Features:
- Provides 4 isolated inputs with 14-bit resolution and 500VAC isolation.
- Each channel has programmable setpoints with %I alarm outputs.
- Supports 4-20mA and ±20mA ranges via software configuration.
The HE693ADC415 provides four isolated analog current input channels with 14-bit resolution, enabling accurate conversion of 4-20mA or ±20mA signals from field devices such as transmitters and sensors. With 500VAC (RMS) isolation between channels and ground, the HE693ADC415 ensures reliable operation in electrically noisy industrial environments. Each channel converts current signals to digital values placed directly into the %AI table of the PLC CPU. The HE693ADC415 has an input impedance of 100 ohms and uses an integrating 18-bit A/D converter with 13 bits plus sign usable resolution.
The HE693ADC415 features programmable setpoints for each of its four channels, with levels set via four %AQ output registers in the PLC program. When the HE693ADC415's analog input value reaches or exceeds the setpoint, a corresponding digital input %I is energized for alarm indication. The HE693ADC415 includes analog filtering of 1KHz (3-pole Bessel) and digital filtering of 1-128 samples per update for noise rejection. The HE693ADC415 offers common mode rejection >100dB and maximum error of 0.05% full scale.
The HE693ADC415 is configured using the LM90 Configuration Package with parameters including %I Size, %AI Size, %AQ Size, Byte 1, Byte 2, and Bytes 3-6. The HE693ADC415 supports scaling formulas for 4-20mA (mA = %AI / 32,000 x 16 + 4) and ±20mA (mA = %AI / 32,000 x 20). The HE693ADC415 operates from 0 to 60°C with 5-95% non-condensing humidity and requires shielded twisted-pair wiring with earth ground connection at one end only for optimal noise immunity.
The HE693ADC415 GE Analog Current Input Module may still be available for purchase and support from Apter Power beyond
End-Of-Life (EOL) by the manufacturer (OEM).

- Four current channels are converted at an aggregate update rate of 45 channels per second.
- The integrating converter provides 13 bits plus sign of usable resolution with 0.05% full-scale maximum error.
- A 1 kHz three-pole Bessel analog filter is complemented by selectable digital averaging from 1 to 128 samples.
- Each channel is isolated from the other channels and ground at 500 VAC RMS or +/-700 VDC.
- Common-mode rejection exceeds 100 dB, supporting measurements in electrically noisy industrial installations.
- Shielded twisted-pair conductors should be routed separately and grounded at one end to limit coupled noise.
- LM90 identifies the unit as a Foreign module after selecting the occupied slot in I/O Configuration.
- The PLC allocation requires 4 %AI words, 4 %AQ words and 16 %I points for values, setpoints and status.
- Configuration bytes select 4-20 mA or bipolar +/-20 mA operation and set the desired digital filtering response.
