Product Overview

The 8610‑FT‑NA is a non‑arcing snap‑on field‑terminal base for PAC8000 non‑intrinsically‑safe I/O modules such as 8142‑DO‑DC and 8115‑DO‑DCEmerson. It provides screw‑clamp terminals for connecting field instruments, relays and solenoid loads to the corresponding I/O module, and mechanically mates with PAC8000 DIN‑rail carrier. The non‑arcing construction suppresses spark risk during live hot‑swap module replacement, making it suitable for Zone 2 / Div 2 cabinet installations.

This terminal base addresses remote‑I/O deployment challenges: simplified field‑cable termination, safe online hot‑swap operation for non‑IS modules, and drop‑in spare‑part compatibility for PAC8000 remote nodes. Mechanical key‑coding prevents mismatched IS‑module installation onto non‑IS terminal hardware. Automation engineers, oil‑gas pipeline‑site technicians and system‑retrofit integrators benefit most. It mounts on standard PAC8000 DIN‑rail carriers; terminals can be replaced independently without removing the I/O electronics, reducing maintenance downtime for compressor‑station, well‑site and water‑treatment remote‑automation systems.

Key Application Notes

• Passive terminal base; must pair with PAC8000 non‑IS I/O modules; cannot work standalone
• Non‑IS terminal base; must not be used with intrinsically‑safe IS‑series modules; IS modules require blue‑coloured IS terminal bases e.g. 8621‑FT‑ISEaton
• Non‑arcing design permits hot‑swap I/O module exchange while system remains powered online
• Mechanical key‑code prevents mismatched module‑to‑base mating
• Screw‑clamp terminals accept multi‑strand instrument cables; tagging strip included for loop‑point identification
• Approved for Zone 2 / Div 2 cabinet‑mount only; field‑side wiring must comply with local hazardous‑area installation standards
• Conformal‑coated carrier variants available for high‑humidity, high‑contaminant cabinet environments
