Backplane Bus Communication & High-Speed Execution
- Determinism & High-Speed Pulse Scanning: The 1745-E155 interface processes high-speed input pulses independently of the standard controller scan time, transferring accumulated count values over the internal backplane bus directly to the master SLC 150 memory registers.
- Firmware Flash Compatibility & Register Addressing: Hardware-addressed counter registers integrate directly into the master SLC 150 processor image table, enabling real-time pulse processing for high-frequency field feedback devices.
- Proximity Isolation & Signal Filtering: Optoisolated input channels and integrated hardware filtering eliminate high-frequency transient noise and cross-talk originating from adjacent field wiring conduits.
Frequently Asked Questions
Q: Can the 1745-E155 high-speed module be connected while the controller backplane is energized?
A: No. Hot-swapping is prohibited. Master AC/DC power to the SLC 150 base unit must be disconnected before installing or removing the 1745-E155 module from the expansion slot or cable header.
Q: What field voltage levels are supported on the 1745-E155 input terminals?
A: The input screw terminals accommodate selectable 5 VDC, 12 VDC, or 24 VDC external signal levels from pulse generators and encoders.
Field Installation Guidelines
- Physical Installation & Panel Mounting: Secure the module inside the chassis or mounting panel using standard retaining hardware. Maintain a minimum vertical clearance of 50 mm (2 inches) above and below the unit for natural thermal dissipation.
- Terminal Wiring Practices: Strip conductor ends to recommended length and secure tightly into the screw terminal blocks. Do not overtighten terminal screws beyond standard industrial torque limits.
- Shielding & Cable Routing: Connect encoder shield wiring to a dedicated single-point earth ground terminal. Route low-voltage DC input cables in dedicated conduits separated from high-voltage AC lines by at least 200 mm to prevent inductive noise coupling.
