More Information

Overview Manuals Channel Setup Data Scaling Thermistors Input Wiring

Features:

  • Consolidates twelve mixed analog points in one SmartStack position.
  • Lets each channel use a thermistor, current or voltage input.
  • Supplies 12-bit field data to the controller register map.
Horner HE800ADC920 identifies the metal-case ADC920 ordering configuration; HE-ADC920 is the plastic-case version covered by the same product documentation.

The mixed-input design suits control panels that collect temperature sensors and analog transmitters without assigning a separate module type to each signal family.

Before matching a replacement, confirm twelve required input points, SmartStack host compatibility, the C1/C2/C3 field returns and the programming-plug position for every channel.

The Horner HE800ADC920 Multi-Type Analog Input Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

HE800ADC920 Channel Setup

  • Independent choice: Each of the twelve channels can be assigned its own thermistor, current or voltage input type.
  • Software entry: Cscape stores the selected input type and temperature format for each channel.
  • Hardware match: The programming plug behind each input must be positioned for 5 V, thermistor or 20 mA operation.
  • Point mapping: Controller I/O registers are determined by the model and its location in the SmartStack.

HE800ADC920 Data Scaling

  • Voltage factor: The 0–5 VDC range uses a conversion factor of 0.00015625 V per count.
  • Current factor: The 0–20 mA range uses a conversion factor of 0.000625 mA per count.
  • Temperature data: Celsius and Fahrenheit values are returned in tenths of a degree.
  • Controller update: Converted values are transferred in relation to the PLC scan.

HE800ADC920 Thermistor Inputs

  • Supported curve: The module supports Kele Engineering Precon Type III 10 kΩ thermistors.
  • YSI support: Listed 10 kΩ Yellow Springs Instruments devices use a Beta value of 3574.
  • Temperature span: The documented thermistor range is -37 to 115°C or -35 to 240°F.
  • Common terminal: Thermistor circuits use the C1 common connection.

HE800ADC920 Input Wiring

  • Current loops: The wiring supports both externally powered and self-powered 20 mA sources.
  • Signal commons: C1 serves thermistors, C2 serves 0–5 VDC and C3 serves 20 mA channels.
  • Cable practice: Shielded twisted-pair cable is recommended for best analog performance.
  • Safe servicing: Controller, CAN-port and peripheral power must be removed before adding or replacing the module.
Description
Horner HE800ADC920 combines twelve 12-bit analog channels in a metal-case SmartStack module. Each channel can be assigned to thermistor, 0–20 mA or 0–5 VDC service, allowing mixed field signals to share one module without forcing every point into the same range.

The HE800ADC920 pairs independent software range selection with a channel jumper position for the chosen signal type. Digital filtering can be adjusted in Cscape, and thermistor channels can be represented in Celsius or Fahrenheit while the I/O map follows the module model and stack location.

The HE800ADC920 provides separate common connections for thermistor, voltage and current wiring. Accurate results depend on matching the channel setting to the jumper, using the correct common and keeping shielded twisted-pair signal wiring separated from interference sources.

Technical notes
Horner HE800ADC920 provides twelve 12-bit SmartStack inputs with independently selectable thermistor, 0–20 mA or 0–5 VDC operation. Software configuration and the physical channel jumper must agree.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How many sensor families can share one Horner HE800ADC920 module?
Horner HE800ADC920 accepts thermistors, 0–5 VDC transmitters and 0–20 mA transmitters across twelve independently assigned channels.
Why can a Horner HE800ADC920 channel disagree with its Cscape selection?
The physical programming plug on Horner HE800ADC920 may be in a different position. Align that plug with the software choice for the affected point.
Can the digital filter in Horner HE800ADC920 calm a fluctuating temperature measurement?
Yes. Increase the Horner HE800ADC920 filter constant gradually, then check sensor cabling and grounding so filtering does not hide a wiring fault.
How is a raw thermistor word from Horner HE800ADC920 interpreted?
Horner HE800ADC920 reports temperature in tenths of the selected unit; a word of 250 therefore means 25.0 degrees Celsius or Fahrenheit.
Which setup fault sends a Horner HE800ADC920 20 mA point toward overrange?
A mismatched jumper or software choice can misread the point. Horner HE800ADC920 also requires the 20 mA circuit to return through C3 and remain below 35 mA continuously.
Why are C1, C2 and C3 not interchangeable on Horner HE800ADC920?
They serve different measurement circuits on Horner HE800ADC920: C1 is for thermistors, C2 for 5 V inputs and C3 for 20 mA inputs.
