Features:
- RS-232-C device access to Data Highway Plus
- 1771 I/O rack installation with 5 V backplane power
- Separate DH+, terminal, and asynchronous serial connections
Allen-Bradley 1785-KE acts as the boundary between a programmable serial device and a legacy Data Highway Plus network.
Its three connector roles keep the DH+ dropline, 1784-T50 terminal access, and asynchronous RS-232-C device interface distinct during wiring and troubleshooting.
A dependable installation depends on the correct terminal-or-modem cable, Belden 9463 DH+ cabling, available rack current, and matched serial communication settings.
Apter Power can review 1785-KE Series, rack, serial-device role, and cable requirements before quotation.
