Why Signal Link

A full signal conditioner in a single DIN slot.

Built for OEMs and system integrators who need precision strain-gauge measurement inside the cabinet. Commissioning, calibration and live troubleshooting all happen at the rail, no laptop required.

The module

Drops in on the rail.

1,000,000-count measurement, an OLED, RS-485 Modbus and three relays, all in cabinet-grade hardware.

Connectivity

Talk to anything in the cabinet.

4–20 mA, 0–10 V and bipolar analog, RS-485 Modbus-RTU to 32 nodes, and three Form-A relays: legacy and modern controls from one source.

The display

Commission at the rail.
No laptop required.

The OLED shows live weight, state and diagnostics right on the module, so calibration, tare and setpoints happen where the wires are, not back at a desk.

The home screen: gross, net and motion state at a glance, readable across the cabinet.
Throughput, filtering and zero behaviour: how the reading settles before anything acts on it.
Decimals, count-by and units, plus calibration by test weight or keyed-in mV/V.
Pick the analog signal, scale it to your range and trim it against what the PLC reads.
RS-485 Modbus and USB-C: baud rate, framing, station address and response delay.
Setpoints for the three relays: checkweighing, pass band, or two-speed filling.
Diagnostics and housekeeping: live mV/V, display test, password and factory reset.

Which signal conditioner do you need? Three models, side by side.

All three turn load cell mV/V into a signal a controller can read. The Signal Link adds a display, digital communication and relay control; the LCT6 models are simpler, lower-cost amplifiers for plain analog conversion.

A conditioner is one link in the chain. One catalog, one order.

Every conditioner on this page reads load cells, and most installs add a junction box and shielded cable. All of it comes off the same shelf, on the same order.

Transcell load cells

Load Cells

Every mV/V source the conditioners read: S-beam, single-point, canister, inline and more.

Questions

Signal Link, answered.

How many load cells can one Signal Link drive?

Up to eight 350 Ω load cells in parallel (direct or through a junction box) on its 5 V excitation supply, with a ±4.5 mV/V input range.

Will it connect to my PLC?

Yes. Choose 0–10 V, ±10 V, 4–20 mA or ±20 mA analog output scaled to your own endpoints, or poll it over RS-485 Modbus-RTU. Built-in PLC calibration points at 0 / 25 / 50 / 75 / 100% make loop checkout quick.

Can I network more than one module?

Up to 32 units daisy-chain on a single half-duplex RS-485 Modbus-RTU bus. The two AA/BB terminal pairs are paralleled so chain wiring needs no splices. Just fit a 120 Ω terminator at each end node.

Does it take 4-wire or 6-wire load cells?

Both. Six-wire load cells use the remote-sense terminals for full accuracy over long runs; for four-wire load cells, short SEN to EXC. A dedicated TEDS terminal supports plug-and-play transducer identification.

Do I need software to set it up?

No. Calibration, filtering, scaling and relay logic are all on-device through the OLED and four-key pad. The USB-C port is optional: it appears as a virtual COM port for PC setup and firmware updates.

What can the relays do?

Three Form-A relays (5 A · 250 VAC / 30 VDC) run on-board fill, pass-band and check-weigh logic against your setpoints, and an opto-isolated trigger input (10–30 VDC) starts the cycle: simple dosing and grading without a PLC in the loop.
