LINEARIZATION
Thermocouple and RTD inputs are automatically linearized.
Transmitter inputs may be linearized with a square root function or
user-defineable 15-point straight line linearization function.
INPUT IMPEDANCE
Current Input:
250 ohms
Thermocouples:
10 Mohms
Voltage Input:
1 Mohms
RTDs:
10 Mohms
UPDATE RATE
Input is sampled and output updated 10 times per second. Display
is updated five times per second.
TRANSMITTER LOOP POWER
Isolated 24 Vdc (nominal) loop power supply is available if a loop power
module is installed in an output socket not used for control. Capacity is
25 mA.
INPUT SIGNAL FAILURE PROTECTION
When input is lost, output is commanded to a predetermined
output (–5 to 105%). Thermocouple burnout is selectable for
upscale or downscale.
INPUT FILTER
Single pole lowpass digital filter with selectable time constant from
0 to 120 seconds.
CALIBRATION
Comes fully calibrated from the factory and continuously
calibrates itself for component aging due to temperature and
time, except for the reference voltage. Field calibration can be
easily performed in the field with a precision multimeter and
thermocouple simulator. Process variable offset and gain factors
are provided to correct for sensor errors.
OUTPUT MODULES
The controller can have a total of four control outputs, alarm
outputs and/or loop power modules installed. There are five
types of output modules which can be configured to suit your
particular application. The modules may be ordered factory-
installed, or they may be installed in the field.
Analog module:
Either 0–20 mA or 4–20 mA (front panel select-
able) into a load up to 1000ohms. Accuracy ± 5µA @ 25°C.
Mechanical relay module:
SPDT electromechanical relay. Resistive
load rated at 5 amps at 120/240 VAC. Normally open or normally
closed selection is made by jumper. Output 4 is rated at 0.5
amps at 24 VAC and is always normally open.
Solid state relay (triac) module:
Resistive load rated at 1 amp at
120/240 VAC. Output 4 is rated at 0.5 amps at 24 VAC. These
outputs are normally open.
DC logic (SSR drive) module:
“ON” voltage is 17 Vdc (nominal).
“OFF” voltage is less than 0.5 Vdc. (Current limited to 40mA.)
Loop power supply module:
Current is limited to 25 mA @ 24V
(nominally loading).
CONTROL OUTPUTS
Up to two output modules may be designated for control. Any
combination of output modules, with the exception of the loop
power supply module, may be used.
