Define Instruments G3 IoT Manual

Data visibility for better machine performance
The G3 IoT collates signals from industrial equipment
for processing and publishing to the Cloud. Designed
for monitoring small machines and automation systems,
it enables data visibility for determining machine health
or process efficiency. Industrial grade digital inputs,
relay contacts and analog process input channels
easily link process sensor inputs and standalone legacy
automation such as PLCs, variable frequency drives and
other discrete control systems to IoT cloud services.
Direct wireless interface to field operating data
The G3 IoT converts, conditions and processes analog sig-
nals directly to wireless Wi-Fi (802.11bgn), and the built-in
cloud interface sends data from your machine directly to the
Cloud. A 4G modem (Cat-M1/Cat-1) or Ethernet interface can also be added.
Easily integrates with your existing automation equipment
The G3 IoT natively supports the MQTT communications protocol for Industrial
IoT applications, and Modbus master/slave protocols for directly interfacing
with metering and control automation equipment. The unit's onboard logic
engine allows customization tailored to specific measurement and monitoring
requirements.
Extra cloud interface security and Store and Forward data integrity
The G3 IoT provides peace of mind with Transport Layer Security (TLS 1.2) protocol. In the
event of a network communications failure the G3 IoT Store and Forward function buffers
data locally, forwarding to the cloud server once network communications are reinstated,
securely monitoring and recording with total data integrity.
