They are used for counting cycles, turns, product quantity and so on, in the automation process. Device uses micro controllers, which allows great adaptability to specific needs. It is possible to count up or down, setting the number of pieces on the front panel keys. Current value is visible on the LED display. Push button or various types of probes: inductive, capacitive, optical switches, optocouplers can be used for counter input. Relay output becomes active for a period of approximately 2s after reaching the given criteria and then relay releases, counter automatically offers to start over. Upon request other versions are possible (manual reset, relay activity for a prolonged period (more than 2s), etc.).
-power supply: 230V AC or 24Vdc
-consumption: around 2VA
-input: potential-free contact, normally open (or specify the type of sensor)
-contact rating: 5A/230Vac
-preset and actual value saved in case of power failure
-housing: panel mounting 96x48x75mm (93x45mm mounting hole)
TACHOMETER WITH DISPLAY AND RELAY OUTPUT
Tachometer is a micro controller unit which performs the measurement and control of speed. Can be used to display speed, detecting that the drive has reached a speed or stopped. The unit has a relay output, which is activated when the set point is reached. Limits is set via keys on the front panel and four digit LED display. For the tachometer input various kinds of probes can be used: inductive, capacitive or optical switches.
Basic features:
-power supply: 230Vac or 12Vdc
-consumption: around 2VA
-contact rating: 5A/230Vac
-measurements: three ranges (with auto range) 3-99.9 rev/ min, 100-999 rev/ min; 1000-9990 rev/ min
-resolution :0.1-10 rev/min depending on the measuring range
-accuracy: 1%
-set values saved in case of power failure
-housing: for panel mounting 96x48x68mm (93x45mm mounting hole)
TACHOMETER WITH RELAY OR CURRENT OUTPUT
It is used to control motors, conveyor belts and so on. Drive speed information is obtained using an inductive switch. When speed falls below set value output relay releases and that can be used as alarm or as shutdown command for motor .
Instead of relay output you can use version with standard current output 0-20mA directly proportional to the number of revolutions per minute.
The device is built into the casing with IP65 degree of protection which allows use in harsh industrial environments or plugable case.
It is used to display frequency of voltage which is applied as a supply (line voltage or voltage generated by automotive generator).
Basic features:
-power supply: 230Vac
-consumption: 2VA
-display: LED display 3 digit (50.0Hz)
-housing: for panel mounting
-for versions with relay output you can set two thresholds at which output responds
They are used to display voltage, current, or a non-electrical value which is converted into a voltage or current (temperature, pressure, level .... converted to standard voltage or current signals 0...4... 20mA, 0-10V, 0...60 mV ac / dc from shunt). The main input voltage ranges are 200 mV and 2Vdc although any value of voltage can be used. Calibration potentiometers inside the instrument set zero and maximum of the scale. The display is LED with 3 1/2 digits or 4 1/2 digits. Instruments have their own power supply (230 Vac), galvanically separated from the measured signal. Housing for panel mounting dimensions 96x48x68mm (WxHxD). Cut out is 93x45mm. We can make instruments with higher figures for better visibility from a distance and installation can be in the housing with a high degree of protection (IP65) if it is required by ambient conditions.
