  • Productivity2000 analog input module P2-08AD-1 Glitch

    When you press the little blue button on the P2-08AD-1 analog input 0-20mA module to enable the status screen, the current value momentarily goes high. This is an issue as any logic that is looking at the current measurement is erroneous triggered. We are using the module to monitor a Fire detector loop circuit. See image below for details.

    In the logic, a fire system water deluge solenoid is triggered when the current reading is greater than 12mA. What we found is that when the screen times out and you press the blue button, it momentarily energizes the solenoid dumping the fire system. We've had to add a 2sec timer in the logic to delay the solenoid giving the module enough time to stabilize.

    Please investigate and let me know if you can replicate the problem and if a fix is available. Thanks

    what hardware revision is you P2-08AD-1? It will be the last one or two digits of the serial number on the module label. Could be either A or A1.

        Have you tried swapping the module out with a spare? If needed, call into our RA department to get the P2-08AD-1 replaced.

          We have 6 modules spread out in 1 local base and 2 remote bases (2 per base). They all randomly do that when awoken, so I think it's something common in them. The 2 second delay seems to have fixed the problem in this application but I just wanted to bring the issue to your attention.
