTUR Pulse Rate Terminal Board used in the GE Mark VI turbine control system. The DTUR provides four pulse-rate inputs from passive magnetic speed sensors and interfaces with the VTUR processor board. The board is designed for speed and flow measurement, with a typical pulse-frequency range of 2–14 kHz. It uses two Sub-D connectors, 15-pin and 37-pin, for connection to the associated VTUR circuitry, together with a 36-terminal field wiring block.
