Key Features
- Universal analog support—voltage, current, RTD, thermocouple in one module
- High-resolution 24-bit readings with fast multiplexed conversion
- Hot-swappable with RTB terminal block; field wiring remains intact
- Field power and wiring options support two- to four-wire sensor types
Compatible Components & Accessories
- 5094‑MBXT chassis with RTB3/RTB3XT terminal blocks
- Studio 5000 Logix Designer (requires version ≥ 4.02.02 for SSV switch enable)
- 5094‑STB shield bar for field-side grounding
- CompactLogix/Flex5000 controllers via backplane integration
Industry Applications
- Process control in chemical, energy, food/water industries
- Mixed sensor environments requiring flexible input types
- Environments demanding harsh-condition ruggedness
Installation & Maintenance Notes
- Use shielded twisted-pair wiring (like Belden 8761) for optimal signal integrity
- SA field power must be two-wire supply of 18–32 V DC
- Hot-swappable—must switch field power OFF before removal
- XT coating requires maintaining sealed unused slots to preserve protection

Frequently Asked Questions
Can this module read thermocouples directly?
Yes—it supports all major thermocouple types internally, including J, K, T, B, E, N, and more.
How should I wire RTDs?
The module supports 2/3/4-wire RTDs; for best accuracy, use a 4-wire connection with shielded wiring.
Is the XT coating necessary?
XT provides additional protection per ISA S71.04 G3—important in corrosive or harsh industrial environments.
