Dry-Contact Adapters?

Discussion in 'Environment Monitors' started by Jim Loewen, Mar 23, 2023.

    Hi,
    We are needing a monitor that can read a PLC output (dry contact) and send a message via internet.

    I am looking at your Watchdog line and need clarification if that can monitor a dry contact to initiate a message.

    Thanks,
    Jim

    Hello Jim,

    Thank you for reaching out on our HelpCenter.

    Watchdog 15 does not natively support dry-contact probes, unless you use an analog to digital converter.

    There are other environmental monitoring systems that do natively support dry-contact probes - use KVMGFilter to view those which support either 2x, 4x, 5x, or 8x such connections.

    That being said, these systems are designed to work with their own (compatible) probes. If you tell us specifically what dry-contact you're looking to connect, and to which specific system, we could research such potential compatibility for you.

    Hope this helps!
    We welcome your questions - please come back and ask us anything, anytime. You may also give us a call at 1-800-636-3434 for further clarifications on this thread.

    So will this respond to a dry contact closure to trigger an alarm?

    Jim,

    As previously mentioned, Watchdog 15 does not natively support dry-contact probes, unless you use an analog to digital converter.

    Also as previously mentioned, these systems are designed to work with their own (compatible) probes. If you tell us specifically what dry-contact you're looking to connect, and to which specific system, we could research such potential compatibility for you.

    We cannot answer this question without knowing what dry-contact probe you are looking to connect to the Watchdog 15 monitoring appliance.

    Hi,
    The dry contact is just that, a normally open contact that closes to initiate an alarm. Specifically it is a PLC output.

    I need a simple device that the PLC will activate that can send an email or text to an operator.

    Jim,

    There is nothing particularly proprietary about the way our Environmental Monitoring Appliances react to dry-contact probes, but since your 'generic' PLC-output dry-contact probe has never been tested, we cannot guaranty it will perform as expected, although it is reasonable to assume that it would.
