PRODUCT DESCRIPTION
1KHL015545R0002 O4LE Audio-frequency interface module
ABB 1KHL015545R0002 O4LE is an audio-frequency interface module associated with the ETL600 power-line-carrier platform. The O4LE interface supports analog telephony, teleoperation and external teleprotection services through programmable signal paths.
Its documented interface architecture includes four four-wire 600 ohm AF ports, two-wire FXS and FXO telephone ports, E&M signaling and an external teleprotection boost input. One board supports a telephony channel and up to two AF channels for teleoperation or external protection, with digital filters and routing configured through HMI600.

SYSTEM INTEGRATION
Integrate 1KHL015545R0002 O4LE audio-frequency interface module
Map AF1–AF4 and the telephone interfaces to the intended ETL600 service plan. AF1 can carry four-wire telephony, while the subscriber-side two-wire port is shared with the front service-phone socket. A relay selects the active subscriber/service connection.
The O4LE DSP supports up to four configurable filters. When telephony is enabled, two filters are used for speech and only two transit filters remain available. The internal TDM bus links the board with P4LT; HMI600 defines the service routing rather than a generic PLC I/O map.
Its documented interface architecture includes four four-wire 600 ohm AF ports, two-wire FXS and FXO telephone ports, E&M signaling and an external teleprotection boost input. One board supports a telephony channel and up to two AF channels for teleoperation or external protection, with digital filters and routing configured through HMI600.
Features:
- Four 600 ohm four-wire AF ports
- HMI600 filter and service routing
- Shared FXS/service-phone connection
The 1KHL015545R0002 O4LE audio-frequency interface module requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify 1KHL015545R0002 O4LE audio-frequency interface module
Retain the complete O4LE part number and the ETL600 release information before changing the module. Preserve the HMI600 configuration and record AF-port levels, impedance selection, telephone signaling and external boost wiring.
Test the configured voice, teleoperation or external protection paths after replacement, including service-phone selection and channel-availability signaling. The four AF ports, FXS and FXO connections have different roles and must not be treated as interchangeable terminal groups.
It uses the documented internal TDM-bus connection.
Features:
- Retain the ETL600 release and service configuration
- Check AF levels and signaling connections
- Exercise selected voice and protection paths
The 1KHL015545R0002 O4LE audio-frequency interface module requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 1KHL015545R0002 O4LE
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Is O4LE a general-purpose PowerPC PLC controller?
No. The ETL600 manufacturer documentation describes O4LE as an audio-frequency interface board for analog services. -
How many four-wire AF interfaces does an O4LE board provide?
It provides four 600 ohm ports identified as AF1 through AF4. -
Can all four digital filters remain available for transit when telephony is enabled?
No. Telephony uses two filters, leaving two transit filters on that board. -
What is shared between the subscriber port and service-phone socket?
The two-wire FXS interface is shared; a switchover relay permits only one of the two connections to be active at a time. -
Which ETL600 software configures the O4LE service routing?
The documented interface program is HMI600. -
How does O4LE communicate internally with P4LT?
It uses the documented internal TDM-bus connection. -
What records help match 1KHL015545R0002 for an installed ETL600?
Provide the full board label, terminal release and the current HMI600 service configuration, including AF and telephone assignments. -
Can the configured telephone and AF service details accompany a spares request?
Yes. Include the HMI600 service record and identify any required cables or accessories so the quoted scope matches the installed interface.
