1 Product Description
1.1
General Description
The S660 preset counter fits a 1/8 DIN standard cutout and is perfect for tight spaces, extending
only 3.24" (82mm) behind the panel. The unit is UL listed. The unit is for indoor use at altitudes
up to 2000m, temperatures between 0° and 40°C, and installation category III, pollution degree
2.
The counter is powered from 120 or 240 VAC. The nonvolatile EEPROM retains all programming
and count information when power is removed or interrupted.
Display scaling, preset values and all menu functions are easily programmed from the front
panel, following easy-to-use word prompts. Front Panel Reset Disable and Password Lockout
Protection features guard against unauthorized or accidental changes.
The counter accepts count rates up to 20 KHz and pulses from different types of sensors,
including Quadrature, CMOS or TTL circuits and PNP or NPN devices.
The optional, field-replaceable, single/dual relay module enhances the counter from a passive
display device to an integral control element for your application. Outputs may be controlled by
count values with independent reset operation. The counter has latching, boundary or timed
(0.01 to 599.99 seconds) alarm output modes. An optional 12 VDC (100mA) excitation output
module can provide power for external sensors.
