TRICONEX 3664 TMR Triple Module Redundancy Module

I. Product Description
Brand: Schneider Triconex (formerly Invensys)
Type: 32-channel 24VDC high-density digital output DO module (dark blue panel)
Architecture: TMR triple module redundancy, 2oo3 three-out-of-two voting, SIL3 safety level
Compatible systems: Tricon v10/v11 chassis (3700 series chassis), supports hot swapping
Application: SIS safety instruments, ESD emergency stop, fire and gas F&G, combustion management BMS systems, directly drives solenoid valves, cut-off valves, audible and visual alarms, relays and other field actuators

Core Electrical Parameters
Channel Configuration: 32 channels sharing a common negative pole digital output, with each channel being independently isolated
Operating Voltage: Rated 24VDC, allowable 16-30VDC, maximum withstand voltage 36VDC
Current Load
Continuous Output: 2A/channel
10ms Surge Peak: 10A
Total Machine Load < 10W
Maximum Leakage Current: 2mA
Isolation: Channel-to-channel, channel-to-ground board isolation ≥ 1500VDC
Voltage Drop: Typical with load < 1.5VDC
Diagnostic Capability: Real-time detection of short circuits, open circuits, breaks, and load absence for each channel. Faults are reported to the controller within 10ms, and the panel has independent channel fault indicator lights
