FAQ
1. What modules can be installed on the 1701/05 Terminal Base?
It supports a power supply module, dual-channel vibration monitors, Proximitor or transducer I/O modules, and one Keyphasor input module.
2. How many external transducers can be connected?
The terminal base provides I/O terminations for up to nine externally wired transducers.
3. What is the purpose of the Keyphasor input slot?
The Keyphasor input slot allows the connection of a Keyphasor transducer to measure shaft rotational speed and phase reference.
4. Can the terminal base be connected to a network adapter?
Yes, it includes Flexbus connections compatible with Allen-Bradley® 1794 Flex™ I/O or a network adapter for data communication.
5. Does it provide buffered dynamic signal outputs?
Yes, individual buffered outputs are available for each channel, including Keyphasor signals, ensuring signal accessibility for analysis.
6. Is it necessary to use a separate terminal base for each Keyphasor transducer?
Yes, each terminal base can accommodate only one Keyphasor input, so separate bases are required for different shaft speeds.
