MODICON AM-S980-100 Redundancy Interface Module

MODICON AM-S980-100 is a high-performance redundancy module for Modicon 984 series PLC automation systems. This redundancy module is designed for hot standby CPU synchronization between master and standby racks. The redundancy module adopts high-speed parallel link and noise suppression circuit layout. This redundancy module supports stable uninterrupted operation in power, chemical, oil & gas and critical process control production lines.

It serves as a core redundancy synchronizer to mirror register data, I/O status and program runtime information between two processor units. The redundancy synchronizer continuously compares data consistency and triggers bumpless transfer upon main CPU failure. This redundancy synchronizer provides LED indicators for link status, power and fault diagnosis. The redundancy synchronizer is fully compatible with AS-S980 series redundancy accessories and Modicon 984 CPU racks.

The unit delivers dependable hot standby switching for high-availability control loops that require zero downtime. Accurate hot standby switching ensures seamless takeover without process interruption. Stable hot standby switching avoids unplanned shutdown and improves overall system uptime. The hot standby switching of this model meets strict industrial high-reliability automation standards.
