Triconex 3805E Key features
Triple Modular Redundancy with voting ensures reliability under failures
Built-in channel diagnostics with independent loopback feedback
Hot-swappable design allows replacement without system shutdown
Over-range and load detection protect against open-loop conditions
Externally powered loop ensures consistent 4–20 mA output
Performance comparison
Parameter | 3805E | 3804E | 3806E |
Output Channels | 8 | 4 | 6 (4–20 mA) + 2 (20–320 mA) |
Output Range | 4–20 mA (+6%) | 4–20 mA | 4–20 mA + 20–320 mA |
Resolution | 12 bits | 12 bits | 12 bits |
Over-range Protection | Yes | Yes | Yes |
Summary:
The 3805E provides 8 output channels with high redundancy. The 3806E offers higher current (20–320 mA) for turbo machinery, while 3804E delivers fewer points (4-channel) with same robust features
