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

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. Dewesoft X 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.
