Q1: What is the primary function of the 20BC085A0AYNANC0?
It is a PowerFlex 700 adjustable frequency AC drive used to control the speed and torque of three-phase AC motors. It is designed for medium-power industrial applications requiring precise motor control, with vector control capability and an integrated brake IGBT for dynamic braking .
Q2: Is this drive still in production?
No. The PowerFlex 700 series was discontinued by Rockwell Automation as of November 30, 2023 . It is now available through aftermarket suppliers, surplus stock, and refurbished units. The recommended replacement is the PowerFlex 755 family .
Q3: Does this drive include a Human Interface Module (HIM)?
No. The model number includes "No HIM - Blank Plate", meaning it ships with a blank cover instead of an operator interface . For local programming and monitoring, a compatible HIM (such as 20-HIM-A6 or 20-HIM-C6S) must be ordered separately.
Q4: What communication options does this drive support?
The drive has no factory-installed communication module but supports optional DPI communication modules for EtherNet/IP, ControlNet, DeviceNet, and PROFIBUS DP . It also has a standard RS-485 interface for basic serial communication.
Q5: What is the difference between the 20BC085A0AYNANC0 and the 20BD085A0AYNANC0?
The primary difference is the voltage rating. The 20BC prefix indicates 400 VAC input, while the 20BD prefix indicates 480 VAC input . Both are PowerFlex 700 series drives with the same 85 A current rating and similar power capabilities, but they are designed for different supply voltage systems.
The Allen-Bradley 1794-OE4 is a 4-channel analog output module for the FLEX I/O system. It provides 4 single-ended, non-isolated outputs with software-selectable voltage (±10V, 0–10V) or current (0–20 mA, 4–20 mA) ranges, offering 12-bit plus sign resolution and 1.024 ms conversion rate for all channels.
The Allen-Bradley 1794-IRT8 is an 8-channel thermocouple, RTD, and millivolt input module for the FLEX I/O system. The module features 14-bit input resolution, wire-off/overrange/underrange detection, and cold-junction compensation via external compensators (1794-CJC2) for thermocouple accuracy.
The Allen-Bradley 1794-OF4I is a 4-channel isolated analog output module for the FLEX I/O system. The module supports Removal and Insertion Under Power (RIUP) for hot-swap maintenance and includes open-wire detection and field power monitoring diagnostics.
The Allen-Bradley 1794-IF8IH is an 8-channel isolated HART analog input module for the FLEX I/O system. It provides 8 individually isolated current inputs (0–20 mA or 4–20 mA) with 16-bit resolution and HART 5/6/7 pass-through communication, enabling remote configuration, calibration, and diagnostics of HART-enabled transmitters without additional multiplexers.
The Allen-Bradley 1794-OE8H is an 8-channel HART analog output module for the FLEX I/O system, designed for process control applications requiring direct communication with smart field devices. It provides 0–20 mA or 4–20 mA current outputs on each channel while simultaneously enabling HART digital communication over the same two wires, eliminating the need for external HART multiplexers or additional wiring.
The Allen-Bradley 1794-IT8 is an 8-channel thermocouple/millivolt input module for the FLEX I/O system, designed for direct interfacing with a wide variety of thermocouple sensors and low-level millivolt sources. The module includes cold-junction compensation and on-board scaling, simplifying programming and eliminating the need to scale data in the user program.
The Allen-Bradley 2711P-RDB10C is a PanelView Plus 1000 series display module designed as a replacement or spare for PanelView Plus and PanelView Plus 6 1000 operator terminals. It features a 10.4-inch color TFT display with 640 x 480 pixel resolution, a keypad and analog resistive touchscreen for operator input, and a CCFL backlight rated for 50,000 hours.
The Allen-Bradley 20G1F3D960LNDNNNNN is a PowerFlex 755TR regenerative AC drive with TotalFORCE control technology, designed for high-power industrial applications requiring energy regeneration and harmonic mitigation. Operating at 480 VAC, 3-phase, it delivers 800 HP (600 kW) normal duty with a rated output current of 960 A in a Frame 9 design.
