GE IS230TPROH2C
Product Name: GE Mark VI / Mark VIe TPRO Analog I/O Terminal Board
Product Introduction: The GE IS230TPROH2C is a passive signal-conditioning and termination board belonging to the VPRO (Vibration Protection and Overspeed) family, used to scale LVDT, thermocouple, and 4–20 mA signals for the turbine protection processor.
Detailed content
Technical Specifications:
-
Signal Types: LVDT, TC (Type J/K/E), 4–20 mA, ±10 V
-
Channels: Configurable per terminal block
-
Isolation: Galvanic barrier between field and controller
-
Mounting: Panel-mounted terminal board, wired to VME/PACK I/O
-
Operating Temp: -30 °C to +65 °CFunctional Features: No active processing—pure signal scaling and buffering; supports VPRO independent overspeed protection; brings generator voltage, bus voltage, and speed-pickup wiring to protected side.Materials & Structure: FR-4 base, barrier terminal blocks, screw-clamp copper alloy terminals, no onboard firmware.Working Principle: Field sensors terminate on the outer row; internal precision resistors and jumpers scale signal to controller ADC range; shield drains to chassis ground.Installation Requirements: Mount inside turbine control cubicle; separate signal and power cable trays; use shielded twisted pair for TC/LVDT.Precautions: No software config—faults come from loose lugs or wrong jumper; torque terminals to GE spec; keep away from high-current feeders.
