+/- 10V Isolated Analog Output Module Product Specifications and Installation Data 1 DESCRIPTION The +/-10V Isolated Analog Output Module (HE693DAC410) 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 (-32,000 to +32,000) residing in %AQ registers to analog voltage signals (- 10 to +10V). The %AQ values are set by the ladder logic program in the PLC CPU. The module may be set to "default to 0V" or "hold last state" when the PLC is taken out of RUN mode. This is accomplished with a configuration parameter in the configuration software.

The two least significant bits of each %AQ are always 0, therefore the smallest decimal step change is 4, which corresponds to 1.25mV. 32,000 8,000 0 0 -32,000 -8,000 -10 0 +10 Output Voltage Figure 3 - Output Voltage vs. %AQ Value and Output Voltage vs. D/A Counts %AQ value D/A counts MAN0052-08 30 NOV 2004 PAGE 3 5 WIRING Figure 4 - Wiring 6 SAFETY AND INSTALLATION All applicable codes and standards need to be followed in the installation of this product. 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. PAGE 4 30 NOV 2004 MAN0052-08 Ensure hands, shoes, and floor are dry before making any connection to a power line. Make sure the unit is turned OFF before making connection to terminals. Make sure all circuits are de- energized before making connections. Before each use, inspect all cables for breaks or cracks in the insulation. Replace immediately if defective. 7 TECHNICAL ASSISTANCE For assistance and technical manual updates, contact Technical Support at the following locations: North America: (317) 916-4274 www.heapg.com email: techsppt@heapg.com Europe: (+) 353-21-4321-266 www.horner-apg.com
