Notes
The MGCplus system is tested in accordance with the harmonized European standards 61326-1:2013 and
61010-1:2010. It therefore conforms to the applicable directives 2014/30/EU (Electromagnetic compatibility, EMC)
and 2014/35/EU (Low-voltage electrical equipment) in relation to protection against hazards. Mechanical stress is
tested in accordance with European standards EN 60068-2-6 for vibration and EN 60068-2-27 for shock. The
devices are exposed to an acceleration of 25 m/s2 within the frequency range 5...65 Hz in all 3 axes. Duration of
this vibration test: 30 minutes per axis. The shock test is implemented at a nominal acceleration of 200 m/s2 for a
duration of 11 ms, half sine and with shocks in each of the six possible directions. The maximum load per MGCplus
slot is 150 mA with 16 slots. Double slot loading is possible if an adjoining slot is left vacant.

4) Accuracy class and absolute zero error for voltage measurement only
5) A maximum of 1 A may be drawn from the MGCplus to supply the transducer.
6) 100 m max. distance between connection board and T-ID/TEDS module
7) The number of subchannels can be changed via the MGCplus Setup Assistant or the MGCplus Firmware Loader.
8) From AP809: Hardware revision 3.00
9) The total error limit for thermocouple type N is ±2 K
10) In industrial electromagnetic environments under the influence of continuous disturbance variables, the total error limit is ±1.5 K.
11) ML801B/AP801 resp. AP801S6: The 1000 Hz Butterworth filter is only supported as from the AP801/AP801S6 hardware version 1.20.
12) Internally, the signals are converted independently of the preset number of subchannels at 38.4 kHz. The implementation of a digital filter
calls for a reduction in the sampling rate (through repeated averaging and sub-sampling). This reduced sampling rate is called the "internal
sampling rate".

*) If the transducer cable is laid outside enclosed rooms, or with cable lengths of more than 30 meters between the connection board AP418i and
transducer, the sensor cables must be executed with an additional, separately grounded, shield in order to ensure protection against
overvoltage. This can be done for example by laying the cable in a metallic pipe or using double-shielded cable, in which case the outer shield
must be connected to ground potential or protective conductor potential where it is close to the connection board (for example where it enters
the switch cabinet). HBM recommends Triaxial cable for this.
