The HE693DAC420 provides four analog output channels, with 14-bits of resolution, and 1500VAC (RMS) isolation channel-to-channel and channel-to-ground. The module converts digital values (0 to +32,000) residing in %AQ registers to analog current signals. The %AQ values are set by the ladder logic program in the PLC CPU. Each channel may be set to "default to 4/0mA" or "hold last state" when the PLC is taken out of RUN mode. The output mode of each channel may be set to 4-20mA or 0-20mA.

  • Question: What is a HE693DAC420? Answer: The HE693DAC420 provides four analog output channels, with 14-bits of resolution, and 1500VAC (RMS) isolation channel-to-channel and channel-to-ground. The module converts digital values (0 to +32,000) residing in %AQ registers to analog current signals.
  • Question: What is the main power supply for the HE693DAC420? Answer: The main power source for the HE693DAC420 uses 90mA @ 5VDC   or 120mA @ 24VDC.
  • Question: How can I minimize capacitive loading and noise? Answer: Shielded, twisted-pair extension wiring offers the best noise immunity. 
  • Question: Where should the shields be connected to? Answer: If shielded wiring is used, a good earth ground connection is critical. If shields are connected at the module end, terminals 9, 10, 19 and 20 are used as the shield ground point.
  • Question: Can I change the number of channels or the voltage on this device? Answer: Yes, you can. This is a 4 channel unit.

PDFsupply Tech

The HE693DAC420 is similar to the HE693DAC410 by providing four analog output channels, 14 bits of resolution and 1500VAC isolation. The user must supply a loop power supply for this module.
