Overview
The EnviroHub Control Module (CM02) is an affordable cutting edge industrial programmable logic controller with specialised capabilities for use with EnviroHub systems.
Quick and easy to set up, it can be configured for a large array of water monitoring and control purposes and is capable of returning quality data to the Senteos portal, for graphical display.
Benefits of the CM02
- Speed of setup – modular
- Easy to setup – no technical experience required
- Cost versus a bespoke PLC – the CM02 is a fraction of the price
- Quality of reporting
- Remote access reduces service engineer miles
General
The CM02 is a modular plug-and-play system comprising of a central core board and individual CM02 ‘Cards’. The core board houses a series of ‘sockets’ that CM02 ‘Cards’ can plug into. Up to 15 Cards can be inserted into any one Core Board, giving the potential for a wide array of inputs and outputs, for monitoring and control.
Each individual Card is for a specific type of input e.g. power, sensor or for an output e.g. relay to control a pump and as many Cards as required can be added to a Core Board, up to the maximum of 15.
The CM02 is completely reconfigurable (which makes it very attractive for specialist hire companies) as the asset can be redeployed for another application simply by changing the cards plugged into the Core Board. Cards can be inserted into any socket within the Core Board, which automatically identifies which Card has been plugged in, to minimise the chance of operator error. For fixed installations, this also means it is much more cost effective to add additional sensors as another card can simply be added to the Core Board.
The main enclosure is rated to IP67 and space within this is maximised as no cables are terminated into the Core Board itself. Rather, cables are terminated into the respective Card and this is then plugged into the Core Board. This makes it much easier to ensure that cables have been terminated correctly and that a firm connection has been established.
The CM02 has also been developed with Low Power Consumption in mind, making it energy efficient and allowing solar power to be an affordable option.
CM02 Cards
Each card is fully self-contained to carry out its functions with no additional wiring or programming required by the end user. There are several different types of CM02 Card available which have the typical functions listed below (not exhaustive):
- Power (24V as standard, others available)
- Telemetry: (4G connection to Senteos Portal for monitoring and control)
- Water Quality Parameters e.g. Flow, Turbidity, pH, Temperature, Dissolved Oxygen
- Switch Inputs e.g. float switches, level switches
- Switch Outputs e.g. pump On/Off
- Dosing Pump Controls
- Ultrasonic level sensors (refer to CM02 Card Technical Data Sheets for specific compatibilities)
New cards are continually being created to accept sensors across a broad range of communication methods e.g. analogue, digital, 4-20mA, 0-10V, Modbus, RS485.
Using the CM02
Site Engineer
Sensor calibration and CM02 configuration is extremely simple thanks to the EnviroHub App, available on Google Playstore (Android only). Remote connection via Bluetooth makes functions like sensor calibration a very simple operation for when in the field and exposed to inclement weather. An audible signal and digital screen on the Core Board provide real-time feedback on set-up and calibration operations.
End User
End Users can access data from the CM02 via the Senteos Portal, which displays reported information in a graphical format. Graphs can be configured to show discharge limits (hard limits) and safety margins (soft limits). The CM02 can intervene when a soft limit is breached, to send an email and text message alert. This enables site personnel to take action to prevent the discharge limit being reached. The CM02 can also control discharge pumps and valves, via suitable Output Cards, to ensure that only water within limits is discharged or passed through the systemd.
Warranty
Warranty of hardware is 3 years from the date of purchase, please refer to CM02 Card Technical Data Sheets for specific details.
