Control, Logging and Telemetry Module
Valeport’s EnviroLog 4G is a rugged, ultra-low-power 4G remote control, telemetry and logging module providing a flexible solution for harsh environmental conditions. It has an industry-leading range of data collection, delivery and management options. The EnviroLog 4G is effectively a “platform” that offers fully scriptable operational scenarios for the collection, handling and delivery of data from a number of Valeport instruments.
For battery operation, the EnviroLog 4G stays in ultra-low-power sleep mode and wakes up on a trigger or internal timer to collect data from the interfaced instrument(s). It will transmit the data as scheduled, or on scripted conditions.
• 2 x serial: RS232, RS485, Modbus
• 2 x digital/pulse-count/event detection inputs
• 1 x 24-bit differential ADC (e.g. pressure transducer)
Single-ended: 0V to 1.5V / differential:±1.5V
• FTP Push
• FTP+TLS Secure Push
The flexible Lua scripting engine has full control to accept or collect sample data from serial | ModBus | SDI-12 | Analogue/pulse.
Data can be calculated and formatted in any ASCII (e.g. CSV, XML, JSON, etc.) or binary format, and any alarm conditions can be detected.
It also provides full control over delivery schedules and triggers.
Configuration and Setup
Configuration and administration of the EnviroLog 4G:
• USB on Windows (no driver needed)
• Over the air with IoT server
• Over the air with Terminal (ToA) access
Connected devices can be configured locally, or remotely, with full pass-through facilities.
128MB of non-volatile flash memory - up to 2 000 000 data points (chip-on-board for maximum reliability)
The Terminal Over the Air mechanism connects a TCP/TLS socket to an Internet server and provides a full remote link to the EnviroLog 4G’s terminal interface.
Remote Management & Update
Can be controlled through the IoT server for:
• Firmware and Lua App upgrades
• Configuration changes
• Diagnostic requests
• Executing arbitrary Lua code
(e.g. to control and reconfigure connected devices)
Data Transmission - 4G
Daughter-board PCBs for RS485/Power Output controls
Can run from internal batteries and/or external DC supply:
• Souriau UTS HiSeal
• FCC 47 CFR Part 15B -USA
• ICES-3 (B) /NMB-3 (B)-Canada
• CE RE Directive 2014/53/EU-Europe
