GE 151X1215DC20SA01 I/O Terminal Board

Product Brief Description

GE 151X1215DC20SA01 is a signal terminal board designed for GE legacy turbine control systems. It serves as the physical wiring interface between the I/O control modules and field devices, supporting the distribution of analog and discrete signals. The PCB is coated with conformal coating to resist moisture, dust and corrosive atmosphere in power plant cabinets, widely used for overhaul, spare replacement and retrofitting of old gas and steam turbine control units.

Product Functions

• Provide terminal blocks for connecting field sensors, switches and actuators to I/O cards
• Route and distribute analog measurement signals and discrete interlock/trip signals
• Built-in surge suppression components to protect back-end I/O circuits from transient damage
• Convenient for on-site signal testing, circuit isolation and troubleshooting during commissioning
• Conformal coated circuit board for reliable long-term operation in harsh cabinet environments
• Transmit safety interlock and protection signals required for turbine control logic
• Onboard status LEDs to quickly identify wiring and signal faults
• Standard rack mounting structure for installation inside turbine control cabinets

Application Scenarios

• Legacy GE gas turbine and steam turbine control cabinets
• Power plant combined cycle unit protection and interlock control loops
• Refineries, petrochemical and chemical captive power turbine equipment
• Old turbine control system overhaul, spare stocking and cabinet upgrade projects
• Compressor drive turbine auxiliary signal acquisition and output circuits
• Industrial power generation obsolete control component replacement
