Backplane Bus Communication Velocity and Firmware Flash Compatibility
The IC694TBB032 provides direct terminal pin connectivity to High-Density 16-channel and individually isolated RX3i discrete I/O modules. As a passive interface assembly, it passes discrete and analog signals directly to the host I/O module backplane circuitry without attenuation. This maintains backplane bus communication velocity across the rack backplane while ensuring hardware replacement does not disrupt stored module configurations or firmware flash compatibility routines on the host controller.
Frequently Asked Questions
Q: What wire size and strip length parameters must be followed when landing field conductors on the IC694TBB032? A: Field conductors must be # 14-26 AWG solid or stranded copper wire stripped to a length of 0.310 inches (7.87 mm).
Q: Can the IC694TBB032 terminal block be removed from the host I/O module during system operation? A: The terminal block features a removable design for maintenance, but power must be removed from the module during electronics assembly replacement to prevent hardware damage.
Field Installation Guidelines
- Align the 36-pin screw terminal block assembly with the front connector header of the high-density RX3i I/O module and push firmly until the housing latches seat.
- Strip field conductors to 0.310 inches (7.87 mm) using the stripping reference gauge molded into the bottom of the terminal housing.
- Insert copper wire conductors (# 14-26 AWG) into the terminal cages and tighten screw connections to a maximum torque rating of 7 lb-in.
- Attach the outer terminal cover assembly to shield field wiring connections and secure strain relief routing along cabinet channels.
