Non-OMRON Alternatives for K3HB-VLC — Full List

Recap of K3HB-VLC mandatory requirements for candidate replacements:

✅ 96×48 mm / 1/8 DIN cut-out, strain-gauge Load-cell mV low-level direct input, sensor excitation DC5 V / 10 V @ 100 mA

✅ Hardware terminal-based external event inputs: ZERO / HOLD / 다시 놓기 (for automatic line triggering; distinguishes from simple key-operated weighing meters)

✅ Multi-level OK/NG judgment outputs (5-level HH/H/PASS/L/LL preferred; minimum 3-level)

✅ 5-digit display, ~50 Hz high-speed sampling (for press-fit force / dynamic force measurement; not for low-speed commercial scales)

✅ Optional relay / 4-20 mA analog / RS485 Modbus

❌ Many standard 96×48 weighing meters only support keypad zeroing, lack external DI, run slow sampling and are unsuitable for K3HB-VLC-style automated force-measurement applications.

1. Other Japanese Brands (Best-fit for press-fit / force-measurement production lines)
2. Unipulse F331 (Top-rank alternative)

치수: 96×48 mm identical cut-out, strain-gauge / mV dedicated input.

Key matching features: External DI (ZERO, PEAK/HOLD, 다시 놓기), HH/HI/OK/LO/LL multi-level judgment, peak-/valley-hold, sampling up to 300 Hz, selectable excitation 5 V / 10 다섯.

출력: Relay judgment, 4-20 엄마 / 0-10 V analog, RS485 Modbus (option), USB standard.

차이점: Default power supply DC24 V; no AC100-240 V version. 5-level logic and terminal pin-out differ from K3HB-VLC; re-wiring required. No DeviceNet.

Ideal use-case: Automated press-fit, force-value OK-NG judgment with external trigger hold. OEM-class force-measurement panel meter.

2. SHIMADZU LCM-800

96×48, LC mV input, 50 Hz sampling, 5-digit red-green switchable display, 5-level comparison outputs, external zero / hold inputs.

10 V excitation. Accuracy and dynamic performance comparable to K3HB-VLC. Widely used industrial force meter.

차이점: 더 높은 가격, limited distribution channels; 교류 / 24 V power variants are separate models.

응용: High-speed force testing, test machines, matched with Shimadzu sensors.

3. Valcom VMM6

96×48, strain-mV dedicated input, external S/H hold, external digital ZERO, multi-level comparison outputs.

Frequently seen on Japanese equipment; high noise immunity for pressure / load judgment.

차이점: Moderate sampling rate; analog and communication are optional add-ons.

4. Autonics DI-100LC (메모: CT series are counters, not load-cell meters)

96×48, Load-cell input, 10 V excitation, external zero + 2-channel alarm, optional RS485 / 비슷한 물건.

차이점: 오직 2- / 3-level alarm, no native 5-level HH/H/PASS/L/LL, limited event inputs, 25 Hz sampling rate.

Suitable for simple upper-lower-limit force measurement or weight sorting. Not for original 5-level-judgment production lines.

5. NMB / AND small-form-factor force meters

Also offer 96×48 LC panel meters, mostly bundled with their own sensors. Low general-purpose flexibility and high cost; seldom chosen as universal replacements.

1. 유럽 ​​사람 & 미국 브랜드 (High-precision, premium force-/test-measurement scenarios)
2. HBM WTX110

메모: Standard variant is 96×96, not 96×48; compact variants exist. LC mV input, 높은 정확도, 고속, 풍부한 기능.

강점: Native compatibility with HBM sensors, complete calibration utilities, robust industrial noise performance.

제한사항: Mismatched cut-out, high price; oriented as amplifier / transmitter rather than judgment-capable panel meter. Only consider if panel cut-out modification is acceptable.

2. Flintec / ADI LC-50K

96×48, LC input, alarm outputs. Optimized for static weighing rather than dynamic force measurement; limited external event DI capability.

3. Vishay / Zemic indicator units

Most are 96×96 form factor; cut-out mismatch.

요약: 유럽 ​​사람 / American product lines have almost no native 96×48 panel meters combining full external event DI plus 5-level judgment. Replacement cost is high; prioritize Japanese or domestic options.

III. 국내 브랜드 (비용 효율적; many models purpose-built to replace K3HB force-measurement applications)

✅ Tier 1 (모든 기능을 갖춘, qualified for automated force-measurement replacement)

1. Jaiman GM-8804 / M02

96×48 cut-out, direct Load-cell mV input, 10 V excitation. 계전기 + 비슷한 물건 + RS485 built-in; no extra option boards required unlike K3HB.

Supports hardware-terminal external ZERO, HOLD, RESET DI inputs, peak-valley hold, multi-level judgment, sampling adjustable from 50 Hz up to 960 Hz.

Currently the most widely-adopted domestic drop-in for K3HB-VLC on production lines.

차이점: No red-green color-changing display; excitation mostly fixed at 10 V (verify for 5 V sensors); menu architecture changed; full recalibration mandatory.

M02: More compact, high-speed sampling; GM-8804: General-purpose workhorse.

2. Sibata SBT953

96×48, mV force input, external zero / hold, peak-valley functions, 계전기 + 4-20 엄마 + RS485, Chinese-language menu.

Popular domestic option for press-fit and force sorting.

3. Zhimei PT650

96×48, LC input, zero / 정점 / 경보 / transmission. Economical stable model.

제한사항: Weak external event-input capability; keypad-dominated zeroing. OK-NG basic use only; not recommended for complex timing-DI workflows.

✅ Tier 2 (Economy class, simple weighing / limit-alarm only; unsuitable for original automated event logic)

Changchen XMT800-LC, Ditaier CHB, Dayang DY800: Support mV input and alarm outputs. Typically only one external zero input; no independent HOLD / 다시 놓기; slow sampling; no 5-level judgment.

Use-case: K3HB-VLC used merely for weight indication plus dual-limit alarm. Do not apply if original installation uses external HOLD, TIMING or multi-bank / 5-level outputs.

1. Replacement Matching Summary Table

1. Critical Selection Pitfalls
2. Distinguish force-measurement mV panel meters from general weighing indicators

Most 96×48 domestic weighing meters target hopper / platform scales: heavy digital filtering, slow sampling, keypad-only tare, no external timing DI, no trigger-capable peak-hold. These cannot substitute K3HB-VLC for press-fit force / on-line judgment. Confirm hardware-terminal external zero and external-hold functions before ordering.

2. Verify excitation voltage: Legacy K3HB-VLC B-variant =10 V, E-variant =5 V @100 mA. Many alternatives use fixed 10 V excitation. For 5 V-rated load cells prioritize models with switchable excitation such as F331.
3. Cut-out dimension ≠ mounting depth: 96×48 front-panel footprint is compatible across models, but rear depth and terminal layouts differ completely. All replacements require re-wiring. Legacy K33 option boards are 100 % non-reusable.
4. If original system relies on HH/H/PASS/L/LL 5-level outputs: Avoid models limited to dual-limit alarm (Autonics DI-100LC, Zhimei PT650, 등.).
5. Legacy DeviceNet installations: None of the non-OMRON alternatives support DeviceNet. 해결책: retain second-hand K3HB-VLC or deploy RS485-to-DeviceNet protocol gateway.
6. Zero-point and full-scale physical recalibration is mandatory after replacement. Parameter migration from K3HB-VLC is not possible.
