DS200RTBAG1A is a Relay Terminal Board manufactured and designed by General Electric as part of the EX2000 Series used in Excitation Control Systems. The drive (or exciter) cabinet contains this optional board. Ten relays are provided by the RTBA board, and they can be operated either directly from the pilot relays on the 531X307LTB LAN I/O Terminal Board (LTB) or remotely by the user. The remaining three relays have four Form C contacts, while the remaining seven of the ten relays have two Form C contacts (DPDT relays) (4PDT relays). According to the group number, the three coil voltages for the relays on the RTBA board are as follows:
Fig 1: RTBA Board Layout
The 10 relays are identified as K20–K29. Relays K20 through K26 are of the DPDT type, while K27 through K29 is of the 4PDT type (see Figure 1). The top of each relay, inside the relay's housing, includes an LED that shows when the relay is powered on. Metal oxide varistors with a 130 V ac voltage rating protect each relay's I/O. (MOVs). If necessary, each of the ten relays can be changed separately. The relay part numbers for each RTBA board group number are listed in Table 1.
Table 1: RTBA Board Relay Part Numbers
Berg-type (manually moveable) hardware jumpers on the RTBA board, known by a JP designation, are present and must be properly configured for the application. Most jumper options are pre-set from the factory. The data sheets that come with each controller (found in the drive/exciter door pocket) list these factory default positions.
