I/O Modules

3.6 ADAM-4016 Analog Input/Output Module

A strain gauge input module uses a microprocessor-controlled integrating A/D converter to convert sensor voltage or current signals into digital data for load cell and stress measurement. The digital data are then translated into either, two’s complement hexadecimal format or percentage of full-scale range (FSR) according to the module’s configuration. When prompted by the host computer, the data are sent through a standard RS-485 interface.

The strain gauge input module offers signal conditioning, A/D conversion, ranging, and RS-485 digital communication functions. They protect your equipment from power surges at the ground terminal by providing opto-isolation of the A/D input and up to 3000 VDC

transformer based isolation.

Excitation Voltage Output

A strain gauge input module can supply single channel voltage output for excitation. The module receives digital input from the host computer, and the format of the data is engineering units. It then uses its microprocessor-controlled D/A converter to convert the digital data into output signals.

Strain gauge input modules protect your equipment from power surges at the ground terminal by providing opto-isolation of the D/A output and up to 3000 VDC transformer-based isolation.

Digital Outputs

A strain gauge input module also contains four digital outputs. Outputs are open-collector transistor switches that may be controlled by the host computer. They can control solid-state relays which can be applied to heaters, pumps, and other electrical controlled equipments.

Alarm signaling

Strain Gauge input modules include High and Low alarm functions. High and Low alarm limits may be downloaded into the module’s EEPROM by the host computer.

The alarm functions can be enabled or disabled remotely. When the alarm function is enabled, both Digital Output channels are used to indicate the High and Low alarm states. Digital Output channel 1 (DO1) equals to High alarm state and Digital Output channel 0 (DO0) equals to Low alarm state. The High and Low alarm state can be read at any time by the host computer.
