Overview
Essential details：HE693DAC420 Isolated Analog Current Output Module GE
The Analog Current Output Module (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. These channel characteristics are set with configuration parameters in the configuration software or Hand-Held Programmer. A loop power supply (24VDC) must be supplied by the user.

The following Safety Precautions need to be followed.
Wiring needs to be routed in its own conduit.
Shielded, twisted pair extension wiring offers best noise immunity.
If shielded wiring is used, a good earth ground connection, at one end only, is critical. If shields are connected at the module end, terminals 9, 10, 19 and 20 are used as the shield ground point.
Adhere to the following safety precautions whenever any type of connection is made to the module.
Connect the green safety (earth) ground first before making any other connections.
When connecting to electric circuits or pulse-initiating equipment, open their related breakers. Do not make connections to live power lines.
Make connections to the module first; then connect to the circuit to be monitored.
Route power wires in a safe manner in accordance with good practice and local codes.
Wear proper personal protective equipment including safety glasses and insulated gloves when making connections to power circuits.
