Part: HE693ADC405
Category: PLC/ Machine Control
Subfield: PLC modules/racks
The HE693ADC405 has four analog input channels, including 14-bit resolution. Two models are available, the HE693ADC410 with 1500VAC (RMS) isolation and the HE693ADC405 with 500VAC (RMS) isolation. Isolation levels are inter-channel and channel-to-ground. These modules convert the voltage signal into a digital value (-32,000 tp +32,000), which can be found directly in the %AI table of the PLC CPU. Each individual channel (there are four channels) includes a programmable set point. Its level is set in the PLC program by four %AQ output registers. When the analog input value reaches or exceeds the set value, the corresponding digital input %I is energized. The first four %Is represent each of the four input channel set point alarms. As needed
