Technical Questions

Q: Why 0.063A fuses for analog outputs?

A: This rating protects typical 4-20mA outputs while allowing normal operation and preventing damage from faults.

Q: What are the six terminals used for?

A: They support output wires, sense connections for remote feedback, shields, and test points in precision applications.

Q: How does 60V DC rating help?

A> It provides safety margin beyond typical 24V industrial systems and supports higher voltage applications.

Q: What's the storage temperature range?

A: -40°C to 85°C allows storage in unheated warehouses and during transportation.

Q: When should I choose this fused block?

A: Select it when individual channel protection is needed to prevent one fault from affecting multiple outputs.

Shipping Information

• Shipping Options: FedEx, UPS, DHL Express Services
• Processing Time: Same-day shipping available
• Package Protection: Industrial-grade materials
• Delivery Tracking: Included with all orders

Installation Tip: For precision analog outputs using remote sensing, connect sense wires directly to the load device to compensate for voltage drop in the output wiring. This ensures accurate voltage delivery at the load point.
