It provides field contact input monitoring and relay output interfaces between external equipment and the excitation controller. Designed for simplex operation, the board handles trip contacts, general-purpose relay outputs, and auxiliary contact signals using separate relay control and contact wetting voltages.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFunctional Description\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe ECTB provides electrical interfaces for contact signals associated with generator excitation control. Its relay outputs allow the controller to operate external circuits, while its contact input circuits monitor the status of customer-supplied auxiliary contacts.\u003c\/p\u003e\n\u003cp\u003eThe board includes two trip relay outputs and four general-purpose Form-C relay outputs. The latter provide normally open, normally closed, and common terminals for external circuit switching. Relay operation is controlled by the excitation controller through the EMIO interface.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eContact Input and Relay Configuration\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe contact input circuits use a nominal 70 V DC wetting supply to detect external contact states. This arrangement allows the controller to monitor auxiliary contacts and dedicated generator status and lockout signals.\u003c\/p\u003e\n\u003cp\u003eThe distinction between the board's voltage ratings is important: \u003cstrong\u003e24 V DC\u003c\/strong\u003e supplies the relay control circuits, \u003cstrong\u003e125 V DC\u003c\/strong\u003e is the nominal customer supply for relay contacts, and \u003cstrong\u003e70 V DC\u003c\/strong\u003e provides contact wetting for input monitoring.

The ECTBG1 version is used for redundant control and has a different controller interface and relay voting arrangement.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between the 24 V DC and 125 V DC supplies?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: The 24 V DC supply operates the relay control circuits, while the nominal 125 V DC customer supply is switched through the relay contacts to external circuits. They perform different electrical functions and should not be interchanged.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the purpose of the 70 V DC wetting voltage?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA: It provides the electrical excitation required to monitor external contact states.
