CAN interfaceISO/IS 11898-2 with Philips 82C251 transceiver
Revision 1C isolation1 kV voltage insulation
Maximum baud rate500 kbit/s
Permissible bus loadDo not exceed 80%
Repeater propagation delayApproximately 150 ns from CAN1 to CAN2
Fault responseAffected segment disconnects automatically and reconnects after recovery
USE 01

Decouple two bus sections

DC/DC conversion and optocouplers separate the supply and signal paths of CAN1 and CAN2.

USE 02

Regenerate CAN traffic

The repeater transfers frames between both segments with the propagation delay specified by Lenze.

USE 03

Contain a segment fault

A persistent disturbance on one side triggers automatic separation while the opposite segment continues operating.

USE 04

Reconnect after recovery

The disconnected CAN side returns automatically when the permanent disturbance is no longer present.

USE 05

Provide service access

The repeater can be arranged as a service interface for online diagnostic access during machine operation.

USE 06

Show traffic and faults

Separate green transmit and red fault indicators expose the state of each network segment.

03
CAN REPEATER DECISIONS

Lenze EMF2176IB installation and sourcing FAQ

Clear purchasing guidance for dependable CAN network maintenance projects.

01

What isolation capability is documented for Lenze EMF2176IB hardware revision 1C?

Lenze's official knowledge base states that EMF2176IB from hardware revision 1C provides 1 kV voltage insulation; higher isolation requires a different repeater solution.

02

Which CAN networks can Lenze EMF2176IB join?

The official mounting instructions specify two ISO/IS 11898-2 CAN segments, integrated termination and the same baud rate on both sides, up to 500 kbit/s.

03

How can Lenze EMF2176IB support commissioning work?

It can be wired as a service interface so a diagnostic PC can access the system bus while the installation is operating.

04

How should Lenze EMF2176IB supply be confirmed for an older machine?

Provide the device and hardware-revision label because availability, condition and isolation capability must be checked against the exact installed version.

05

Which bus conditions must be copied when replacing Lenze EMF2176IB?

Keep both segment baud rates identical, verify polarity and termination, remain below the permitted bus load, and account for repeater delay and reduced total bus length.

06

What should a Lenze EMF2176IB manual and quotation request contain?

Request Lenze mounting instructions EDKMF2176X and send the label, hardware revision, supply voltage, network layout, baud rate, node count, quantity and destination.

PEOPLE BEHIND THE WORK

Professional Team

Experience, careful verification and patient communication support demanding automation purchases.

Professional automation sales and support team at work2017
Team development, product review and customer support during our 2017 growth stage.
EXPERIENCE

Nearly 10 Years of Industry Experience

Our team members have an average of more than 10 years of industry experience. We have worked with customers worldwide, including those from India, Germany, Sweden, Italy, the United Kingdom, France, and Canada, as well as many other countries. Throughout our careers, we have collectively completed over 3,000 orders and established long-term business relationships with customers across nearly 30 countries.

JUDGMENT

Professional Product Judgment

We can often identify a product’s manufacturer, series, configuration, and function from its model number or nameplate photo. We also understand how revisions, firmware, and specifications affect compatibility and whether an alternative model can be used safely.

SERVICE

Sincere and Patient Service

Our team treats every inquiry sincerely and answers every question patiently. Even for complex requests, we verify and respond to each detail instead of providing a rushed or uncertain answer.

In Practice — Indian discontinued control module

An Indian customer urgently needed a discontinued control module after several suppliers reported no stock. We identified its exact revision and function from the nameplate, checked compatible alternatives, and contacted factory and warehouse channels to locate matching inventory. After installation, the customer confirmed that the module operated correctly and later asked us to source additional spare parts.

In Practice — German mixed-product inquiry

A German customer sent a mixed list of automation products and asked repeated questions about revisions, condition, photos, and delivery. Our team organized the requirements, checked every item, and replied point by point. The customer said our detailed communication made the purchasing decision easier and continued sending us new inquiries.
