3704E| Triconex| Analog Input Module
Description
The 3704E is a TMR (Triple Modular Redundant) analog input module designed for critical control applications. It features 16 differential, isolated input points and supports both voltage and current inputs. The module converts analog signals to digital values and transmits them to the main processor modules. In TMR mode, it uses a mid-value selection algorithm to ensure accurate data for every scan. The 3704E provides complete, ongoing diagnostics for each channel and supports hot-swap capability for online replacement of faulty modules.
Features
- 16 differential, isolated input points
- Supports 0-5V or 0-10V voltage inputs, selectable via TriStation software
- Supports 0-20mA current inputs with 250Ω or 500Ω shunts
- Mid-value selection algorithm for accurate data
- Complete, ongoing diagnostics for each channel
- Hot-swap capability for continuous operation
- Mechanically keyed for proper installation in a Tricon chassis
- External termination panel (ETP) required for field connections
