TXDIN1600S-Transmitter

Supported Applications

The Omega TXDIN1600S is a smart powered bridge amplifier designed for strain gauge and load cell signal conditioning. It functions as a DIN rail mount transmitter that scales input signals to process values, supporting applications requiring voltage or current re-transmission of sensor data.

Operating Conditions & Performance

The TXDIN1600S operates with an ambient temperature range of -30 to 70°C (-22 to 158°F) and a storage ambient range of -30 to 70°C (-22 to 158°F). Configuration is specified for an ambient environment of 10 to 30°C (50 to 86°F). The device maintains operation within a humidity rating of 10 to 90% RH (non condensing) and features an enclosure protection level of IP65.

Performance specifications include bridge input linearity of ± 0.01% and drift less than ± 0.05%. The device utilizes ratio metric measurement for high stability with a sample rate selectable at 10 or 80 SPS (samples per second). Output accuracy is defined as (mA out/2000) or 5 µA whichever is the greater, with a drift of 1 µA/°C. Voltage output accuracy is ± 5 mV.

Measurement and Signal Parameters

• Bridge Input: -7.6 to 7.6 mV/V (-38 to 38) mV at 5V excitation; Four wire radimetric type.
• Bridge Excitation: 5 Volts DC ± 0.1 V @ 59 mA, supporting total bridge impedance from 85 to 10000 Ω (operates with four 350 Ω cell in parallel).
• Response Time: Filter selectable from 1 to 20 seconds to reach 70% of final value.

Configuration Options

The TXDIN1600S series supports configurable output signals, calibration scaling, and user interface options. The device is housed in a DIN rail enclosure (style DIN 43880) constructed from Polyimide 6.6 with dimensions of 56.4 mm width x 90 mm height x 17.5 mm depth.

Output Signal Options

• Current Source: Range (0 to 21.5) mA, max load 750 Ω.
• Current Sink: Range 0 to 21.5 mA, supply 10 to 30 Vdc, voltage effect 0.2 µA/V.
• Voltage Output: 0 to 10.1 V or -10.1 to 10.1 V with ± 2 mA current drive and min load 5000 Ω @ 10 V.

User Interface & Configuration

• Calibration: Supports (2 to 6) points signal against process scaling, including active calibration against live load cell and remote set tare offset with programmable user set point.
• Front Panel: Independent “Low” and “High” push buttons allow manual setting of low and high output points. LED indication shows green when output is -0.1 to 100.1%, red otherwise.
• Digital Interface: USB 2.0 at 19,200 baud for PC running Windows XP or later; supports process units (4 characters) and tag number (20 characters).

Power & Electrical Connections

• Supply: 10 to 48 Vdc, 10 to 32 Vac protected by internal 500 mA resettable fuse; power consumption < 1 W full power.
• Isolation: Supply to input to output 500 Vdc.
• Tare Input: Remote volt free contact, up to 10 meter distance.
• Terminals: Screw terminals accepting wire size maximum 2.5 mm (0.10").

Key Product Differences

The TXDIN1600S is a single model family designated as the DIN-rail mount load-cell transmitter. If configuration is not specified at the time of order, the product ships with default settings: 2 mV/V input and 4 to 20 mA output range.
