Product Description

The Simplex DIN-railed Mounted Trip Transition Board IS200DTRTH1ABA is used to interface to the VTUR board alongside the DRLY board. This model also permits up to six trip functions on the VTUR board which will interface with the DRLY model rather than the TRPG module. With some of the connectors on the DTRT board, there is the possibility for up to two VTUR boards to be connected. If two VTUR boards have been connected to the DTRT board there is the possibility for the VTUR boards to control six relays. 

For every application in which a trip system between the DRLY and VTUR model is used the IS200DTRTH1ABA model must also be used. Note that if only one VTUR model is required under no circumstances can the DTRT be eliminated. 

The main components of the DTRT board are three thirty-seven-pin D-type connectors. The two connectors labeled J1 and J2 are used to cable from the two VTUR boards, and the J3 connector is used to connect to the DRLY board which has six relay circuits. On the right edge of the IS200DTRTH1ABA board, there are three screws labeled TB1. The TB1 screws are used for ground (SCOM) connection. 

While there are several other redundancy types that can be used with Mark VI models the DTRT board can only be used with a simplex redundancy type. Please note that this model is known as a termination box board that has a plastic mounting holder to allow for the model to be mounted in a DIN-rail capacity.
