Micro processor based universal Timer / counter
Libratherm offers model UTC-400 a general purpose microprocessor based real time digital universal timer / counter for industrial use. This Real Time Based timer / counter is designed to serve the special purpose application which ordinary timer or counter can not easily meet. Multiple timer and counting facility allows single unit to perform multiple functions.
For timer functions - the On delay/OFF delay /Cyclic modes are user programmable with maximum 4 event outputs in the form of relay contacts. The real time clock is also available for the real time dependent event outputs. Any complex time based applications can be programmed through front panel key board.
For counter functions the unit accepts inputs from the proximity sensor, photo sensor or a mechanical contact. Up or down counting with programmable multiple set point makes unit versatile for any counting applications.
The counter / timer has 8 digit display to indicate time or count values with 4 keys for programming various functions.
The Timer operates on 230V / 110 VAC, 50 / 60 Hz and is protected against industrial RFI/EMI interference by a suitable filter. It requires a standard DIN panel cut out of 92 x 92 mm.

Digital Timers / Counters / Stop watch/ RPM Meters
Libratherm offers simple Digital timers/counters for general purpose industrial use. The timers are accurate, rugged, reliable and field proven and based on solid state electronic design. The accurate time base ranging from 0.01 second to 1 hour is derived from high frequency quartz crystal oscillator. The delayed ON, delayed OFF and Cyclic mode of operations are available with the output of single or dual relay change over contacts rated for 5A @ 230VAC. The desired time can be preset using the front panel push button coded wheels. The elapsed or remaining time is displayed on 2 to 4 digit bright red or green LED display.
The timers with stop watch function having front panel RESET and START/STOP switch is also available with and without PRESET facility. Battery back up features are also optionally available. The timer operates on 230 VAC or 110VAC or 24VDC supply. They are available in various sizes of 96 x 96 x 120, 96 x 48 x 130 , 48 x 96 x 130 or 72 x 72 x 110 mm.
The counters are designed to accepts proximity sensor or photo sensor or mechanical contact to count objects or events. The desired count value can be set using the push button coded wheels and the relay output is available when the count value equals the set value. The RPM meter also accepts proximity sensor or photo sensor and accurately measures RPM in the range of 6 to 10000 RPM of any rotating objects.

Features

Quartz Crystal Time Base 0.01, 0.1, 1 sec/min/hour

On Delay, Off Delay and Cyclic mode of operation

Proximity, Limit switch, Photo sensor etc. inputs for counter

DIN and 1/8 DIN Sizes sturdy metal enclosures

Remote and front panel start/stop

Operates on 230VAC/110VA
Applications :

The timers/ counters have wide industrial applications, where time and count (numerical value) dependent event control is required. For example to start and stop the machine or to activate the solenoid valve on reaching the count value etc.
