ABB 1SFA899019R7002 PSHMI-2 HMI Module for PSTB370–PSTB1050 Softstarters

ABB 1SFA899019R7002 PSHMI-2 HMI Module for PSTB370–PSTB1050 Softstarters

ABB 1SFA899019R7002 is the PSHMI-2 HMI module designed for the ABB PSTB
softstarter family. The unit provides the operator interface associated
with PSTB370 through PSTB1050 softstarters and forms an important part
of the front control and monitoring arrangement of these high-power
softstarter systems. In ABB documentation, the product is identified as
an HMI module with the designation PSHMI-2 and order code
1SFA899019R7002.

The PSHMI-2 configuration is intended for the larger PSTB softstarter
range, covering PSTB370 to PSTB1050. Unlike a basic display component,
the complete HMI module is an integrated assembly associated with the
softstarter’s operator interface. ABB documentation identifies the
assembly as including the HMI together with the display, keyboard,
label, and related low-voltage and high-voltage board assemblies.

ABB 1SFA899019R7002 Product Overview

The human-machine interface is a central part of an industrial
softstarter because it provides the connection between the control
electronics and the equipment operator. The ABB 1SFA899019R7002
PSHMI-2 module is designed specifically for the PSTB platform and
provides the physical interface required for operating and observing
the softstarter.

The PSTB series is intended for applications involving larger motor
loads, and the PSHMI-2 configuration is associated with PSTB370,
PSTB470, PSTB570, PSTB720, PSTB840, and PSTB1050 class softstarters
within the applicable PSTB range. The HMI assembly therefore serves
as an important interface component in systems where operators need
access to softstarter information and controls.

The order code 1SFA899019R7002 is important when identifying the correct
HMI assembly because ABB offers several related HMI configurations.
For example, PSHMI-1 is associated with smaller PST softstarter
models, while PSHMI-2 is intended for the larger PSTB range. Correct
identification of the order code helps ensure compatibility with the
intended softstarter family.

Technical Specifications

PSHMI-2 Interface for PSTB Softstarters

The ABB PSHMI-2 provides the operator-facing interface of the
applicable PSTB softstarter. Through the HMI arrangement, personnel
can interact with the softstarter’s control system and obtain access
to information presented by the device. This interface is especially
relevant in motor control installations where the softstarter is
installed inside an industrial electrical cabinet.

The HMI assembly combines several elements into one coordinated
component. The display provides the visual interface, while the
keyboard provides the physical control interface. The associated
label supports identification and operation of the front panel.
According to ABB’s spare-parts documentation, the PSHMI-2 assembly
also incorporates the relevant LV and HV board components.

Compatibility with PSTB370–PSTB1050

Compatibility is one of the most important considerations when
selecting the ABB 1SFA899019R7002. ABB identifies PSHMI-2 specifically
for the PSTB370 through PSTB1050 softstarter range. This means that
the order code should be checked against the softstarter type before
selecting the HMI assembly for a control system.

The PSTB family includes several current and power classes. Although
these softstarters share the same general platform concept, their
associated components can have different specifications. The
1SFA899019R7002 designation therefore provides an important reference
when identifying the appropriate HMI module for a PSTB installation.

HMI Module Construction

ABB describes the PSHMI-2 as an HMI module that includes the front
interface components and associated control electronics. The assembly
incorporates the display and keyboard together with the label and
LV/HV board elements. This integrated construction makes the module
more than a standalone display and allows it to function as a complete
operator-interface assembly for the applicable PSTB softstarter.

The physical dimensions listed for the product are approximately
250 mm in width, 400 mm in height, and 30 mm in depth, with a net
product weight of approximately 0.4 kg. These dimensions are useful
when evaluating cabinet arrangements, replacement requirements, and
mechanical compatibility within the PSTB softstarter enclosure.

Role in Industrial Motor Control

Softstarters are commonly used to manage the starting behavior of
electric motors and to reduce the electrical and mechanical stresses
associated with direct starting. In such installations, the HMI
provides an accessible operator interface for the softstarter control
system. The PSHMI-2 therefore contributes to the overall usability
of the PSTB installation by providing the physical interface between
the operator and the softstarter electronics.

In industrial environments, the HMI may be located on the front of
the softstarter cabinet where operating personnel can interact with
the equipment. The display and keyboard arrangement allows the
interface to be used as part of the softstarter’s control and
monitoring architecture. Its integration with the associated boards
makes the PSHMI-2 a dedicated component of the PSTB platform rather
than a generic HMI device.

Identification and Replacement Considerations

When identifying an ABB PSHMI-2 module, the complete order code
1SFA899019R7002 should be used together with the softstarter type.
This is particularly important because ABB uses similar product
designations for different PST and PSTB HMI configurations.

The PSTB model installed in the system should be compared with the
applicable range before selecting the HMI module. For the
1SFA899019R7002, ABB identifies the compatible range as PSTB370
through PSTB1050. Checking both the order code and the softstarter
model provides a more reliable method of component identification
than relying only on the general term “PSTB HMI.”

ABB PSHMI-2 Documentation

ABB documentation associated with 1SFA899019R7002 includes product
information, technical documentation, operating instructions, and
dimensional information. The documented product designation is
PSHMI-2, while the order code provides the precise ABB identification
for this HMI module.

For engineering, maintenance, and system identification purposes,
retaining the complete order code is recommended. The designation
1SFA899019R7002 identifies the specific PSHMI-2 configuration and
distinguishes it from other ABB HMI assemblies used with different
softstarter families.

Conclusion

ABB 1SFA899019R7002 is the PSHMI-2 HMI module for ABB PSTB370 to
PSTB1050 softstarters. It is an integrated operator-interface assembly
incorporating the HMI, display, keyboard, label, and associated
low-voltage and high-voltage board components. Its dedicated design
makes it an important interface component for the applicable PSTB
softstarter platform.

With its specific PSHMI-2 designation and clearly defined
1SFA899019R7002 order code, the module can be accurately identified
for engineering and maintenance applications involving ABB PSTB
softstarter systems. Understanding the relationship between the HMI
module and the compatible PSTB370–PSTB1050 range is essential when
selecting this component for an industrial motor control installation.
