Allen-Bradley 1336-L5 42336-173-54 HIM Upgrade Solution

Product Overview

Allen-Bradley 1336-L5 42336-173-54 HIM Upgrade Solution: Seamless Transition from Legacy 1336 PLUS Drives

The Allen-Bradley 1336-L5 42336-173-54 Human Interface Module (HIM) is a critical operator interface component for the 1336 PLUS AC drive series. As Rockwell Automation has progressively phased out legacy 1336 PLUS drive components, many facilities running continuous production lines, HVAC systems, pump stations, and conveyor applications face urgent replacement and upgrade decisions. This listing provides a verified, tested replacement solution for the 1336-L5 42336-173-54 HIM, enabling engineers and maintenance teams to restore drive operability with minimal downtime and zero reprogramming of the host drive.

The 1336-L5 HIM connects directly to the 1336 PLUS drive’s DPI (Drive Peripheral Interface) port, providing local parameter access, fault diagnostics, speed reference adjustment, and start/stop control. Its plug-and-play compatibility means that replacing a failed or damaged HIM unit requires no modification to the drive’s internal parameter set, no rewiring of the control cabinet, and no changes to the PLC program running on the upstream controller — whether that is a ControlLogix, CompactLogix, MicroLogix, or SLC 500 platform. The module retains all drive parameters stored in the drive’s non-volatile memory, so the replacement HIM immediately reflects the existing configuration upon connection.

For sites migrating from older 1336 IMPACT or 1336 FORCE drive platforms to the 1336 PLUS architecture, the 1336-L5 HIM serves as the standardized local interface across the upgraded drive lineup. Engineers consolidating spare parts inventories will find that a single HIM model covers a broad range of 1336 PLUS drive ratings, from fractional horsepower to several hundred horsepower frames, reducing the number of unique spare part numbers required on the shelf.

Compatibility Comparison Table

Seamless Upgrade Solutions

A successful 1336 PLUS drive modernization project rarely involves a single component. During HIM replacement or full drive retrofit, maintenance teams typically address several adjacent components to ensure system reliability and reduce future unplanned downtime.

On the drive side, the 1336 PLUS power structure — including the 1336-BRF brake resistor assembly and the 1336-MOD-L2 communications adapter — should be inspected and replaced if showing signs of wear. The 1336-GM6 remote HIM mounting kit allows the 1336-L5 to be relocated to a control panel door, improving operator access without modifying the drive’s internal wiring. For sites using DeviceNet or ControlNet for supervisory control, the 1336-GM1 or 1336-GM2 communication option cards provide the network interface between the drive and the plant-level PLC network, and these cards remain compatible with the 1336-L5 HIM operating simultaneously on the DPI port.

Upstream, ControlLogix 1756-L series controllers and CompactLogix 1769-L series controllers communicating to the 1336 PLUS via a 1336-GM2 ControlNet adapter require no program changes when the HIM is swapped. The drive’s node address and I/O configuration remain intact. For older SLC 500 or PLC-5 installations still driving 1336 PLUS units via hardwired analog reference signals, the HIM replacement is entirely transparent — the analog input wiring at TB1 of the drive is unaffected.

Power distribution components such as the 1492-SP series supplementary protectors and 1492-FB series terminal blocks in the control cabinet do not require modification. Signal isolation between the drive’s analog outputs and the DCS historian or SCADA system — often handled by a Phoenix Contact or Weidmuller signal isolator — remains unchanged. If the site is also upgrading the operator station, a PanelView 800 or PanelView Plus 7 HMI communicating via EtherNet/IP to a ControlLogix controller can coexist with the local 1336-L5 HIM on the drive, providing both local and remote operator interfaces simultaneously.

For facilities performing a phased migration from 1336 PLUS to PowerFlex 400 or PowerFlex 525 drives, the 1336-L5 HIM supports continued operation of the legacy drives during the transition period, allowing engineering teams to validate the new drive configuration on non-critical loops before committing to a full cutover.

Retrofit Guidance FAQ

Q: Do I need to re-enter drive parameters after replacing the HIM?
No. The 1336 PLUS drive stores all parameters in its own non-volatile memory. The HIM is a read/write interface only — it does not store parameters internally. Connecting the replacement 1336-L5 HIM will immediately display the existing drive configuration.

Q: Is any wiring change required in the control cabinet?
No. The 1336-L5 connects via the DPI port on the front of the drive. If you are using a remote mounting kit (1336-GM6), the cable routing may need adjustment, but no control wiring at TB1 or TB2 is affected.

Q: Will the HIM replacement affect my PLC program or network node?
No. The upstream PLC — whether ControlLogix, CompactLogix, SLC 500, or MicroLogix — communicates with the drive via the communications option card (DeviceNet, ControlNet, or EtherNet/IP adapter), not through the HIM. The HIM operates independently on the DPI port.

Q: Is the 1336-L5 compatible with both 1336 PLUS and 1336 PLUS II drives?
Yes. The DPI interface is consistent across both drive generations. The HIM will function correctly on either platform.

Q: What is the physical installation space requirement?
The 1336-L5 HIM mounts directly to the drive’s front bezel using the integrated DPI connector and two retention clips. No additional panel cutout or DIN rail space is required for drive-mounted installation.

Q: Can I use this HIM while also running a DeviceNet or ControlNet communications card?
Yes. The DPI port supports simultaneous connection of the HIM and a communications option card. Both operate independently without conflict.
