IEPE Conditioning Modules

Product catalog summary
Application
IEPE Conditioning Modules are used for signal conditioning in dynamic measurements with piezoelectric IEPE sensors for acceleration, force, and pressure, or IEPE microphones. The M32 model provides signal amplification and anti-aliasing filtering for PC data acquisition systems and is suitable for building multichannel measurement systems. These modules are applicable in industrial, laboratory, and field environments.
Properties
The modules feature a modular system with 4 mm plugs for mechanical and power connections, rugged and compact aluminum cases, and BNC sockets for input and output. They support constant current supply for IEPE sensors and have a sensor status LED indicating three conditions: OK, cable break, and short circuit. The M32 model offers three gain ranges (1, 10, 100) selectable by a rotary switch, high bandwidth, and a replaceable low pass filter module. Power is supplied via a circular DIN connector or banana sockets, with a wide supply voltage range and insulation between signal ground and power supply to avoid grounding issues.
Technical Data
  • Input: IEPE, BNC socket with 3.8 to 5.6 mA constant current, compliance voltage > 24 VDC.
  • Sensor Status Indicator: Three-level LED (input open = off, OK = yellow, short-circuit = red).
  • Gain: M28: 1 ± 0.5%; M32: 1 / 10 / 100 ± 1% typical, ± 2% max.
  • Output Level: > ± 10 VPP depending on sensor.
  • Output Coupling: AC coupled over 10 µF; 220 kΩ parallel for M28, DC coupled; impedance < 100 Ω for M32.
  • Noise at Output: M28: < 1 µVrms (2 to 25 kHz); M32: < 1 mVrms (1 Hz to 50 kHz).
  • Frequency Range (-3 dB): M28: 0.1 Hz to 100 kHz; M32: 0.1 Hz to 30 kHz.
  • Low Pass Filter: M32 uses a plug-in module model FB2...
  • Power Supply: 5 to 26 VDC / 100 mA for M28, 5 to 26 VDC / 200 mA for M32.
  • Operating Temperature Range: -10 to 55 °C, 95% relative humidity, no condensation.
  • Dimensions: M28: 33 x 59 x 44 mm; M32: 56 x 59 x 44 mm.
  • Weight: M28: 120 g; M32: 170 g.
Accessories
Standard accessories include two threaded banana plugs. Optional accessories are available such as filter modules, DIN rail adapters, and mains plug adapters (PS500 and PS1600). The PS500 can power up to 3 M28 units or 1 M32 unit, while the PS1600 can power up to 6 M28 units or 3 M32 units. Low pass plug-in modules for M32 are available in standard frequencies ranging from 0.1 kHz to 30 kHz.
Replacement Models
The M28 and M32 models replace the M27 and M31 models.
