To Order Model CN77000 SERIES CONTROLLER (Specify Model Number)
PROCESS CONTROLLER, DUAL DISPLAY FOR THERMOCOUPLE, RTD, VOLTAGE OR CURRENT INPUTS IN A 1/16 DIN CASE
Model No. Description
CN77 Dual displays for simultaneous display of measured value and setpoint.
Selectable preset tune, adaptive tune, autotune, PID, PI, PD control modes. The
dual control outputs can be configured for a variety of control and alarm
applications such as heat, heat/cool, heat/alarm, cool or cool/alarm. The ramp to
setpoint feature allows the user to define the rate of rise to setpoint, minimizing
thermal shock to the load during start-up. Maximum ramp time 99.59 (HH.MM),
Soak: 00.00 to 99.59 (HH.MM),Damping: 1 to 8 in unit steps. Input types
J,K,T,E,R,S,B,N,J-DIN¡C, RTD 100½ 0.00385, 100½ & 1k½ 0.00392, 0 to 20 mA,
4 to 20 mA, 0 to 100mV, 0 to 1V, 0 to 10Vdc. Alarm 1 output includes SPST relay,
3A @ 120Vac, 3A @ 240Vac.
NOTE: The Controller must be ordered completely configured. Options are not field installable.

NEMA 1/UL Type 1: Intended for indoor use, to provide a degree of
protection against contact with the enclosed equiptment and against
limited amount of falling dirt.
NEMA 4/UL Type 4: Intended for indoor use, to provide a degree of
protection against splashing water, windblown dust and rain, and hose
directed water and undamaged by the formulation of ice on the enclosure.
Testing-Hosedown: Enclosure is subjected to a stream of water from a
hose which has a 1" diameter nozzle and which delivers at least 65 gallons
per minute from a distance of 10 to 12 feet for a minimum of 5 minutes.
NEMA 12/UL Type 12: Intended for indoor use, to provide a degree of
protection against circulating dust, falling dirt, and dripping non-corrosive
liquids. Testing-Drip: Enclosure is subjected to a drip pan which produces
both splashing and dripping. Testing-Atomized Water: Enclosure is
subjected to a spray of atomized water by using a nozzle that produces a
3" round diameter spray, 12" from enclosure. The air pressure is at 30psi.
For harsh environments, we recommend installation of the controller for
square panel cutouts.
