Product Description
DS200RTBAG2AFB is a relay terminal board (RTBA) designed for General Electric’s Mark V board series
. This board can be used in applications across several GE brand drives and exciters. By installing this bo
ard into a drive cabinet, an additional ten relays are provided to the user. Both the LAN I/O terminal and a r
emote user can drive the relays found on this board.
Locations K20 through K29 are the board positions for all onboard relays. DS200RTBAG2AFB includes tw
o types of relays, DPDT and 4PDT. DPDT type comprises seven of the relays found on the card, including K
20 through K26. These types feature two Form C contacts, with each contact rating 10A. K27 through K29 i
s the second relay type, 4PDT. Rather than two, 4PDT relays include four Form C contacts that each rate 1A
. All ten of these points are protected by a 130 VAC metal oxide varistor (MOV). Each relay contains an intern
al 110 VDC coil that ensures they are operating properly. Should any relay stop functioning or break, the use
r can easily remove and replace all ten spots.
There are two connectors used with the DS200RTBAG2AFB model; one is a sixteen-pin connector, with the other is a two-pin connector. The sixteen-pin connector is labeled as RPL and the two-pin connector is labeled as OPTPL. The OPTPL connector has two nomenclatures X2 and CFX1. The X2 nomenclature will send signals back to the NTB/3TB board of the CFX1 nomenclature 120 VAC loads. This nomenclature is identical to the RPL X2 nomenclature. For all nomenclatures available with the two connectors refer to Tables 3 and 4 in the GEI-10016B manual.
Frequently Asked Questions about DS200RTBAG2AFB
Is every pin in the sixteen-pin (RPL) connector connected when used on the DS200RTBAG2AFB model?
No. The pins that are consistently connected on the RPL connector are pins 1, 3, 5, 7, 9, 11, 13, and 15. Each of the pins has an individual nomenclature as well as an individual description. For example, pin 13 is known as the RX6 nomenclature. The RX6 nomenclature is described as the pilot input from the LTB for relay K25 on the RTBA model. For other nomenclatures and descriptions refer to Table 3 in the GEI-100167B Manual on page five.
How many terminal points are available on the DS200RTBAG2AFB model?
There are fifty-two terminal points available on the DS200RTBAG2AFB model. Each of the terminal points has its own nomenclature and description. One example of nomenclature and description is terminal point twenty-seven. The nomenclature on terminal twenty-seven is K232CM, with a description relaying K23 Form C contact number two. For more information on all of the nomenclatures, terminal points, and descriptions, refer to the GEI-100167 manual.
This RTBA board has two stab connectors on its surface. This includes the CPH stab connector used for the pluggable circuit control power, the positive side, as well as the CPN stab connector is used for the circuit control power negative side. This is also a pluggable circuit.
