DH-485 Interfaces
DH-485 Interfaces | Cat. No. | Function | Communication Interface | Communication Rates (bit/s) | Current Load | |
| 1784-PKTX, 1784-PKTXD |
PKTx Communication Card | Performs data transmission, management, and local network diagnostics for SLC processors over the DH-485 link. | PKTX: 1 DH+ or Remote I/O and 1 DH-485 port PKTXD: 2 DH+ / 2 remote I/O ports and 1 DH-485 port |
• DH-485: 1200, 2400, 4800, 9600, 19,200 | 0.8 A @ 5V DC |
| 1747-AIC | Isolated Link Coupler | Provides the connection for SLC processors and other DH-485 devices to the DH-485 network. | Shielded twisted-pair | — | • 0.085 A @ 24V DC |
| 1747-UIC | USB to DH-485 Interface Converter | Provides an interface between a computer's universal serial port (USB) and DH-485 ports on SLC500, MicroLogix, CompactLogix, PanelView, AIC and AIC+ products. | 2 ports: • USB • DH-485 (RJ-45 or 9-pin D-shell, switch selectable) |
19200 | Powered by computer's USB port |
| 1746-BAS | BASIC Module | Runs user-written BASIC programs independent of the processor. | 2 peripheral ports configurable for: • RS-422 • RS-485 • RS-232/423 compatible: 1 DH-485 port |
• 300 • 600 • 1200 • 2400 • 4800 • 9600 • 19200 |
• 0.150 A @ 5V DC • 0.040 A @ 24V DC |
| 1747-KE | RS-232-C / DH-485 Interface Module | Chassis-resident module that interfaces the SLC processor to an RS-232 device, like a modem. Communication between the processor and the 1747-KE occurs via a DH-485 network (and not over the backplane). | 3 ports: • 1 DH-485 • 1 DF1 • 1 configuration DF1 and configuration ports accommodate RS-422, RS-485, and RS-232/423 communication configurations |
• DH-485: 1200, 2400, 4800, 9600, and 19200 • DF1 and configuration ports: 300, 600, 1200, 2400, 4800, 9600, and 19200 |
• 0.150 A @ 5V DC • 0.040 A @ 24V DC |
| 1761-NET-AIC | AIC+ Advanced Interface Converter | Provides an interface between a DH-485 link and an RS-232 link. In some configurations, it can be powered from the RS-232 device. | 3 ports: • 2 RS-232 • 1 DH-485 |
• 600 • 1200 • 2400 • 4800 • 9600 • 14400 • 19200 |
• 120 mA @ 24V DC • 200 mA inrush at power turn-on |
| ⋆ Requires a 1747-AIC Link Coupler. | |||||
