More Details
Description: The SNAP-AIVRMS module provides an input range of 0 to 250 volts AC or DC. The SNAP-AIVRMS module may be used to monitor 120/240-volt AC/DC and 12/24/48-volt AC/DC system voltage. Terminals 3, 4, 7, and 8 share a common connection inside the module. Make sure you observe polarity when connecting the second channel. To avoid a potentially hazardous short, double-check wiring before turning on the voltage to be monitored. If you need a module with channel-to-channel isolation, see form #1182, the SNAP Isolated Analog Input Modules Data Sheet. |  |
What is the input voltage range of the SNAP-AIVRMS module? The module supports an input range of 0 to 250 volts AC or DC. Can I use this module to monitor both AC and DC voltages? Yes, the SNAP-AIVRMS can monitor both AC and DC voltages, including standard voltages such as 120V and 240V AC/DC and 12V, 24V, and 48V AC/DC. Are the input channels isolated from each other? The standard module has common connections between certain terminals. If channel-to-channel isolation is required, consider using an isolated analog input module. How should I connect the wires to avoid short circuits? Ensure proper polarity when connecting wires, particularly for the second channel. Always double-check the wiring before applying voltage. |
