PRODUCT DATA SHEETPCH Raw Box CHB 1145 CHB 1145 The PCH Raw Box, type CHB 1145 is a stand alone module offering buffered outputs from existing vibration monitoring setups using either IEPE, AC or Proximity Probe inputs. The five input channels accept positive or negative signals and can include a BIAS voltage. 4 outputs are available from the BNC outputs and in total 5 outputs are available from the screw terminals. All outputs are biased as the source and without unity gain. Signal Input 4 GND GND Signal Input 3 +24V (Power) GND (Power) GND Buff. Out 5 Specifications:5 inputs, operating voltage: Inputs signals can be applied as positive or negative biased signals. IEPE Inputs Proximity Driver Input AC+DC Input Active signals from existing vibration monitors with integrated power supply IEPE can be connected to the Sig In screw terminals in parallel. The existing BIAS and AC signals are available in 1 -to-1 relation on the BNC connectors as well as from screw terminals. Signal response: We recommend max 1-2 meters of coax cable between portable equipment to BNCs and twisted-paired signal cable between PCH Raw Box to the receiving signal conditioner. Note: connecting to both screw terminals and BNCs will increase the total impedance! Max cable load capacitance 0.1 nF: Max cable load capacitance 1.0 nF: equipment from Signal In 1-4. We recommend that 5 outputs are available from screw terminals. Channel 1-4 is shared with the BNC outputs marked 1-4. Pay attention to the total load impedance/capacitance from any connected receivers if both screw terminals and BNCs are used simultaneously.
