About DO3401 :
TRICONEX DO3401 24vdc
Digital Output Module Each TMR Digital Output Module has three isolated sets of electronics, called channels, which independently accept data from the MP associated with each channel. The channels use the patented Quad Voter circuitry to vote on individual output signals as they are applied to the load. This voter circuitry is based on parallelseries paths which pass power if two out of three switches (channels A and B, or channels B and C, or channels A and C) command them to close. The Quad Voter circuitry has multiple redundancy on all critical signal paths, guaranteeing safety and maximum availability. For each point, the DO Module periodically executes the Output Voter Diagnostic (OVD) routine. To allow unrestricted safe operation under a variety of multiple-fault scenarios, OVD detects and alarms these types of faults: • Points—all stuck-on and stuck-offs are detected in less than 500 milliseconds. • Switches—all stuck-on or stuck-off switches or their associated drive circuitry are detected. DO Modules include complete, ongoing diagnostics for each channel. If the diagnostics detect a failure on any channel, the Fault indicator turns on and activates the system alarm. The Fault indicator identifies a channel fault, not a complete module failure. DO Modules are guaranteed to operate properly in the presence of a single fault and may continue to operate properly with certain multiple faults. DO Modules support a hot-spare module. Each DO Module is mechanically keyed to prevent improper installation in a configured baseplate.
