Product Description

The Emerson GE ST-1218 (manufactured by Crevis for the RSTi series) is a high-density distributed I/O slice module designed for modern industrial control architectures. This module provides 8 discrete input channels, facilitating the integration of field sensor signals into a centralized control system via the RSTi fieldbus network. Engineered for versatility, the ST-1218 supports both 12V and 24V DC logic levels, making it compatible with a wide array of proximity switches, limit switches, and photoelectric sensors.

As part of the RSTi distributed I/O family, the ST-1218 emphasizes a compact form factor to minimize cabinet space while maintaining high-speed data throughput. Its modular "slice" design allows engineers to scale I/O capacity incrementally, ensuring the system remains cost-effective and flexible. The module features advanced galvanic isolation to protect the internal bus electronics from field-side electrical noise and surges, ensuring high signal integrity in high-EMI environments.
