Solution:

To work our DAS cards with PPC-120/150, the power consumption and the space are the main regards. Since some old PPC-120/150, it dose not provide -5V on the bus, we have to check the power consumption of the cards first. Fortunately all PCL-818 family, PCI-1710/1710HG and PCI-1713 can work without -5V power supply. Secondly, we have tried to install those cards on PPC-120/150. The space inside the housing are enough for them, only the 'gateway' is too small, we need to dismantle the cover and install them. After checking these point, we think it is no problem working PPC-120/150 with these cards. And we also installed PCI-1710HG on PPC-120 for test, and it works well. The user have mentioned that he want to read thermocouple and 4-20mA signal. It is recommended to use PCI-1710HG + PCLD-8710 or PCL-818HG + PCLD-8115 to read TC, and for 4-20mA signal user can cascade a 250 ohm resistor to transfer it to voltage signal.
