Designed for equipment manufacturers requiring analog
process control functions and a full suite of advanced features, the
7SC offers outstanding performance as a 4-digit 1/8 DIN controller.
The 7SC is configurable for heat or heat/cool PID control with Smart
AT auto or adaptive tuning, universal inputs, up to 4 outputs (including
one analog output) and up to 3 independent alarms. It is ideal for
demanding applications in plastics, rubber fibers, annealing, small
ovens, and other processes requiring 4 digit accuracy. The 7SC has
a bright dual display for process temperature and setpoint, and 10
LED beacons for operating status. The analog and two relay outputs
can be programmed as heating +2 alarms or heating/cooling + alarm.

Alternately, OP2 can be an
SSR logic output. The isolated analog output can alternatively be
programmed as a retransmission of the PV or operating SP. OP4 can
be configured as Alarm 3. Alarms can be process, deviation or band
type, direct or reverse, with masking and programmable automatic or
manual reset. An alarm standby feature allows masking of alarm conditions
until the PV reaches the low alarm threshold. A non-isolated 24 Vdc
transducer power supply is a standard feature. Optional RS-485 communications
are available for connection to supervisory computers. A NEMA 4X front
panel allow the 7SC to work in washdown or dusty environments. |

| Among the 7EC's
standard features are bumpless auto/manual transfer, password security
and Auto Comp® sensor break. The 7EC also has an "output off"
function which disables the control output, allowing the instrument
to operate as an indicator but return smoothly to control when the
output is again enabled. The 7EC is equipped with 2 logic inputs used
to select between up to 4 setpoints. Transfer can be step or ramp,
with different configurable rates for ramp up and ramp down. |
