Information
- Emerson 8626-FT-IS. This field terminal joins RTD sensor wiring to an intrinsically safe PAC8000 temperature-input channel; measurement conversion belongs to the paired 8206-TI-IS module.
Matched I/O module: 8206-TI-IS, eight-channel RTD input
RTD wiring: Two-, three- or four-wire diagrams
Field-terminal key: C / 3 with 8206-TI-IS
The intrinsically safe assembly uses mechanical key position C/3 for the 8206-TI-IS pairing. The terminal has module-side multipin connectors, screw-clamp field connections and an identification strip. Its blue moulding identifies IS field wiring; a field terminal alone does not establish the whole loop certificate or replace the module, carrier and power arrangement.
IECEx BAS 12.0023U limits terminal input/output voltage to 30 V and 8626-FT-IS input power to 0.9 W. The certificate also calls for consideration of segregation at 30 V when assessing combined assembly output parameters. Carry the applicable control drawing, sensor entity parameters and area classification through the installation review.

Prepared by Apter Power - PDF, 5 pages. Identity, installed-system checks, commissioning and handover.
Compatibility boundary: Use the RTD terminal wiring diagram and the approved intrinsic-safety assembly for the selected two-, three- or four-wire sensor.
-
Two-wire RTD
Use the terminal sheet’s two-wire connection diagram when the installed sensor and input configuration require a two-lead RTD. -
Three-wire RTD
Route the compensation conductor according to the dedicated three-wire diagram and verify the corresponding channel configuration. -
Four-wire RTD
Terminate separate excitation and sense conductors using the four-wire diagram for the selected RTD channel. -
Module replacement
Retain the 8206-TI-IS pairing and C/3 key relationship when exchanging a field terminal in a PAC8000 IS assembly.
Follow the site hazardous-area and isolation procedure before disturbing field connections.
Confirm 8206-TI-IS and the C/3 mechanical key before fitting 8626-FT-IS.
Identify every two-, three- or four-wire conductor against the correct terminal diagram.
Assess the 30 V and 0.9 W certificate limits in the complete approved loop.
Check screw-clamp security, conductor identification and separation of IS wiring.
After restoration, compare each temperature channel with a known process or test reference.
