T-BOX LP200

The LP200 has digital inputs plus several analog features as well.

Semaphore offers the low-power LP200 RTU that is able to operate in environments where there is no power supply. With extremely low power consumption, the LP200 can operate on batteries for up to 10 years without any maintenance. The LP200 has digital inputs plus several analog features as well. It operates on a standard PSTN communication line. Data are collected and stored into memory. The system dials up for database uploads or when alarms occur.

The LP200’s technical specifications are as follows:

Low power datalogger and remote alarming system
8 digital inputs dry contacts (0 to 12V compatible) for counting and flow measurement. Acquisition frequency: 8 times per second.
Maximum input voltage: 30 VDC
3 analog inputs 10 bits that can accept:

External pressure sensor: power supply 12V or 24V measurement 0-5V
0-5V with power supply 12V or 24V delivered during the time of the measurement (programmable)
4-20mA with power supply 12V or 24V delivered during the time of the measurement (programmable)

1 analog input 10 bits for voltage measurement -10 to +10V (i.e. cathodic protection).
