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.
