The CN74000 Series controllers set a new standard in
1/32 DIN power, flexibility, and value. Despite their small
size, these controllers are loaded with features,
including multiple universal inputs, fuzzy logic,
autotune, auto/manual capability, and 16-segment ramp
and soak with adjustable time base. RS485 serial
communication is optional.

Note: All thermocouple and RTD inputs can be set for 0.1° display.
If temperature goes above 999.9° or less than -199.9° the display
will return to whole degree resolution.
* Process Input Types: The 0 to 20 mAdc, 4 to 20 mAdc, 0 to 10 Vdc,
and 2 to 10 Vdc, inputs are fully scalable from a minimum of
100 counts span placed anywhere within the within the range of
-1999 to 9999. Decimal point position is adjustable from the zero place
(9999), tenths (999.9), hundredths (99.99), or thousandths (9.999). |
