New DAQ Amplifier Modules for IOLITE® Data Acquisition Systems

Dewesoft has released 4 new I/O amplifier modules for the IOLITE Rack, IOLITE LX, and IOLITE modular data acquisition and real-time control systems:

• IOLITE-8xSTGS - 8-channel strain gauge amplifier module

• IOLITE-16xLV - 16-channel voltage amplifier module

• IOLITEi-8xLA - 8-channel current amplifier module

• IOLITE-16xAO - 16-channel analog output amplifier module

As with all standard IOLITE amplifier modules, these new modules are equipped with two parallel EtherCAT data buses for both high-quality buffered data acquisition and real-time control. The modules are compatible and can be used in any IOLITE main-frame chassis:

• IOLITE R8,

• IOLITE R12, or

• IOLITE LX.

IOLITE-8xSTGS - 8-channel strain gauge amplifier module

IOLITE-8xSTGS is an 8-channel strain gauge module. It supports the following inputs:

• full-bridge sensors,

• half-bridge sensors,

• quarter-bridge sensors,

• voltage,

• potentiometer mode.

Predefined bridge ranges are 2 mV/V, 20 mV/V, 200 mV/V (free programmable between 2 mV/V and 1000 mV/V), where users can select the excitation voltage of 1 V, 2 V, or 5 V.

IOLITE-8xSTGS includes a new 24-bit oversampled sigma-delta analog-to-digital converter with a sampling rate of up to 20 kS/s which features an option for low latency Sinc5 filter, a perfect solution for control applications.

IOLITE-8xSTGS features an internal 100 kΩ shunt which can be used in the positive or negative leg. Configuration is software selectable. DewesoftX software enables shunting, shorting, sensor balancing, and lead wire compensation. Additionally, the TEDS sensor interface is supported as well.

The advantage of IOLITE-8xSTGS is in long-term stability and low power consumption.

IOLITE-8xSTGS is available with two different input connector types:

• Terminal block and

• D-SUB37.

IOLITE-16xAO - 16-channel analog output amplifier module

The IOLITE-16xAO is a 16-channel analog output module designed for industrial applications.

This module offers 16 analog voltage output channels in the range of ±10 V.

Outputs are galvanically isolated from the main power supply ground.

Additionally, non-isolated supply voltage with a current limit of 2 A can be used from PWR OUT pins.

The input connector of IOLITE-16xAO is a terminal block OMNIMATE Signal SL Series. The IOLITE-16xAO module has 9-pin terminal block connectors with a 2.50 mm pitch for analog output. 8 pins on a 9-pin connector bank are used for digital inputs and pin 9 for common GND.

Additionally, there is a 2-pin terminal block connector with a 2.50 mm pitch for the PWR OUT function. 

IOLITE-16xAO is a perfect tool for signal conditioning.
