IS200SCLTH1AAB is a Core Analog Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Gas Turbine Control Systems. The Core Analog (SCLT) terminal board provides additional I/O terminals for the PCLA module. It handles input signals fanned to one or three PCLA modules and the voted output signals. Inputs include eight thermocouple inputs, four analog voltage or current inputs, and six 4-20 mA outputs. An individual 24 V dc power source is included for all 4-20 mA inputs on SCLT. Forty-eight pluggable Euro-style box-type terminal blocks provide field wire terminal points. The following table lists I/O supported by SCLT:


An I/O cable shield terminal is provided adjacent to the terminal blocks. Field device I/O is through 72 Euro-style box-type terminal blocks on the SCLS side and is through 48 Euro-style box terminals on the SCLT side. SCLS and SCLT accept conductors with the following characteristics.


SCLT provides fanning of input signals to one or more PCLA modules. This is done with high-reliability passive circuits to ensure reliability in redundant applications. SCLT accepts 28 V dc power from connected PCLA modules. The power supplies from all PCLAs are connected through diodes (Diode-OR) to obtain redundant power input for the 24 V dc outputs. Each 24 V output on SCLT is provided with an individual voltage regulator that includes thermal shutdown for branch circuit protection. The SCLT terminal board provides the customer terminals and 68-pin connectors for the SCLS terminal board cable. Forty-eight pluggable Euro-style box-type terminal blocks provide Field wire terminal points.


SCLT can accommodate four simplex / Printed analog voltage or current inputs. They can be located up to 300 m (984 ft) from the turbine control cabinet with a maximum two-way cable resistance of 15 Ω. Connect the input and output wires directly to two I/O terminal blocks mounted on the terminal board. Each block is held down with two screws. A shield terminal attachment point is located adjacent to each terminal block. SCLT can accommodate the following analog I/O types:

  • Analog input, two-wire transmitter
  • Analog input, three-wire transmitter
  • Analog input, four-wire transmitter
  • Analog input, externally powered transmitter
  • Analog input, voltage ±5 V dc, ±10 V dc, current 4-20 mA
