High-Speed Counter Modules for Compact FieldPoint
Field I/O Connections
Compact FieldPoint modules include a built-in power distribution bus that provides multiple power connections on the module. A field-wired power
supply connected to the voltage (V) and common (C) terminals is internally connected to a power distribution bus that offers additional breakout
terminals for voltage supply (V
SUP
) and common (COM). These terminals deliver a convenient way to distribute power to field devices that require
external power.
The cFP-CTR-500 and cFP-CTR-502 have:
• 8 high-speed digital counter input terminals (V
IN
)
• 4 digital gate input terminals (V
IN
)
• 4 digital output terminals (V
OUT
)
• 8 common terminals (COM)
• 8 power connections to power field devices (V
SUP
)
