ST-3214 GE Fanuc RSTi Digital Output Module

Product Overview

The ST-3214 (ST-3214) is a compact 4-channel digital output module designed for the GE Fanuc (Emerson) RSTi distributed I/O system. This module provides four independent 24 VDC sourcing outputs, allowing a controller to drive field devices such as solenoid valves, small DC motors, and pilot lights. As part of the RSTi "slice" I/O family, the ST-3214 facilitates granular system expansion, enabling engineers to add exactly the number of output points required for a specific machine or process. Its narrow form factor is ideal for high-density control cabinets where rail space is at a premium. We supply this module as 100% Brand New, ensuring factory-sealed performance for your automated logic systems.

Technical Specifications

The ST-3214 utilizes high-side switching technology to provide robust control signals to industrial loads.

Engineering Advantages

• Space-Efficient Slice Design: At only 12 mm wide, the ST-3214 allows for precise scaling of output counts without wasting cabinet space. This modularity is essential for decentralized I/O stations located directly on machinery.

• Integrated Protection Circuitry: The module features internal over-current and thermal shutdown protection. In the event of a field-side short circuit, the module protects the internal bus and adjacent modules, localized the fault to a single channel.

• Simplified Maintenance: The push-in spring-clamp terminal system ensures secure, gas-tight connections that resist loosening in high-vibration environments. The removable terminal block allows for module replacement without rewiring, minimizing downtime.

• Real-Time Diagnostics: Dedicated LEDs for each channel provide instant verification of output status. This visual feedback assists technicians in differentiating between a logic-side command failure and a field-side wiring or device issue.

FAQs

• What is the difference between the ST-3214 and ST-3218?

  The ST-3214 provides 4 output channels, whereas the ST-3218 provides 8 output channels. Choose the ST-3214 when you need smaller increments of I/O or have specific current-density requirements.

• Does this module require a separate field power supply?

  The 24 VDC used for the outputs is supplied through the internal power bus of the RSTi assembly. You must ensure your Network Adapter or Power Expansion module is correctly fed with 24 VDC.

• Can I drive an AC load with this module?

  No. The ST-3214 is strictly for 24 VDC sourcing applications. To drive AC loads, you must use an interposing relay or a specific AC output module from the RSTi series.

• Is it compatible with any RSTi Network Adapter?

  Yes. The ST-3214 is a standard slice that communicates via the RSTi internal bus, making it compatible with PROFIBUS, PROFINET, DeviceNet, and Modbus TCP adapters.
