【英文介绍】

The Digital I/O Terminal Unit (TDI) is INFI's interface ®90 process management system I/O signal. It provides a physical connection point for process site wiring, as well as configuration to receive system I/O signals. This note describes the purpose, characteristics and details of the end unit's tions. It details the process to follow to set up and install the terminal unit and explains maintenance Nance and replacement procedures. System engineers or technicians working with TDI should read and understand this instruction prior to installation and configuration - Use the terminal unit. In addition, the position of a complete INFI 90 system is beneficial to users.

Hardware description Feature Versatility Adaptability to reliable system protection Minor repair Hardware Description 1-2TDI is an end panel (NFTP01) in the INFI 90 cabinet that is connected to a single printed circuit board. Two screws and spacers hold the TDI in place. Up to 16 indi-vidual I/O signals can be connected to the TDI. The printed cir-CUIT board consists of the following parts: 1. A 16-point configuration socket (XU1 to XU16) is used to connect and draw each I/O signal. 2. Four terminals (TB1 to TB4) provide connection points for physical I/O signals. 3. Terminal cable socket (P1) connecting the terminal - connecting the 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 points) for system power configuration tions. 5. Two onboard fuses (F1 and F2) are used to protect the E1/E2 power supply connected to the end unit's power supply and field equipment. 6. The terminal unit is configured with XU17 to configure the TDI signal route, which is suitable for some applications. TDI is designed so that 90 modules can be used with a variety of INFIs. It can be used to input digital or analog signals to INFI 90 systems, or to output digital or analog signals to field devices. These signals provide control and monitoring capabilities. Contact with the system. 16 individual I/O signals can be connected to the TDI. These signals can be configured according to process requirements. The shunt on the end unit configures each I/O channel. Each channel can be configured as either a system power signal or a field power signal. TDI is a passive component and has no active component installed on its board; It does not require a power source to operate. This makes the end unit less prone to failure. The fuse power input protects the INFI 90 module circuits and professional CESS field equipment. TDI does not have any special maintenance requirements other than the routine maintenance defined in this section.
