modularly organized, which are combined as channels, able to meet

present and future instrumentation requirements.

Channel(s) provide for value measurements and quantity accumulation,

rate measurements, scalar measurements, supported by value scaling for

process voltage and current process signals. Signal acquisition uses digital

signal processing rejecting ambient noise and interference.

1-1-2 Communication

The communication facilities provide for data acquisition, command, and

control functions, supporting configuration programming and information

gathering.

Communication is initiated by command (solicited), alarms (unsolicited) &

real time scheduled reporting using its internal date-time clock.

1-1-3 Process Controls

Totalizer, batch, and proportional blending (0254 only) are readily achieved

using the front panel key controls or serial commands.
