XBE-TN16A

Description

16-point sinking transistor DC output module, 12/24 VDC rated, doubling channel density while keeping the same protection and electrical characteristics as TN08A. Good mid-density DC switching module.

The Polar Energy Assessment:

The TN16A provides 16 sinking transistor outputs in the XGB expansion form factor, with typical specs of 0.2–0.5 A per point depending on exact SKU documentation, 2 A per common, low on voltage drop, and photocoupler insulation. It supports the same operational voltage window (~10.2–26.4 VDC), quick switching times, and zener-based transient protection, making it suitable for systems where more channel count matters without moving to relay outputs. Verify the specific per-point current variant for your SKU when planning driver loads.

Pros

• Higher channel density, same fast switching and longer life than relays.
• Standardized form factor and wiring with other XBE modules.

Limitations

• Still sink-type only; choose NPN vs PNP logic to match field devices.
• Per-point current limits mean heavier DC loads require external drivers.

Typical use cases

• Indicator banks, low-current DC actuators, and expanding digital outputs where TTL-style switching is fine.
