PRODUCT DESCRIPTION
Isolated analog current input module
HE693ADC415 is a Horner Electric isolated analog current input module with four channels. Each channel accepts a configured 4 to 20 mA or bipolar 20 mA signal and places its converted value in the PLC analog input table, with usable resolution of thirteen bits plus sign.
The module provides programmable per-channel setpoint indications and configurable digital filtering. Use the ADC415-specific wiring diagram and its 500 VAC RMS isolation rating; the related ADC420 has different isolation and terminal assignments. Match the PLC register allocation, channel range and scaling to the application before commissioning.

ACTUAL APPLICATIONS
Current-signal acquisition and setpoint monitoring
The following contexts use the measurement, scaling and alarm functions documented in Horner MAN0042-06. They do not claim installation of this exact module in a named plant or project.
-
01 · PROCESS MEASUREMENT
Read four analog current signals
The module converts configured current inputs into values in the PLC %AI table. For a 4 to 20 mA measurement channel, the control program applies the documented scaling relationship to obtain the signal current before converting it into process engineering units. -
02 · BIPOLAR SIGNALS
Acquire signed current measurements
A channel configured for the bipolar 20 mA range returns signed measurement values. Match the channel configuration and PLC scaling so negative readings are interpreted correctly instead of treating the channel as a unipolar transmitter input. -
03 · THRESHOLD MONITORING
Compare measurements with programmed setpoints
The PLC supplies four setpoints through %AQ registers. When a channel measurement reaches or exceeds its setpoint, the corresponding %I indication is energized; the application can use that indication as a measured-value threshold status, not as a claimed safety-rated trip function.

Manuals & support
ISOLATED ANALOG CURRENT INPUT MODULE
Configure current inputs and PLC register allocation
Horner MAN0042-06 documents four %AI registers, four %AQ registers and sixteen %I bits for the module. LM90 configuration uses the Foreign Module selection, with the documented configuration bytes controlling current range and digital filtering.
The ADC415 rating is 500 VAC RMS channel-to-channel and channel-to-ground, distinct from the ADC420 rating. Use only the ADC415 terminal diagram and verify signal polarity, range and the applicable installation instructions before connecting field wiring.
For noise control, the manual recommends shielded twisted-pair wiring routed in its own conduit, with the shield grounded at one end only. Digital filtering can trade response speed for smoothing; select its setting to suit the required measurement response.
Features:
- Allocate 4 %AI, 4 %AQ and 16 %I
- Keep ADC415 and ADC420 wiring assignments distinct
- Match digital filtering to the required response time
The HE693ADC415 analog input module requires appropriate configuration before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
For an HE693ADC415 replacement, compare the complete module identity and preserve the configured channel ranges, PLC register allocation, scaling and filter setting. A physically similar analog module may require a different wiring and configuration arrangement.
MAN0042-06 covers both ADC415 and ADC420, but specifies different isolation levels and terminal assignments. That shared document does not establish the ADC420 as an unconditional drop-in replacement for the ADC415.
No exact current lifecycle notice, verified withdrawal date or designated successor was obtained for this module. The date on MAN0042-06 identifies a historical document issue, not a manufacturer-announced discontinuation date.
Features:
- Preserve channel configuration and PLC mapping
- Verify isolation and terminal assignment before substitution
- Do not treat a manual date as a lifecycle notice
The HE693ADC415 analog input module requires replacement verification against the complete installed configuration and current manufacturer documentation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about HE693ADC415
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Can HE693ADC415 channels use different current ranges?
Each channel may be configured for 4 to 20 mA or +/-20 mA. Set the documented channel configuration bytes and use the matching scaling formula in the PLC program. -
How many PLC registers does the module require?
MAN0042-06 specifies four %AI registers, four %AQ registers and sixteen %I bits. The %AQ registers provide the channel setpoints, while the first four %I indications correspond to the channel setpoint alarms. -
What is the difference between ADC415 and ADC420 isolation?
The ADC415 specification is 500 VAC RMS channel-to-channel and channel-to-ground; ADC420 is rated 1500 VAC RMS. Their wiring diagrams also differ, so neither the higher rating nor the terminal assignment should be transferred to ADC415. -
Why does the raw input value change in steps of four?
The manual states that the two least significant bits of each %AI value are always zero. The smallest decimal step is therefore four, corresponding to 2 microamps in the 4 to 20 mA range or 2.5 microamps in the bipolar range. -
How is a channel setpoint alarm generated?
The PLC writes the setpoint through the corresponding %AQ register. If the measured input reaches or exceeds that setpoint, the matching %I indication is energized. The manual does not establish this as a safety-rated protective function. -
How does digital filtering affect response?
Digital filtering uses 1 to 128 samples per update. Greater filtering changes how quickly a current step appears in the reported value; use the response curves in MAN0042-06 when selecting the configuration. -
Should the cable shield be grounded at both ends?
The installation guidance calls for a good earth connection at one end only. Use shielded twisted-pair wiring and follow the ADC415-specific shield terminal assignments in the manual.
