TVB3101-1/ISC CPU module

The analog input module does not provide the loop power for the analog input signals. If you interface two-wire transmitters (that require loop power) you will typically need to connect a 24 VDC power source in the input loop to power the transmitter and the input loop. In fault tolerant input applications where redundant analog input modules interface to single sensors, the analog input signals connect in parallel across the redundant input modules. In current input configurations, the three modules connect in parallel across the single external 250 Ohm resistor.

Optional analog input termination blocks can serve as the field wiring termination point for any mode of operation of the analog input board. There are six types of input termination blocks for use with the module. Three are used in single, nontriplicated, analog system configurations. The other three are used in triplicated configurations.

The termination blocks fit on the 10-position barrier strips of the Regent’s I/O chassis without affecting or interfering with the adjacent I/O slot terminals. A 16-position quickterminating Phoenix two-part connector is arranged for easy wiring access. Figure 9 shows one of the two termination blocks provided in a set.

1 8 Industrial Control Services A 1K Ohm resistor isolates the grounding terminal on the input termination block from AGND on the input module, and prevents large currents from flowing through the module because of potential differences in the ground terminal of the upper input termination block with respect to the lower input termination block. The common reference point on the input termination block goes into a separate input pin on the 10-pin barrier strip and in single-ended measurements becomes the common reference for all of the signals on the input termination block. For the non-triplicated module configuration, the three distinctly different types are described below. Termination blocks are available in a set of two termination blocks, one for the upper I/O terminals and one for the lower I/O terminals. These sets are listed below. Voltage Mode Input Termination Block Sets (T3325-V and -VJ) These input termination block sets are used for both singleended and differential voltage measurements. Model T3325-V is used for a single input module. Model T3325-VJ has additional jumper wires to connect the signals to redundant input modules installed in adjacent I/O slots. The proper wiring connections for the voltage mode termination blocks are shown in Figures 10 and 11.
