Deterministic Network Backplane Communication
The IC660BBD120 processes pulse train accumulation independently of host controller PLC scan cycles, executing high-speed counting up to 200 kHz. Built-in digital filtering defaults to a 2.5 us high-frequency threshold for fast encoder signals or a 12.5 ms low-frequency threshold for 40 Hz maximum mechanical contact debouncing. Serial bus data transfers execute deterministically via the Genius RS-485 bus protocol, transmitting accumulated register counts to host Series 90-30 and 90-70 CPUs while maintaining 1500 V galvanic block isolation to preserve signal integrity against common-mode electrical transients.
Frequently Asked Questions
Q: Which base components assemble together to form the complete high-speed counter block assembly?
A: The complete block assembly consists of the electronic module base cataloged as IC660EBD120 mated to the field wiring terminal assembly cataloged as IC660TBD120.
Q: How does switching between high-frequency and low-frequency input filtering change counting performance?
A: Selecting the high-frequency filter sets a 2.5 us minimum input pulse width capable of tracking inputs up to 200 kHz. Selecting the low-frequency filter sets a 12.5 ms minimum pulse width capped at a maximum count rate of 40 Hz to filter out contact chatter.
Field Installation Guidelines
Mount the IC660BBD120 vertically on a panel or DIN rail inside an industrial enclosure, keeping a minimum of 2 inches of free vertical space for thermal heat dissipation. Direct field wiring to the IC660TBD120 terminal assembly, keeping 5-30 VDC encoder and pulse lines segregated from AC power carrying lines. Ground the Genius RS-485 serial communication shield wire at a single point to prevent ground loops across distributed network drops.
