GE DS200TCDAH1 Mark V Digital I/O Board

DS200TCDAH1 processes digital contact inputs from DTBA and DTBB and contact-output signals associated with TCRA. It communicates the digital I/O data through the Mark V IONET connection.

DS200TCDAH1 receives contact input signals from DTBA through JQ and from DTBB through JR. The board conditions the signals and time-tags changes in their state.

DS200TCDAH1 uses the JX1/JX2 connections for the IONET signal path. The network carries the processed digital I/O information between TCDA and the associated Mark V I/O electronics.

DS200TCDAH1 uses JO1 and JO2 for the contact-output paths to the TCRA relay boards. The TCRA interfaces provide the relay/solenoid output connections used by the installed control application.

DS200TCDAH1 uses J4, J5 and J6 for the hardware IONET identity. J2 and J3 are the separate termination-resistor jumpers, so address selection and network termination are distinct settings.

DS200TCDAH1 uses the installed I/O configuration constants for contact-input inversion. Hardware signal conditioning and time tagging remain functions of TCDA; the configured logical interpretation is managed in the system I/O settings.
