The HE693ADC415 is a high-reliability isolated analog current input module developed by Horner Electric for General Electric (GE) Series 90-30 PLC systems. It establishes a physical isolation barrier between harsh industrial field environments and
It provides an isolation protection capability of 500VAC (RMS)
The module delivers a high data conversion resolution up to 14-bit
Each channel integrates a programmable setpoint at the hardware level
Horner Electric Isolated Analog Current Input Modules provide four analog input channels, with 14-bits of resolution. Two models are available, the HE693ADC420 with 1500VAC (RMS) isolation, and the HE693ADC415 with 500VAC (RMS) isolation. These isolation levels are channel-to-channel and channel-to-ground. The modules convert the current input signals to digital values which are placed directly into the %AI table of the PLC CPU. Each channel may be configured for an input range of 4-20mA or +/-20mA. Each of the four channels has a programmable setpoint, the level of which is set in the PLC program via four %AQ output registers. If the analog input value reaches or exceeds the setpoint, a corresponding digital input %I is energized. The first four %Is represent the four input channel setpoint alarms,respectively.

Water & Wastewater Treatment Industry
Connects to dissolved oxygen (DO) transmitters and ultrasonic level meters in aeration tanks to monitor flow and water quality, preventing ground potential interference caused by large pumps.
Chemical & Petrochemical Industry
Acquires signals from temperature transmitters and pressure sensors inside high-risk reactors, where channel-to-channel isolation prevents a single instrument short circuit from causing a system trip.
Metallurgical & Steel Blast Furnace Industry
Monitors electromagnetic flowmeters and furnace top pressure transmitters in blast furnace cooling systems, with high isolation effectively blocking high-frequency EMI from large electric arc furnaces.
Thermal Power & Boiler Control Industry
Captures three-element feedwater control signals (drum level, steam flow, feedwater flow) in drum boilers to ensure close-loop control precision for high-pressure boiler feedwater systems.
Cement & Building Materials Industry
Gathers signals from multi-point temperature transmitters and exhaust CO analyzers at the rotary kiln head/tail to optimize combustion efficiency and monitor emissions.
Pharmaceutical & Bio-Fermentation Industry
Collects 4-20 mA signals from pH transmitters, load cells, and temperature sensors inside fermentation tanks in real-time to meet strict batch process traceability standards.
Twisted shielded cables must be used throughout connections to field sensors, such as two-wire or four-wire transmitters. The shield layer must be single-ended grounded at a common ground bar on the PLC cabinet side, and dual-ended grounding is prohibited to prevent new ground loops.
Due to the backplane bus characteristics of the Series 90-30 system, hot swapping is strictly prohibited during field maintenance. Backplane and external 24V power must be fully disconnected before removing or inserting the module to prevent permanent damage to the integrated backplane communication circuitry.

Technical notes
Technical notes
The HE693ADC415 delivers a continuous electrical isolation capability up to 500VAC (RMS). Its isolation architecture covers not only channel-to-PLC backplane circuitry (channel-to-ground) but also achieves full physical channel-to-channel isolation. This isolates common-mode voltage noise caused by multi-point grounding and prevents a short-circuit fault on a single sensor from spreading to the rest of the control system.
It is a 4-channel isolated analog current input module designed for the GE Fanuc Series 90-30 PLC system and manufactured by Horner Automation.
What is the primary hardware function of the HE693ADC415 module?
It is used to acquire low-level current signals from industrial field instruments and convert them into digital data that the PLC Central Processing Unit (CPU) can process.
What input signal ranges does HE693ADC415 support?
It supports standard industrial 4 to 20 mA current signals and is also capable of handling bipolar current signals up to +/- 20 mA.
