Features
Triple Modular Redundancy:Processes each input through three independent paths and votes on the result to ensure 100% fault-tolerant signal accuracy.
Continuous Self-Diagnostics:Executes sophisticated background tests to detect stuck-at conditions, internal hardware faults, or degraded signal integrity.
Hot-Swap Capability:Modules can be replaced while the system is online and energized, eliminating the need for process shutdowns during maintenance.
High-Density Monitoring:Provides 32 channels in a compact form factor to optimize space within Tricon controller chassis.
Environmental Hardening:Designed to operate reliably in harsh industrial environments with broad temperature and humidity tolerances.
Point-to-Point Isolation:Prevents electrical noise or faults on one channel from affecting adjacent channels or the internal controller logic.
