Product Description
Promoted as a DIN-Rail Mounted RTD Terminal Board the IS210DRTDH1AA model is specifically designed to function as a compact terminal board to be used with resistance temperance detector functions. During the operation of the DRTD board, it will be connected to the VRTD processor board through a single thirty-seven-pin cable connector. This connector is identical to the one on the TRTD board which can also connect to a VRTD processor board. When the model has been mounted in a cabinet-type application up to two DRTD boards can be stacked vertically to conserve cabinet space.
The main components of the IS210DRTDH1AA board are the sub-D connector, the eight RTD inputs, and the Euro block type terminal block. The composition of the Euro terminal block is thirty-six terminals. Please note that terminals twenty-five through thirty-four are described as spare terminals. The Euro block cannot be removed from the DRTD board and is permanently attached to the board. The bottom two screws on the Euro block are used for the ground or SCOM connection.
There are specific wirings that are needed when connecting and wiring the IS210DRTDH1AA board to other models the wiring will be shielded twisted triplet wires, these wires are also known as #18 AWG wires.
Typically termination models are described as either a termination barrier or a termination block, due to the composition of the board it can be assumed that the IS210DRTDH1AA model is a termination block type model. All of the above information regarding how the DRTD model is installed and the operation can be obtained from the GEH-6421C Volume II Mark VI System Guide which is attached to this page under the manuals tab.
