FAQ
Reader questions
Can DS909 2M31107 S31107 be used in high vibration environments?
Yes, the device features reinforced terminal screws and conformal coating to withstand vibration when installed according to mechanical guidelines.
What is the recommended wiring gauge for the input terminals?
Use 18 to 22 AWG stranded wire with properly crimped spade connectors to ensure secure contact and reduce wire fatigue.
How does the module handle common mode voltage on analog inputs?
Internal filtering and isolation barriers suppress common mode interference, allowing reliable readings from sensors in noisy locations.
Is replacement field serviceable, or must the entire unit be replaced?
Most field service engineers replace the entire module, as internal calibration and fuse configuration are not user adjustable.
