Mobeye CM-Guard TwinLog CML4055 – Voltage Monitor & Alarm
The Mobeye CM-Guard TwinLog CML4055 is a compact instrument designed for precise monitoring of analogue values, ideal for use as a batteryguard. Equipped with two input channels capable of measuring values ranging from 0V to 48V, it excels as a battery monitor. When the voltage from a connected battery or sensor exceeds preset limits, the device triggers an alarm notification and logs the measured values for convenient access via the online portal. The CML4055 can operate solely on battery power or with external power support, providing flexibility for various applications. Its built-in communication module offers compatibility with both 4G LTE-M and 2G networks.
Alarm Notifications and Logging
In the event of an alarm, the Mobeye CML4055 offers versatile notification options, including app alerts (the Mobeye Messages App is available for both iOS and Android), telephone call notifications with voice messages, text messages, and email alerts. Multiple contact persons can be configured to receive customised alarm messages. The device’s log functionality is accessible through the Mobeye Internet Portal, where logged values are sent periodically and after an alarm, displayed in a clear table format and as graphical representations.
The Mobeye CML4055 can run for over a year on a single set of batteries. When using an external power source (12-24V DC or mains), it also sends “power failure” notifications.
Flexible Inputs and Output Control
The Mobeye CML4055 features two inputs suitable for analogue measurement (AN) as well as normally open (NO) or normally closed (NC) contacts. In case of an alarm, an internal piezo siren can sound as an audible indication. Additionally, the CML4055 provides an open collector output that allows control of external devices.
Battery Monitoring System, Voltage Alarm, Batteryguard
The CML4055 serves as an efficient 4G battery monitoring system aimed at preventing damage. It aids in identifying deep discharges, a common cause of battery malfunction, by triggering alarms when voltage levels deviate from preset limits. Moreover, it offers an open collector output that can activate the switching of a battery or device in response to critical conditions.
How it Works
The Mobeye CML4055 monitors the voltage value of a connected battery or analogue sensor. It continuously measures the values to immediately alarm in the event of deviations and to log these periodically.
- Connect a battery or analogue sensor to one of the inputs.
- Set the minimum and maximum analogue limits, log frequency, and designate contacts for notifications.
- If the voltage falls below or exceeds the set thresholds, the CML4055 sends alarm messages to designated contacts. Voltage trends can be conveniently monitored online through tables and graphs.
Typical Applications for the Mobeye CM-Guard TwinLog CML4055
The Mobeye CM-Guard TwinLog CML4055 is a versatile voltage monitor and alarm system designed for accurate battery and electrical system monitoring. It provides instant alerts when voltage levels fall outside safe ranges, helping prevent equipment failure and ensuring reliable operation. Its remote monitoring capabilities make it suitable for a wide range of professional and personal applications.
Common applications of the Mobeye CM-Guard TwinLog CML4055 include:
- Aggregates and generators, monitoring battery voltage to ensure continuous power supply and acting as a backup for secondary systems
- Rental equipment, allowing companies to track battery usage and maintain operational readiness
- Boats and marine applications, giving owners peace of mind that the battery is fully operational while they enjoy their day off
- Battery maintenance, helping battery owners avoid over-draining and prolong battery life
