The BATRT-M uses the 4-20 mA loop power as its primary pow-
for standby battery operation.
Setup Information: Stored in fl ash memory
Totalizer: Stored in battery backed RAM but can be saved to fl ash
This option enables you to access a variety of process parameters
through serial communications. PC compatible communications soft-
ware is included with this option. With this software and a BAT R/T-M
through your PC.
The optional RS-485 card utilizes Modbus RTU protocol to access a
variety of process parameters. The Data Logger stores the totalizer
to fl ash memory once every 24 hours at the time you set. The data
the logger is dropped. Requires external DC power: 6-28VDC (input is
