- Sixteen configurable current-input channels for selected Tricon analog-input modules
- Precision input conversion, series protection, and redundant 24 V DC field power
- Channel jumpers support isolated transmitter service or approved signal sharing
The Invensys TRICONEX 9771-210 is a user-configurable current-input termination panel for Tricon 3700, 3700A, 3703E, and 3721 analog-input modules.
Each of its sixteen points includes the documented current-to-voltage conversion and series-resistor paths. Redundant 24 V DC inputs can supply field transmitters through diode ORing.
Verify W and W17 jumper positions, module range, panel count, point labels, supply polarity, interface cable, shielding, and any cross-system sharing approval before installation.
Availability, condition, price, and shipping time for Invensys TRICONEX 9771-210 are confirmed during quotation.

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.
- Each current input uses a precision 250 ohm conversion resistor
- Each positive field terminal includes a 180 ohm series resistor
- Match the selected module range to the transmitter and engineering database
- Keep W17 installed when the panel is used with 3700A or 3721
- Remove W17 for documented 3703E extended common-mode operation
- Remove a channel W jumper only for an approved signal-sharing circuit
- Connect redundant 24 V DC sources with correct polarity and protection
- Verify diode-OR source transfer and available voltage under transmitter load
- Use two panels and correct labels for a compatible 32-point module
- Safety-system 4–20 mA transmitter inputs with redundant field power
- Approved transmitter-signal sharing between Tricon and another control system
- Migration of low-density 3700 or 3700A inputs to documented 3721 hardware
