Bremer Transformatoren UGE100 Replacement for UGE Series

Product Overview

Bremer Transformatoren UGE100 Replacement for UGE Series: Smooth Transition & Legacy System Compatibility

When your existing Bremer Transformatoren UGE Series voltage detection module reaches end-of-life or becomes unavailable through standard distribution channels, the UGE100 serves as the authoritative drop-in replacement and upgrade solution. Engineered to maintain backward compatibility with legacy UGE Series panel installations, the UGE100 preserves your existing wiring topology, DIN-rail mounting footprint, and terminal block assignments — eliminating the need for costly cabinet redesigns or rewiring campaigns. For industrial facilities operating continuous processes, this translates directly into minimized planned downtime and zero unplanned outages during the transition.

The UGE100 is a precision voltage detection relay designed for industrial control panels, switchgear assemblies, and power distribution systems where reliable undervoltage, overvoltage, or phase-loss detection is critical. Its compact form factor is dimensionally compatible with the original UGE Series housing, allowing direct substitution within existing control cabinet cutouts and DIN-rail segments without mechanical modification. Facilities that previously relied on the UGE Series alongside companion components such as Bremer Transformatoren current transformers, auxiliary power supply modules, and panel-mount signal conditioners will find the UGE100 integrates seamlessly into the same system architecture.

Seamless Upgrade Solutions

A successful UGE100 migration rarely involves the voltage detection module in isolation. In practice, control engineers undertaking a UGE Series retrofit will simultaneously evaluate adjacent components within the same panel or switchgear assembly. The UGE100 is commonly deployed alongside Bremer Transformatoren current transformers used for current measurement on the same bus bar, ensuring that both voltage and current monitoring functions are refreshed in a single maintenance window. Where the original installation included auxiliary relay modules for signal amplification or interposing, these can be retained or replaced with equivalent DIN-rail relay modules without affecting the UGE100’s output wiring.

In systems where the UGE Series fed signals into a legacy PLC input card — such as a Siemens S5 or early S7-300 digital input module — the UGE100’s relay output remains fully compatible with standard 24 VDC or 120 VAC digital input channels, requiring no changes to the PLC program logic or I/O address mapping. Similarly, facilities migrating from older OMRON C-series or Mitsubishi MELSEC A-series controllers to modern platforms will find that the UGE100’s hardwired relay interface bridges old and new control architectures without introducing communication protocol dependencies.

For panels that include DIN-rail power supply modules providing 24 VDC auxiliary power to the UGE Series, the UGE100 operates within the same supply voltage envelope, so existing PULS, Phoenix Contact, or WAGO power supply units require no adjustment. Where signal isolation is required between the UGE100 output and a sensitive analog input on a DCS or safety PLC, a standard DIN-rail signal isolator or galvanic separator can be inserted without modifying the UGE100’s wiring. Facilities that use Weidmüller or Phoenix Contact terminal blocks throughout their control cabinet will find the UGE100’s terminal pitch and wire gauge compatibility consistent with existing panel wiring standards.

Retrofit Guidance FAQ

Q: Can I reuse the existing wiring when replacing the old UGE Series module with the UGE100?
A: Yes. The UGE100 is designed as a direct drop-in replacement with a pin-compatible terminal block layout. In most installations, existing wire ferrules and labels can be transferred directly to the UGE100 terminals without re-termination, provided the wire gauge is within the UGE100’s specified range. Always verify terminal torque specifications against the UGE100 datasheet before final commissioning.

Q: Does replacing the UGE Series with the UGE100 require changes to the PLC program?
A: No program changes are required in the vast majority of retrofit scenarios. The UGE100 presents the same relay output (NO/NC contact) as the original UGE Series module. As long as the PLC input card reads a dry contact signal, the I/O address, rung logic, and alarm setpoints in the existing program remain valid. If the original module had adjustable trip thresholds, verify that the UGE100’s factory settings match the original calibration before energizing the system.

Q: Is the UGE100 compatible with the same communication protocol as the original UGE Series?
A: The UGE100 uses hardwired relay signaling — there is no fieldbus or serial communication protocol involved. This means it is inherently compatible with any control system that reads a digital contact input, regardless of whether the host PLC or DCS uses PROFIBUS, PROFINET, Modbus, DeviceNet, or EtherNet/IP for its primary network. The voltage detection function operates independently of the communication layer.

Q: Will the UGE100 fit in the same physical space as the original UGE Series module?
A: The UGE100 shares the same DIN-rail mounting standard and overall housing dimensions as the UGE Series, making it a direct physical replacement. No cabinet cutout modifications, DIN-rail extensions, or bracket adapters are required. If your panel uses a dedicated module carrier or snap-in retainer clip, confirm clip compatibility before installation.

Q: How should I handle the commissioning and functional test after installation?
A: After installing the UGE100 and reconnecting all terminals, perform a point-to-point wiring continuity check before energizing. Apply rated supply voltage and simulate an undervoltage or overvoltage condition using a variable autotransformer or test set to verify relay operation. Confirm that the PLC or DCS correctly registers the contact state change at the expected threshold. Document the as-found and as-left settings for your maintenance records.

Warranty Assurance

Every UGE100 shipped by TOPNLMS is covered by a 12-month warranty from the date of delivery. Prior to dispatch, each unit undergoes a functional outgoing inspection to verify relay operation, terminal integrity, and dimensional conformance. If a unit is found to be defective within the warranty period under normal operating conditions, TOPNLMS will arrange a replacement or repair at no additional cost to the buyer. Our after-sales response target is within 24 business hours of a warranty claim submission.

For procurement teams managing critical spare parts inventories, TOPNLMS maintains stock of the UGE100 and related Bremer Transformatoren components to support both planned maintenance schedules and emergency breakdown orders. Express shipping options are available to destinations worldwide, with standard dispatch from our Xiamen warehouse within 1–3 business days of order confirmation. All units are shipped with original manufacturer packaging where available, and include a test report or certificate of conformance upon request.
