Description
| Typically used in applications involving
speed, the S661 rate counter is capable of counting in four different
time modes: hours, seconds, and seconds/thousand (msec). The msec
rate mode increases the frequency resolution to .001Hz within the
range from 1 to 999.999Hz. The S661 is compactly designed and features
a standard 1/8 DIN case made of PBT-ABS alloy. Screw terminals are
standard for easy installation and removal of the meter. The counter
is powered from 120 or 240VAC and has a non-volatile EEPROM to retain
all programming and count information when the power source is removed
or interrupted. An optional 12VDC (100mA) excitation output module
can provide power for external sensors. Optional field-replaceable
signal/dual relay modules enhance the counter from a passive display
device to an integral control element for your application. This
versatile counter has latching, boundary or timed (0.01 to 599.99
seconds) output modes. |
