+86 1535940827516-Point Isolated Analog Input Module - Tricon Safety System
Triconex 3703E is a 16-point isolated analog input module for the Tricon TMR safety platform. It accepts configured 0 to 5 VDC or 0 to 10 VDC signals and provides channel isolation for field measurements used by safety and critical-control logic.
Triple modular redundant input processing supports diagnostic comparison of the acquired signals. The correct voltage range and engineering scaling are defined in the application configuration and must match the connected transmitters and termination hardware.
Before replacement, verify the complete 3703E revision, chassis slot, input range, field termination, channel allocation and project database. Perform channel-by-channel loop checks and the approved safety functional test after installation.

Triconex 3703E provides 16 individually isolated analog input channels for a compatible Tricon TMR safety-system configuration.
Triconex 3703E supports configured 0 to 5 VDC or 0 to 10 VDC input ranges, which must match the project database and field transmitters.
Individual isolation helps separate field circuits and supports reliable measurement when channel references or fault conditions differ across the installation.
No. Triconex 3703E is a 16-point isolated input module, while 3704E has a different high-density commoned input architecture and termination requirement.
Verify the module revision, chassis slot, termination assembly, configured range, scaling, channel allocation and field wiring polarity.
Inject approved test values into each channel, confirm engineering scaling and diagnostics, and complete the required safety-loop validation.
Provide the complete 3703E nameplate, hardware revision, chassis and slot, termination model, configured range, quantity and destination.
Send the complete Triconex model, revision, quantity, destination and nameplate photo. Identification and compatibility details will be checked before quotation.
