Key parameters
Washdown-ready 304 stainless LED indicator for general-purpose weighing and basic batch/fill — IP69K enclosure, full numeric keypad, multi-port communications, and a configurable batch engine with onboard digital I/O.
Key advantages
- IP69K 304 stainless — Built for high-pressure, high-temperature washdown; RJ45 Ethernet option drops rating to IP66 when the cover is in place.
- Bright LED HMI — Seven 0.8 in seven-segment digits, full numeric keypad, battery-backed time/date, formattable tickets.
- Batch / setpoint engine — Up to 20 setpoints (22 configurable types on OEM page) with four onboard TTL digital I/O and built-in batch presets.
- Multi-port I/O — Two RS-232, full-duplex RS-485, USB device, and 10/100 Ethernet TCP/IP standard on the series literature.
- Scale-ready excitation — 10 VDC excitation for 8 × 350 Ω or 16 × 700 Ω load cells; optional 16-bit analog output card.
Typical applications
- General-purpose industrial bench and floor-scale indication.
- Basic automated fill/batch sequences with digital I/O.
- Food and washdown areas needing IP69K stainless fronts.
- Local/remote indicator pairs and ticketed shipping/receiving.
Selection guide
- Power cord region — US / EU / UK / AUS cord variants on 115–230 VAC universal supply.
- Analog output — Optional 16-bit card (0–10 V, 0–20 mA, 4–20 mA class outputs per literature).
- Ethernet hardware — RJ45 option available; confirm IP66 cover practice for washdown.
- Trade approvals — OEM publishes NTEP / Measurement Canada / OIML / UL/cUL / CE literature — confirm current certificate for your ship-to before Legal for Trade use.
Common mistakes
- Assuming IP69K still applies with the RJ45 cover open or missing — OEM states IP66 with RJ45 and only when the cover is in place.
- Ordering without the analog-output card when the PLC needs 4–20 mA / 0–10 V from the indicator.
- Skipping Legal for Trade certificate confirmation for the destination country.
- Undersizing excitation budget for the planned load-cell count/impedance.
When to RFQ / what to tell us
- Cord region; analog-output and RJ45 options.
- Scale capacity/cell count; batch or Local/Remote need.
- Trade-approval region; quantity; ship-to.

FAQ
Q: Is the 680 washdown-rated? A: OEM rates the stainless enclosure IP69K; with the RJ45 Ethernet option the rating is IP66 when the cover is in place.
Q: Can it run basic batching? A: Yes — configurable setpoints, four digital I/O, and built-in batch presets support multi-step fill sequences.
Q: What should I send for a quote? A: Cord region, analog/RJ45 options, scale details, approval region, quantity, ship-to.
