Module Pin-outs (all 8 inputs are the same)
MDAQ-SUB-ACC-A-BNC version
Typical Sensor Hook-ups
Above left: IEPE sensor mode Above right: Voltage input mode
For constant current powered sensors (IEPE) the current source is switched on and the minus input of the
BNC is connected to GND. In this mode the TEDS interface circuit is activated so that it can read the sensor
information from IEEE 1451.4 compliant sensors (the TEDS interface is disabled in the voltage mode).
In all voltage measurement modes the current source is disconnected from the input signal.
The position of the GND switch denes if the amplier is used for differential or singled-ended input congu-
ration. The allowed input voltage range (common mode voltage) is limited to 12 V.
⇒ The constant current supply (4 or 8 mA) that you set on one channel, will apply to all 8 channels of this MDAQ-
SUB module. However, other MDAQ-SUB modules may be set to dierent constant current levels.
