Description
The EOMC is a single-channel IO-Link transducer as an OEM board, type MCUT-E.
It converts the signal from a full strain gauge bridge into a digital measured value – for force and pressure. The measuring range is freely adjustable and unitless: the board adopts the unit of the application, whether Newton, kilogram, or bar. Since the value is transmitted via IO-Link, configuration, diagnosis, and device replacement are possible without recalibration.
The channel accepts 1 × full strain gauge bridge from 350 Ω, with two parallel full bridges at least 2 × 700 Ω; further bridges are possible, the minimum resistance increases accordingly. The bridge supply provides 3 V. The measuring range is freely adjustable in the range of -3200.0 … +3200.0. The resolution is 16 bit, the accuracy is max. 0.05 % of the measuring range plus sensor error. The filter is 0.5 s, the power-on delay is less than 5 s, and the response time is 20 ms.
The output has an IO-Link interface with a signal level of 0 / 24 V according to IO-Link specification. The board is powered with 24 VDC at less than 30 mA in standard operation, a maximum total current of 130 mA; the switching current in SIO mode is a maximum of 100 mA. Polarity reversal is protected – no function, no destruction.
The board measures 40 × 17 × 4.5 mm and weighs approximately 6.5 g, material FR4 and PBT, connection via solder pads 2.7 × 1.5 mm, mounting position arbitrary. The operating range is from -20 °C to +80 °C, the storage temperature from -20 °C to +85 °C.
An IO-Link master is required for configuration and operation, as well as the appropriate IODD file from the IODD Finder. The board has IP00 and must be installed in a housing. It has been tested according to EN 61000-6-2:2005 and EN 61000-6-4:2007 + A1:2011. A CE mark is not documented in the manufacturer's data sheet, a declaration of conformity must be requested before placing it on the market in the EU. This board has one channel and no temperature input; the two-channel version with a universal channel is the EOME, the round design is the EOMD.
Regarding the price: The price applies to the board in its basic configuration. The measuring range is freely adjustable via IO-Link, so factory programming is not required. If you still wish to have the board factory programmed to your measuring range, this is possible at an extra charge — please ask us about it.
