PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1771-KE is a PLC-5 communication controller module designed for rack installation. It provides interface connectivity for Data Highway networks and RS-232-C serial communication channels. The unit mounts into a compatible 1771 rack chassis without needing external operating power. It draws an operating power requirement of 1.2 amperes at 5 volts DC. The backplane current consumption is rated at 750 milliamperes.
This module includes a processor port operating at a transmission speed of 91.2 kilobaud. Circuit assemblies feature a conformal coat for enhanced protection in demanding industrial settings. Field wiring connects through a 1771-WH wiring arm mounted to the rack assembly. The total physical weight of this controller module is 2.81 pounds.
