Brand New Original ABB Modules SPNIS21, SPNPM22

ABB SPNIS21 is an S100 I/O bus interface module designed specifically for the Advant Controller 410 system. It is used to connect the controller with S100 series I/O substations, enabling high-speed and reliable real-time data exchange. It is suitable for industrial automation control core architecture.

Core functions and features

High speed communication:

Supports S100 parallel bus protocol, with a transmission rate of 1.5 Mbps, ensuring low latency control.

Scalability:

A single module supports connecting up to 8 S100 I/O sub stations, greatly expanding the number of I/O points.

Compact integration:

Directly plugged into the AC 410 controller rack, without the need for additional power supply, saving space.

Diagnostic indication:

Equipped with dual color LED status lights (running/faulty), real-time monitoring of bus communication status.

Redundancy compatibility:

Can be configured as a redundant mode to enhance system reliability (requires the use of redundant controllers).

Typical application scenarios

Core expansion of DCS control systems in the power and petrochemical industries.

Connect S100 remote I/O station (such as analog/digital acquisition module).

Traditional Advant OCS system upgrade and renovation project.

Note: This module has been discontinued and replaced with modern bus interfaces such as CI854 (supporting Profibus/Modbus). It is recommended to use the new model for new projects.
