6Important notes for using the MAL-UI
•The MAL-UI is only suitable for extra-low voltages - please observe the relevant regulations!
•Only use an electrical isolated power supply unit (with CE).
•Turn off the power before mounting the module onto the carrier board.
•All accessible pins are electrostatic sensitive devices. Provide for a grounded conductive work place.
•MAL-UI must only be operated in closed housings (for reasons relating to EMC).
•Only use non-solvent detergents for cleaning. The product is designed to be maintenance-free.
•The module must not be used for safety-relevant tasks. With the use of the product, the customer becomes manu-
facturer by law and is therefore fully responsible for the proper installation and use of the product. In the case of
improper use and/or unauthorized interference, our warranty ceases and any warranty claim is excluded.
Do not dispose of the product in the domestic waste or at any waste collection places. It has to be either duly dis-
posed according to the WEEE directive or can be returned to bmcm at your own expense.
7Technical data
(typical at 20°C, after 5min., +7.5V supply)
•Input range
Measuring range DC: ±10V (close PL12, ex works), ±5V (close PL11), ±1V (close PL10) or 20mA (close PL5 + PL10)
Gain calibration at // Input resistance diff.: +10V // 300kΩ(for U) or 50Ω(for I)
Input suppressor circuit for 1sec: max. 200V (not in case of current measurement)
•Output range
Output voltage: ±5V DC
Output load: >1kΩ; recommended for higher accuracy: >10kΩ
Amplifier accuracy // Temperature drift: typ. 0.2% // 50ppm/°C
Output interference or output ripple: typ. 5mVss at app. 100kHz (from DC/DC converter of the backplane)
Current supply sensitivity: typ. ±10mV/V
Output filter // Filter cut-off frequency fg: 1-pole (6dB/oct.) // 2-340Hz (configurable with solder bridges PL8 + PL9)
The values for accuracy always relate to the respective measuring range. Errors might add at worst.
