Fully programmable PID or ON/OFF
with adjustable hysteresis as configured by the user.
Active Tuning and Self Tuning
In addition to self tuning the
SA100 also features continuous active tuning. Active
tuning which can be manually selected, automatically
adjusts PID values as a result of a process change, to
ensure optimum performance.
Either of the specified outputs
may be configured by the user to act as deviation or
One alarm may be configured by the
user to detect a fault in the control loop caused by
failure of the heater element, load relay or sensor
A wide range of thermocouple and
resistance thermometer inputs can be specified.
Current and voltage inputs are also available.
Relay, SSR and current (0-20mA or
4-20mA) outputs are available and may be easily
configured by the user for control, retransmission or
Panel or DIN Rail Mounting
The SA100 may be panel mounted
(panel thickness 1-10mm) or it can be fitted to a DIN
rail using the optional base terminal connector (see
accessories box below for code numbers for this
RS485 communication is available
as ANSI Serial code or Modbus protocol allowing the
SA100 to be connected to PCs and PLCs. Up to 32
instruments can be connected to a single communication
Heating/Cooling Control Action
In applications where the process
generates heat, the use of heat/cool PID contributes to
stable control and energy savings. The controller
allows the selection of an overlap or deadband between
the heating and cooling outputs. Heating/Cooling
Control action is available with self tuning. A choice
of control signals is available for both heating and
Waterproof and Dustproof Version
An IP66 version of the SA100 is
Process Value Bias
This option allows the measured
object temperature to be offset on the display to
compensate for errors due to difficulties in correct
placement of the sensor.
Non volatile memory and set data
lock prevents loss or inadvertent change of data due to
power failure or incorrect operation.
A digital input contact is
available for either setpoint 1 or 2 switching or run /
stop control. This function can be used with the output
from a timer, PLC, etc.
Control Output 1 may be specified
for retransmission of Set, Process, Deviation or
Control output variables.
Programmable Panel Display
When used as an indicator only
(with or without alarm outputs) the set value display
may be turned off to avoid confusion.
A choice of 85/264V AC or 24V
AC/DC supplies is available.
