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.
