Four channel analogue input module adds direct CAN bus output

May 23, 2013 // By Nick Flaherty
German test equipment maker IPEtronik has upgraded its M-Series by adding a 4-channel analogue input module with direct CAN (Controller Area Network) bus output.

The new M-SENS2 module is compatible with the previous M-SENS and provides the same type and number of measurement ranges. By adding a higher internal sample rate and the newly designed 500 Hz hardware filter it now supports higher input frequencies.
M-SENS2 covers twelve unipolar and twelve bipolar voltage measurement ranges from ±0.1 V to ±100 V. All inputs also support the often used 0 to 20 mA or ±20 mA current input without adding external hardware. Each input provides a selectable sensor excitation of up to 15 VDC and a maximum supply current of 60 mA. Measurement inputs, sensor excitation, CAN bus and power supply are completely galvanically isolated from each other. The output data is transmitted using CAN bus 2.0B the automotive standard according to ISO 11898-2 with up to 1 MBit/s. All configuration settings can be set up conveniently using IPEmotion, IPEtronik's configuration and data acquisition software.
The redesigned M2-Series enclosure uses dimensions of 106 x 43 x 60 mm (WxHxD) and can be connected to each other without any tools. All M2-Devices are designed for use in the engine compartment supporting IP67 protection class, as well as the extended temperature range of –40 °C to +125 °C. A supply voltage in the range of 9 VDC to 36 VDC is required: the module still works down to the lower limit of 6 VDC once powered up. Typical power consumption is 3.0 W.
