Contrec 202D User Manual page 6

The following improvements have been made in the Model 202D:
Ÿ The 202D output board can have both ALARMS and a 4-20mA OUTPUT.
Ÿ The voltage drop across the alarm outputs in the 202D is ONLY 0.8 VOLTS.
Ÿ The voltage supply for the DC and loop powered versions can go AS LOW
AS 9 VOLTS.
Ÿ The 202D has an overall LOWER CURRENT CONSUMPTION than the
previous model with an IMPROVED BATTERY LIFE - the battery life in
the new model is typically 5 years regardless of the time the unit
spends in totalising mode.
Ÿ In the 4-20mA output version of the 202D, the ACCURACY HAS BEEN
IMPROVED to 0.05% of span and the linearity to 0.05% of span at
25°C.
Ÿ The millivolt input can accept signals AS LOW AS 15mV P-P.
Ÿ The 202D has a WIDE FREQUENCY RANGE - 0.01Hz to 10kHz.
Ÿ The 202D has a WIDER K-FACTOR RANGE - K-factors from 0.000001 to
999,999 can be programmed.
Ÿ Flowmeter Linearisation up to 10 points is now standard.
Ÿ Unlike the previous Model 202, the 202D has an additional mounting
option - it is available in a PANEL MOUNT version.
