The Omega DPS20-LV-AO is an economical 1/8 DIN panel meter for load-cell and weighing applications, supplied with analog on the 11 to 60 Vdc / 24-48 Vac power input. It accepts 4- and 6-wire cells with configurable 5 or 10 Vdc excitation, characterizes the cell by sensitivity, nominal load and excitation, and lets you rescale reading units independently — all on a bright 6-digit red LED behind a NEMA 4 (IP65) front.
Specifications per the OMEGA DPS20 Series product datasheet and User’s Guide (M5760).
Overview
The OMEGA DPS20 brings high-performance load-cell metering to a compact 1/8 DIN panel-mount package. It accepts 4- and 6-wire cells and provides 5 Vdc and 10 Vdc configurable excitation to power the load cell, with two power supply options for high and low AC/DC supplies so the unit suits global installations. Independent scaling of the load-cell signal and reading units, prevention of false tares, stability alarms and a configurable rear terminal round out a meter built for real-world weighing.
Best for
- Assembly-line, batching and process weighing on a panel front
- Control panels and laboratory benches needing a compact load-cell readout
- Applications using 1, 2 or 3 mV/V cells on 4- or 6-wire connections
- Retransmitting weight to a PLC or recorder via isolated analog output
Key Features
Load-cell ready
Accepts 1, 2 and 3 mV/V cells on 4- or 6-wire connections with configurable 5 or 10 Vdc excitation — drives up to 8 standard 350 ohm cells at 5 Vdc, 4 at 10 Vdc.
Independent scaling
Characterize the cell by sensitivity, nominal load and excitation, then rescale reading units independently without re-characterizing the load cell.
0.05% FS accuracy
0.05% of full scale at 25 C with 50 ppm/C thermal stability, 20 Mohm input impedance and a recursive display filter for steady readings.
Smart tare
Configurable tare from the front key, rear terminal or auto-tare, with a maximum-tare limit that prevents undesired tares plus stability alarms.
Scalable I/O
Supplied with 1 isolated analog output (4/20 mA or 0/10 Vdc). Relays configure as max/min alarms with setpoint, hysteresis, delays, dual setpoints and latching.
NEMA 4 panel front
1/8 DIN bezel with NEMA 4 (IP65) front protection, plug-in screw terminals (male and female included) and 5 brightness levels with password protection.

Frequently Asked Questions
What load cells does the Omega DPS20 work with?
The DPS20 accepts 1, 2 and 3 mV/V load cells (and others) on 4- or 6-wire connections with configurable 5 or 10 Vdc excitation. At 5 Vdc it drives up to eight standard 350 ohm cells; at 10 Vdc, up to four.
How accurate is the DPS20?
Accuracy is 0.05% of full scale at 25 C, with 50 ppm/C thermal stability and 20 Mohm input impedance. Acquisition rate is configurable at 16, 50 or 60 readings per second.
What power supply does the DPS20-LV-AO use?
This version uses the 11 to 60 Vdc and 24/48 Vac (low-voltage, isolated 1500 Veff) input. The low-voltage option suits 24/48 Vac and 11 to 60 Vdc panels.
What does the analog output provide?
The AO module gives an isolated 4/20 mA or 0/10 Vdc retransmission output (mA active or passive), 0.1% FS, 1000 Vdc isolation, on plug-in screw terminals.
Does it fit a standard 1/8 DIN cut-out?
Yes. The front bezel is 96 x 48 mm (1/8 DIN) with a 92 x 44 mm cut-out and 91 mm depth including terminals. Front protection is NEMA 4 (IP65); both male and female plug-in terminals are included.
