الوصف
The GE DS200RTBAG2A is a Relay Output Card rated for 24VDC. It serves as a crucial interface, translating the low-voltage digital signals from a control system into isolated, high-power outputs capable of switching external field devices. The G2A in the part number signifies a specific hardware revision.
Technical Breakdown 🧠
The card’s function is foundational to bridging the gap between control logic and real-world machinery:
- Relay Outputs: The card is equipped with multiple relays, which are electromechanical switches. The control system sends a low-power signal to the relay’s coil, which in turn closes a physical contact. This physical contact can then switch a separate, higher-voltage/current circuit. This is a primary method for a control system to turn on or off a field device.
- Galvanic Isolation: The use of relays provides galvanic isolation, which is a critical safety and protection feature. The control circuit is completely separated from the output circuit, protecting the sensitive electronics of the control system from voltage spikes, electrical noise, and high currents from the field.
- 24VDC Rating: The 24VDC rating specifies the voltage of the output circuits the card can reliably switch. This is a common, low-voltage standard in many industrial and automation applications, valued for its safety and reliability in driving devices like solenoids, contactors, and other auxiliary equipment.
