EX1200-7416

Comparator

The EX1200-7416 is a 16 Channel Comparator/Event Detector with up to 96 differential channels per full rack mainframe

• Up to 96 differential channels per full rack mainframe
• Constantly monitor input signals for fault conditions
• Flexible configurations for detecting edges, out-of-bounds conditions and measuring pulse widths
• Inputs can be masked, inverted, and combined to produce interrupts
• Can be used as a time stamp module and as a digital I/O
• Programmable debounce circuitry prevents erroneous readings
• 10 V and 100 V input ranges
• On-board memory stores events with IEEE 1588 timestamps
• Synchronize reading of input states with other scanned analog channels

The EX1200-7416 has sixteen true differential channels of analog comparator input that can be selected to provide an interrupt to the EX1200 system when the input falls outside the software programmed bounds, independent of the scan list operation. The EX1200-7416 is an ideal device in “go/no-go” testing, where a device fails if the voltage outputs exceed a threshold or window, or in control applications where a device or test needs to be shut down if a voltage level is exceeded. Using an analog comparator/interrupter in certain applications, as opposed to a traditional scanning approach, considerably improves the overall response time of the system, providing the ability to ‘constantly monitor’ signals of interest for fault conditions.
