FUNCTIONAL DESCRIPTION:

DS200TCPDG1BCC is a Power Distribution Module manufactured and designed by General Electric as part of the Mark V LM Series used in GE Linear Microprocessor Control Systems. The Power Distribution Module (TCPD), located in the core, distributes the 125 V dc power to the TCPS boards in each I/O core, the Control Engine core, , and the TCEA boards in core. The TCPD board provides switches for powering down each core individually. The digital I/O cores ( and ) do not receive their power from the core, these cores get their power from their associated I/O core and respectively. The DTBA, DTBC, and DTBD terminal boards on both the and cores get their power for the solenoids and wetted contact inputs directly from the TCPD board. The 120/240 V ac for the ignition transformers is supplied by the TCPD board. The CTBA terminal board in the core gets its 5 V power from the TCPD board.

TCPD CONNECTORS:

J7X – Distributes the 125 V dc power to the TCEA board in location one ,, in the core.
J7Y – Distributes the 125 V dc power to the TCEA board in location three, , in the core.
J7Z – Distributes the 125 V dc power to the TCEA board in location five, , in the core.
J8A – Distributes the 125 V dc power to the DTBC board in the core for the solenoids.
J8B – Distributes the 125 V dc power to the DTBD board in the core for the solenoids.
J8C – Distributes the 125 V dc power to the DTBC board in the core for the solenoids.
J8D – Distributes the 125 V dc power to the DTBD board in the core for the solenoids.
J12A – Distributes the 125 V dc power to the DTBA board in the core for the wetted contact inputs.
J12B – Distributes the 125 V dc power to the DTBA board in the core for the wetted contact inputs.
JPD – Distributes 5 V dc power to the CTBA board in the core to be sent to the STCA board in the core for the AC and DC power monitoring signals.
JZ1 – Connection for the TCEA boards and contact input power to drop across the external resistors.
JZ2 – Incoming AC from the TB1 terminal board connected through JZ2 to the DACA, (AC to DC converter), via the JZ connector in the DACA box. Used for AC to DC conversion.
JZ3 – Alternate for JZ2 if the reduced voltage is needed for a special contact output circuit (contact output #18 on the DTBC board of the ).
JZ4 – Auxiliary AC source connection point for applications that require an isolated input for an uninterruptible power source connection(s) and/or switched backup power source. Typically used for a Black Start Inverter.
JZ5 – Standard AC power source connection for the ignition transformers.

TCPD CONFIGURATION:

HARDWARE: The BJS hardware jumper is supplied for isolation of the ground reference on systems with an external reference. When the jumper is in, the ground reference is provided for the external reference systems. Refer to Appendix A and the hardware jumper screen on the operator interface for information on the hardware jumper settings for this board.

TCPD SWITCHES:

The TCPD board has several switches associated with it. Each switch toggles on and off the power for the particular core or board associated with it.

SW1 – Toggles power in the core.
SW2 – Toggles power in the core.
SW3 – Toggles power in the core.
SW4 – Toggles power in the core.
SW5 – Toggles power in the core.
SW6 – Toggles power on in the core.
SW7 – Toggles power on in the core.
SW8 – Toggles power on in the core.

TCPD POWER:

External 115/230 V ac power is brought in via the TB1 terminal board mounted on the core and is hard wired to the TCPD board. The AC power is converted to the 125 DC voltage by being passed through a DACA (AC to DC) block via the JZ2 connector. These signals are then sent to the various cores and boards via the connectors listed above. An optional JZ3 connection is available for applications requiring reduced voltages for contact #18 on the DTBC board in the core. The power distributed to the TCEA boards in the core is additionally conditioned across resistors via the JZ1 connector. The JZ5 connector is used to connect the AC power to the ignition transformer signals in the core.
