Monitoring of analog values

Full insight in the voltage trend and notifications in the event of deviations


Mobeye CM-Guard TwinLog

The Mobeye CM-Guard TwinLog (CML4055) is a voltage monitor, ideal for use as a batteryguard. In an alarm situation, it sends notifications via push message, call, SMS or e-mail. It also logs the analog values and sends them to an online portal for visualisation as a graph, gauge or table.

Monitors the upper or lower limit
for pre-set analog values.

Complete and user friendly voltage monitor with alarm and log functions. For reliable monitoring of the analog values and sensors You can prevent damage by timely intervention.

This product is the successor of the Mobeye CML2055.

Measurement of analog values

The inputs are suitable for measuring analog values between 0V and 48V, with peaks up to 64V. The alarm limits are adjustable in decimal precision.
The interval for logging the values and transfer to the portal are adjustable.

Alarm messages

In the event of an alarm, the Mobeye CML4055 sends alarm notifications by app (IOS/Android), telephone call (voice message), text message and/or e-mail. The message includes the actual value. For the push messages there is a choice between an escalation plan or group message. With the escalation plan, the recipient can confirm the push message, so that the other contacts no longer receive the message. If none of the recipients confirms the push message, a phone call is made. The number of contacts is unlimited.

External voltage vs battery powered

The Mobeye CML4055 can run on its internal batteries for a long time which makes it independent of an external power source. If an external power source is available, it is recommended to connect it. The availabiltity of the power supply is then monitored. it will also send power failure alarms. If there is outage, a notification follows. The batteries take over and the CML4055 will continue to monitor and send alarm messages. Once the power restores a notification will be sent. The batteries are included in the standard product. A country-specific mains adapter is available as accessory.

Alarm inputs, piezo siren and open collector output

The Mobeye CML4055 has two inputs. Both are suitable for analog measurement (AN) or for a normally open (NO) or normally closed (NC) contact. In the event of an alarm an audible alarm indication can sound by the internal piezo siren. In addition to this an (open collector) output is available to switch an external device.

Network and SIM card

The Mobeye SIM card gives the device full functionality, including the use of the Mobeye Internet Portal and the app. With the Mobeye SIM card, communication takes place over the 4G LTE-M network with 2G as fallback. It then provides the log function. The voltage trend and status are displayed in the portal.
When you insert your own SIM card, the device works on 2G. Logging is not possible, alarm messages are then sent via SMS and/or call to max. 5 telephone numbers.
