          PRODUCT DESCRIPTION

          1784-KT/B Series B ISA Communication Interface Card

          Allen-Bradley 1784-KT/B is the customer-specified model notation for the manufacturer's 1784-KT/B Series B communication interface module. The half-length eight-bit ISA card connects a compatible host computer to Allen-Bradley controllers through a direct serial connection or Data Highway Plus. A sixty-two-pin D-shell connector carries the documented external interface.

          The official Series B installation data specify 57.6 kbit/s synchronous DH+ operation and 9600 or 19200 baud asynchronous PLC-2/PLC-3 connections. The host memory address and hardware interrupt are selectable; the factory arrangement is D400 with no interrupt selected. Power demand is 0.4 A at 5 V and 0.04 A at 12 V. The permitted operating ambient is 0 to 55 degrees C with 5 to 95% noncondensing humidity.

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate 1784-KT/B within Allen-Bradley 1784-KT

          Install the Series B card only in a compatible ISA host supporting the documented eight-bit interface; an eight-bit or sixteen-bit ISA slot may be used. Reserve the selected shared-memory area and hardware interrupt without conflict with other host cards. The factory D400/no-interrupt arrangement must be checked against the actual computer.
          Choose the documented cable for direct PLC-2/PLC-3 access or the DH+ arrangement. The sixty-two-pin D-shell connector does not itself define the far-end pin assignment. Keep the 9600/19200-baud serial settings distinct from the 57.6 kbit/s DH+ network setting.
          Install the compatible host driver and application software, then run the interface diagnostics before connecting normal application traffic. Include the 5 V and 12 V host demands in the expansion-slot budget. Maintain the specified temperature and noncondensing-humidity conditions for the host installation.

          Features:

          • Host expansion bus: ISA; 8-bit half-length card
          • Compatible expansion slots: 8-bit or 16-bit ISA
          • Allen-Bradley 1784-KT
          Use 1784-KT/B only within the documented Allen-Bradley 1784-KT arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 1784-KT/B within Allen-Bradley 1784-KT

          Record the complete 1784-KT/B identity, the manufacturer 1784-KT/B marking, switch settings, selected IRQ and host-driver configuration. Preserve the Series B distinction. A 1784-KTX or KTXD card is a separate model and must not inherit settings solely because the connector or board appearance is similar.
          Power down the computer and disconnect its AC feeder before opening the expansion-slot area. Use the prescribed ESD precautions and label the external cable. Compare the replacement memory-address and interrupt settings with the saved host configuration before insertion.
          After installation, run the supported diagnostics and verify the driver sees the selected memory and IRQ arrangement. Test the intended direct controller or DH+ connection using the correct cable and rate. Restore normal application traffic only after communication checks pass.

          Features:

          • 1784-KT/B complete order code
          • Published DH+ segment limit: 3050 m at 57.6 kbit/s
          • Retain the documented Allen-Bradley 1784-KT connection arrangement
          Use 1784-KT/B only within the documented Allen-Bradley 1784-KT arrangement and applicable installation instructions.
