PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-HT is an SLC 500 termination panel. It provides field wiring termination for motion control signals. The unit occupies 1 rack slot. It interfaces with the IMC 110 motion controller. Rated input frequency reaches 250 kilohertz. Digital outputs provide fast signaling with verified step response. Step response is 100 milliseconds in and 2.5 milliseconds out. Backplane current consumption is 200 milliamps at 5 Volts. Current at 24 Volts is 90 milliamps.
The panel supports single-axis encoder feedback for linear or rotary axes. Built-in LED indicators show the status of each fast input and output point. External power connections distribute plus 5, plus 15, minus 15, and plus 24 Volts. The unit includes dedicated emergency stop and drive enable circuits. Field wiring connects using a screwdriver and a wire stripper. Users can mount the panel on DIN rail up to 2.1 meters from the controller.
