FUNCTIONAL DESCRIPTION:

DS200RTBAG2A is an RTBA Relay Terminal Board manufactured and designed by General Electric as part of the EX2100 Series used in GE Excitation turbine control systems. The DS200RTBAG_A_ _ (RTBA) board is an optional board located within the drive (or exciter) cabinet. The RTBA board provides ten relays that are driven either directly from the pilot relays on the 531X307LTB LAN I/O Terminal Board (LTB) or remotely by the user. Seven of the ten relays have two Form C contacts (DPDT relays) and the other three relays have four Form C contacts (4PDT relays).

RELAY DESCRIPTIONS AND REPLACEMENT:

The ten relays are designated K20 through K29. Relays K20 − K26 are the DPDT type relays and K27 − K29 are the 4PDT type (see Figure 1). Each relay has an LED that indicates when the relay is energized (located at the top of the relay inside the relay’s case). All I/O of the relays is protected by 130 V ac metal oxide varistors (MOVs). Any of the ten relays can be replaced individually if needed.

• Open the drive's cabinet door to access the board. (The RTBA board is typically located below the drive’s board rack.)
• Remove the retaining clip for the relay to be replaced by pressing on the top of the retaining clip and pulling on either side of the clip to release it.
• Remove the old relay by pulling it straight out from the relay socket.
• Orient the new relay on the socket (will only fit one way) and press the relay into the seated position in the socket.
• Replace the retaining clip on the new relay by centering it over the relay and pressing on the top until the bottom of the clip engages on the relay socket.

BOARD CONNECTIONS:

• A 16-pin connector (RPL) and a 2-pin connector (OPTPL) provide RTBA board I/O with the LTBA board. The usage of certain signals of the RPL connector is jumper-selectable.

• Two stab connectors, CPH (control power hot, positive) and CPN (control power negative) are provided to supply control power to certain pluggable circuits. The usage of these stab connectors is jumper selectable. See Table 2 for RTBA board jumper descriptions and Table 5 for the stab connector descriptions.

• The RTBA board provides pluggable circuits and access to relays K27 − K29 through connectors C1PL − C5PL and Y9PL − Y37PL. The control power source for these pluggable circuits is jumper selectable (see Table 2). See Table 6 for the C1PL − C5PL and Y9PL − Y37PL connector descriptions.

FREQUENTLY ASKED QUESTIONS:

What is an RTBA Relay Terminal Board?

The RTBA Relay Terminal Board is an interface board used for signal switching, control, and monitoring in industrial systems. It is commonly used in turbine control, power plants, and automation systems.

What are the voltage and current ratings of the relays?

The relays on an RTBA board generally have a voltage rating of up to 250 V AC/DC and a current rating of 2 A per relay. These ratings make the board suitable for controlling medium-power devices in industrial environments.

What type of contacts are used in the relays?

The relays on an RTBA board typically use Single-Pole Single-Throw (SPST) or Single-Pole Double-Throw (SPDT) contact configurations. The contacts are made from silver alloy or gold-plated materials to ensure high conductivity and durability, even in demanding operating conditions.
