• SCC standard connector for carrier interface
• Conformal coated PCB assembly
• Compact modular design

Working Principle The module receives digital data from the host DAQ device’s digital-to-analog converter (DAC), conditions and amplifies the analog signal, and provides an isolated voltage output. The internal isolation barrier separates the DAQ system ground from the field side, eliminating ground loops and protecting system equipment from common-mode voltage transients.

Installation Requirements

• Install in compatible NI SCC carrier chassis
• Use 16 AWG to 26 AWG copper conductors for output wiring
• Observe proper polarity for output connections
• Ensure total load impedance does not exceed specified limits
• Do not connect to signals exceeding Measurement Category I limits
• Operate in indoor, pollution degree 2 environments only

Usage Notes

• Do not apply external voltage to output terminals when module is unpowered
• Verify output range and polarity before connecting to load
• Two modules may be connected in series only for ungrounded loads
• Do not use for medical or life-support applications
• Avoid operation near strong electromagnetic interference sources
• Static discharge can damage components; use ESD precautions
