4-channel universal counter module with sensor excitation and adjustable trigger-thresholds

February 27, 2013 // By Julien Happich
Ipetronik's business division IPEmeasure has extended the second generation of its CAN- measurement modules of M-Series to a four channel universal counter module with sensor excitation and adjustable trigger thresholds.

M-CNT2 supports all measurement functions of the reliable M-FRQ; however, it now provides detection of rotational direction, event counting and in conjunction with the detection of rotational direction the up- and down counting. Each channel can be separately activated and scaled. All the measurement inputs, sensor excitation and the CAN-Buses are completely and electrically isolated amongst each other.

The universal-counter module supports frequency measurements in a range of 0.03 Hz to 200 kHz and period duration measurements from 1 microsecond to 200s. It offers four separated and voltage selectable sensor supplies, one per channel, with a maximum supply of 15 V and up to 60 mA. The trigger thresholds are selectable in a range of ±40 V, whereby the maximum input voltage should not exceed ±100 V (Nominal voltage) or ±500 V (peak voltage). The module supports channel-sampling rates from 1, 2, 5, 10, 50, 100, 200, 500, 1000, 2000 as well as 5000 Hz. Status-LEDs at each measurement input indicate the correct signal evaluation. The data output interface is a CAN-2.0B-Bus according to ISO 11898-2 with up to 1 MBit/s. Measurement data can be provided in a per channel selectable resolution of 8 Bit (Byte) or 16 Bit (word) signed or unsigned. All the settings can conveniently be done using the manufacturer’s data acquisition software IPEmotion.
The M-CNT2 module is certified according to protection class IP67 and operates in a temperature range of -40 °C to +125 °C.
