In addition to the features of the TME400-VC, this version can be used for cus-
tody-transfer applications.
Power supply

Battery-operated device
The TME400 is equipped with a replaceable 3.6 V lithium battery. The device is de-
signed for continuous operation for approximately 10 years. To achieve this, the de-
vices may be operated for a maximum of 15 minutes per day with input pulses of
1 Hz.
Battery-operated device with additional external power supply
An electric supply of the TME400 via the 4-20mA current loop reduces the power
consumption from the batterie and typically extends the service life of the battery to
more than 12 years.
If the TME400 is additionally electrical powered by the RS-485 interface, the service
life of the battery is typically extended to clearly more than 12 years.
