HE693ADC405

The HE693ADC405 analog input module, part of Horner Electric's PLC I/O lineup, is engineered for precise measurement and control applications. It accommodates an input range of +/- 10 Volts across four channels, ideal for capturing a variety of signals in industrial settings.

For effective performance, this module demands a combination of 4 %AI, 4 %AQ, and 16%I in terms of input and output. The steady-state power consumption measures at 0.4 watts (80mA) when powered at 5 volts and 2.16 watts (90mA) at 24 volts, ensuring energy efficiency. Upon power-up, the surge current reaches 120mA at 5 volts and 150mA at 24 volts, allowing for a controlled initialization.

This analog input module provides a resolution capability of 13 bits plus sign, allowing for detailed signal representation. Operating with a module update rate of 45 channels per second, it efficiently processes incoming data.

Designed with advanced filtering technology, the 1 kHz, 3-pole Bessel filter contributes to eliminating noise and enhances signal integrity. It features an input impedance of 1 Megohm, which is critical for most source types.

The HE693ADC405 further ensures reliability and safety through channel-to-channel isolation rated at 500 VAC (RMS) and +/- 700 VDC, along with a common mode range characterized by similar voltage ratings. Common mode rejection remains impressive at greater than 100 dB, affirming its capability to mitigate noise.

Lastly, the module supports a maximum overvoltage threshold of +/- 15 VDC while maintaining an impressive maximum error rate of 0.05% full scale, thereby guaranteeing precision in operational environments.
