FUNCTIONAL DESCRIPTION:

DS200CTBAG1ADD is a C-Core Analog Termination Module manufactured and designed by General Electric as part of the Mark V LM Series used in Aeroderivative Control Systems. The Termination Module (CTBA) terminal board is located in the core. The CTBA terminal board lands the 4–20 mA output signals, the 4–20 mA input signals, and the shaft voltage and shaft current signals. The IONET connection to the STCA board and the COREBUS connection to the QTBA board on the core are also located on the CTBA board. The 24 V DC power for diagnostics comes from the TCPD board in the core. A bypass relay that allows the COREBUS to continue to communicate if power is lost to the CTBA terminal board is located on the CTBA terminal board.

CTBA CONNECTIONS:

8PL – Carries the IONET signals to the STCA board in the core.
JAA – Carries the 4–20 mA outputs from the TCCA board in the core.
JAI – Used for the COREBUS connection; if not used, then a termination resistor should be attached.
JAJ – Used for the COREBUS connection; if not used, then a termination resistor should be attached.
JBB – Carries 4–20 mA inputs and the shaft voltage and current signals to the TCCA board in the core.
JEE – Communicates the COREBUS signals with the STCA board in the core.
JPD – Carries the 24V DC power signal from the TCPD board in the core.
JX – Communicates the IONET signals with the TCDA board in the core.

FREQUENTLY ASKED QUESTIONS:

What is a C-Core Analog Termination Module?

A C-Core Analog Termination Module is an interface device used to connect analog field signals (such as 4- 20mA or 0- 10V) to control system I/O modules. It ensures proper termination, signal conditioning, and isolation for reliable data acquisition.

What types of analog signals are supported by the module?

The module typically supports industrial standard analog signals such as 4–20 mA current loops, 0–10 V voltage levels, and sometimes ±10 V differential inputs. These are commonly used for sensor outputs and actuator control in DCS and PLC-based systems.

What is the difference between an Analog Termination Module and an I/O module?

An Analog Termination Module is a passive device used for connecting and organizing analog signal wiring, while an I/O module is an active component that converts these analog signals to a digital format for processing by a controller.
