Overview of the NP1BS-11S Base Board

The NP1BS-11S serves as the physical backbone for MICREX-SX SPH programmable controllers. This base board carries the power supply, CPU, and I/O modules within one rack assembly. Engineers rely on it when building medium to large control systems with moderate module counts.

Slot Configuration and Bus Architecture

Eleven slots accommodate one power supply unit, one CPU module, and nine I/O or special modules. Furthermore, three slots feature processor bus connectors for high-speed data exchange. The remaining slots operate on the standard SX bus for general I/O communication.

Physical Dimensions and Mounting

The unit measures 482 mm wide, 210 mm deep, and 88 mm high. Meanwhile, the NP1BS-11S weighs approximately 730 g. Installation uses standard DIN rail mounting or screw fixation for panel or rack setups.

Electrical Characteristics and Power

Internal power consumption reaches 70 mA or less at 24 V DC. The base board remains passive and contains no energy storage components. Instead, it relies entirely on the mounted power supply module for voltage distribution.

Integration Features

The built-in station number switch supports SX-Net networking applications. Consequently, the NP1BS-11S enables multi-station configurations without additional hardware. The standard base board suits常规 projects that prioritize cost efficiency over extreme bus speeds.
