The following types of AI modules are available for SR use in NPPs:
• Model 3721N (AI 6256) is a TriStation configurable 0-5 VDC or -5-+5 VDC analog input
module with 32 differential DC-coupled inputs. The model has a +6 percent over-range.
The 3721N uses the NG common core.
• Model 3701N2 (AI/NITC 5661) is a 0-10 VDC analog input module with 32 differential
DC-coupled inputs. It is equivalent to the 3701N approved with the Tricon V9 platform,
but has been implemented with surface mount components. The 3701N2 hardware and
software were re-qualified for the Tricon V10 platform.
• Model 3511N (PI 5647) is an 8 channel, non-commoned pulse input module with 16 bit
resolution and +/- 0.01 percent accuracy from 1-20 kilohertz (kHz). It is based on the
3510N approved with the Tricon V9 platform with the same specifications except update
rate has been improved from 50 msec to 25 msec, worst case. This pulse input module
is optimized for measuring speed of rotating machinery. It does not have totalization
capability.
• Model 3703EN (EIAI/ITC 5916) is a 0-5 or 0-10 VDC isolated AI module with 16
differential isolated inputs. This module has a selectable voltage range and upscale or
downscale open-input detection and a +6 percent over-range measurement capability.
Model 3703EN was approved for use with the Tricon V9 platform and was qualified with
the Tricon V10 platform.
• Model 3708EN (EIAI/ITC 5916) is an isolated thermocouple input module with 16
differential isolated inputs. This module can support thermocouple types J, K, T, and E,
and can be programmed to provide upscale or downscale burnout detection. In addition
to the Pass/Fault/Active indicator lights, this module has an indicator light that shows a
failure of a cold-junction transducer. Model 3708 EN was approved for use with the
Tricon V9 platform and was qualified with the Tricon V10 platform.
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).
