Product Details
HARDWARE DESCRIPTION
A TDI is a single printed circuit board that attaches to a Field Termination Panel (NFTP01) inside an INFI 90 cabinet. Two screws and spacers secure the TDI in place. Up to sixteen individual I/O signals can be connected to the TDI. The printed circuit board consists of:
| 1. Sixteen point configuration sockets (XU1 to XU16) to configure each I/O signal. | |||
| 2. Four terminal blocks (TB1 to TB4) that provide the physical connection points for I/O signals. | |||
| 3. A termination cable socket (P1) that connects the termination unit to its slave or master module. | |||
| 4. I/O power (24 VDC, 125 VDC or 120 VAC) connection points (E1, E2 and E3 common) for system powered configurations. | |||
| 5. Two on-board fuses (F1 and F2) to protect the E1/E2 power supplies and field devices connected to the termination unit | |||
| 6. A termination unit configuration socket (XU17) to configure TDI signal routing for some applications. |
Products Description
-
Versatile
The design of the TDI allows it to be used with a variety of INFI 90 modules. It can be used to input digital or analog signals to the INFI 90 system, or output digital or analog signals to field devices. These signals provide control and monitoring capabilities to the system.
-
Adaptable
Sixteen individual I/O signals can be connected to the TDI. These signals can be configured according to the process requirements. Dipshunts on the termination unit configure each I/O channel. Each channel can be configured as a system powered signal or field powered signal.
-
Reliable
The TDI is a passive assembly with no active components mounted on its circuit board; it does not require power to operate. This makes the termination unit less susceptible to failure.
