The Horner Millivolt Input Modules (HE693ADC406 / 409) permit DC millivolt-level signals to be connected to the PLC directly without processing external signals (transducers, transmitters, etc.). The module processes analog and digital signals and millivolt values are written to the PLC %AI input table with 14-bit resolution. The module has 4 channels and an input range that is selectable from +/-25mVdc, +/-50mVdc, and +/-100mVdc. The configuration software or a Hand-Held Programmer (HHP) allow an input range to be selected. Selectable digital filtering can aid by providing a steady input signal in a loud environment. Field wiring is made to a removable 20-pin terminal strip.

  • Question: What is a HE693ADC409? Answer: The HE693ADC409 allows DC millivolt-level signals to be connected to a PLC directly without processing external signals such as transducers, transmitters, etc. 
  • Question: What is the main power supply for the HE693ADC409? Answer: The main power source for this unit comes from 100mA @ 5VDC which is supplied by the PLC power supply.
  • Question: How can I minimize capacitive loading and noise? Answer: Shielded, twisted-pair extension wiring offers the best noise immunity. 
  • Question: Where should the shields be connected to? Answer: Shields may be connected at the module's end. Terminals 19 and 20 may be used as the shield ground point.
  • Question: Can I change the number of channels or the voltage on this device? Answer: Yes, you can. This is a 4 channel unit.
  • Question: What is a good way to test the HE693ADC409? Answer: The best method to test this unit is to use a millivolt generator to probe each channel for consistency and stability. 
  • Question: How to tell if your HE693ADC409 is faulty. Answer: Reference the response to each channel. Check for consistency and stability in the I/O tables.
