Features:
- Provides four relay outputs: three normally open and one changeover channel.
- Switches up to 2 A resistive at 240 V AC with a 100 mA at 12 V DC minimum load.
- Uses reinforced system insulation and functional channel insulation to 264 V AC.
- Consumes 1.5 W maximum and uses a compact 2.6x8.8x9 cm module body.
Foxboro RLY4 2500M/RLY4/XXXXX/XXXXXX converts four 2500 I/O output commands into isolated mechanical contact paths.
The first three channels use normally open contacts, while the fourth channel supplies the changeover arrangement.
Contact ratings, insulation class, snubber placement, and terminal-unit choice must all match the installed load wiring.
The Foxboro RLY4 2500M/RLY4/XXXXX/XXXXXX Four-Channel Relay Output Module may still be available through Apter Power after OEM discontinuation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
How the four output commands map to contacts
- Channels 1–3: Each uses a normally open relay contact.
- Channel 4: The fourth output uses a changeover contact.
- Status LEDs: Four yellow indicators show individual output states.
- Module state: A green indicator reports module condition.
Electrical boundaries for switched circuits
- AC maximum: The resistive rating is 2 A at 240 V AC.
- DC minimum: The documented minimum is 100 mA at 12 V DC.
- Snubbers: Ax–Bx paths use 22 nF / 100 Ω networks.
- Unsnubbered path: A4–C1 does not include the same internal snubber.
Separation between system, channels, and earth
- System boundary: Reinforced insulation is rated to 264 V AC maximum to earth.
- Channel boundary: Functional insulation is rated to 264 V AC maximum.
- Installation category: The module is marked Category II.
- Power load: Module consumption does not exceed 1.5 W.
Checks at the field-wiring interface
- Terminal type: Verify whether 2500T-T000 or 2500T-T040 is installed.
- Channel 4 wiring: Preserve the changeover contact arrangement.
- Load class: Compare every connected load with the resistive contact limits.
- Order identity: Retain the complete RLY4 2500M/RLY4/XXXXX/XXXXXX label string.
