NUCLEAR response time monitor

---

• 6 individual channels.
• Mature hardware gate logic design, involves no programmable devices, and no software.
• Each of 6 response time monitors is displayed in numerical form. Each channel has numerical display for the elapsed time and status LED Indicators. 
• Redundant power supply with status indicator.
• Alarm time can be set by digital BCD switches.

Tyne's Response Time Monitor is designed to measure the actuator response time from 'Start' signal to 'Feed back'. It also provides an alarm when the response time is over the limit.

The circuit is designed with a hardware logic integrated circuit. No software is used. The display comprises four 7-segment LEDs to display from 0.01s to 99.99s. The setting is established using BCD switches with displayed numbers. Once the unit detects a "Start" pulse, it begins counting until the "Stop" pulse is received. The count is compared to the setting of a digital comparator. When the count has exceeded the setting, the alarm trips and sends the output to the terminals.
