Important Notices
►1: A Zener barrier is not allowed to be connected with this module. Use an isolation barrier when the module is used in intrinsically safe application.
►2: The module input resistance viewed from the terminals depends on the current strength as calculated as below:
►3: When this module is installed to a ER bus node unit with HART function, the EB401 firmware must be rev. 2 or later.
►4: When the dedicated cable is used, the withstanding voltage is 500 V AC (between the input signal and the system). When the ML connector cable is used, the withstanding voltage depends on the electrical specifications of the cable.
►5: This voltage is generated between the connecting terminals for 2-wire transmitters for this module. When calculating the minimum operating voltage for transmitters, consider to allow margins for voltage drop in external wiring.
Buyer: "Miya, our line just stopped. Everyone says the PLC module is obsolete. Lead time is 12 weeks. Help?"
Miya: "Relax. I've got 551,867+ parts in my warehouse. Give me 30 minutes."
(28 Minutes Later)
Miya: "Found it. 100% Brand New, original seal. I've attached a video of the unit and the serial number."
Buyer: "Is it expensive? My budget is tight."
Miya: "I'll give you the factory price. If it's still high, make me an offer. I'm flexible."
Buyer: "How fast can I get it?"
Miya: "Processing takes 1 day. DHL will have it at your door in about 5 days. You want it?"
Buyer: "Send the PI. You're a life saver."
