Model 3806E and Model 3807 modules optimize turbo-mechanical control. The model 3806E High Current AO module has two servo-actuators with 20 to 320 mA output drives. Model 3807 Bipolar AO module has four -60 to + 60 mA output drive servo coils for servo control applications. Termination Panel Model 3807 contains four hardwired coils for diagnostic input. Is the Model 3807 designed for control applications Only, applications should not be used safely.
Designed for the most critical applications, the monitor Digital Output (SDO) module meets the needs of a system whose output remains in a single state over a long period of time (in some areas of the application, for years). The SDO module receives output signals from each of the three main processor channels. Each group of three signals is then voted on by a fully fault-tolerant person. The four-fold output switch element has a mechanical power relay, and a voting output signal passes through to the field terminal. Each SDO module has voltage and current loopback circuit coupling
Sophisticated online diagnostics verify the presence of each output operating switch, field circuit and load. The design provides full fault coverage needed to affect the output signal. These modules are called “supervisory” modules.
Because fault coverage is extended to include potential field problems. In other words, the field circuit is overseen by the SDO module so that the following field failures can be detected:
• Power failure or blown fuse
• Turn on or lose load
• A short circuit causes the load to be powered on incorrectly
• Short-circuit load when the power is off
Unable to detect any field voltage output point for the power alarm supply indicator. The load alarm indicator cannot be detected. When an optional auxiliary component power supply is in use, the short-circuited load enters a state that can be detected as Off. (No 3611E AC module is provided on this model.) All SDO modules support hot spare capabilities, which require a separate cable interface from the external terminal panel (ETPTricon backplane).
