The 3511 TRICONEX pulse input module and baseboard each dual system consists of = main processor MP) modules, all of which are on a baseboard, and each MP module acts as a channel = remount system, for details, see page 25. The Communication Module and Baseboard Communication Module (CM) is a three-to-one interface MPS that allows the use of industry standard communication protocols. A single triple controller can support up to two CM operating independently on a CM baseboard. The two CMs can provide several communication connections or separate communication ports. For details, see page 27, Analog Input Module and substrate for each mode input (AJ module has three separate channels, each handling analog input devices from the field. Each channel transmits data to the MP associated with the channel. Lawmakers vote on the data before passing it to the application table

3511 TRICONEX Pulse Input Module Each TMR digital output module has three isolated sets of electronics, called channels, that independently receive data from MP associated with each channel. These channels use a patented four-way voter circuit to vote on a single output signal applied to the load. This voting circuit is based on parallel series paths that transmit power if two of the three switches (channels A and B, or B and C, or A and C) command them to close. The quadruple voting circuit has multiple points on all critical signal paths, guaranteeing safety and maximum availability. The DO module periodically executes the Output Voter Diagnostics (OVD) program.
The 3511 TRICONEX pulse input module in order to allow unrestricted and safe operation in a wide variety of conditions, OVD detects and alerts these types of failures: point-to-point all the cards in the on and the cards in the off position are detected in less than 500 milliseconds. Switch 1 Detects all switches or their associated drive circuits stuck at position 0n or position 0. The DO module includes complete, continuous diagnostics for each channel, and if the diagnostics detects a channel on any channel, the noise indicator lights up and activates the system alert. The DO module is guaranteed to operate normally in the event of a single fault and to continue to operate normally in the event of some multiple faults. Module Specifies whether the module supports the hot spare disk module. Each DO module is secured with mechanical keys to prevent improper installation in the configured substrate.
3511 TRICONEX Pulse Input modules These baseboards can be used with Type 3401 DO modules: Type 2401 for typical applications. Model 2401L for low current applications requiring integral current limits. Each output is equipped with a 180 ohm series positive DO external terminal substrate, with relays in kV applications to output the external terminal panel, or type 9671-610 DO hazardous site external terminal panel.
