 GE IS220PDIOH1B Discrete I/O Module The power distribution board shall be powered using the wiring harness specified in the MarkVe and MarkVes Control System Equipment for Hazardous Locations Instructions Guide and powered by a switch mode power supply applicable to the location. When two UL listed power supplies are used for redundancy, the same manufacturer and model shall be used. In the event that no power supply provides reverse protection, a certified diode block accessory shall be used for reverse protection between the power supplies. The current carrying capacity provides individual overcurrent protection, but the protection current for each conductor shall not exceed 15A. Power for Ethernet switches, controllers, and I/O modules shall be provided through a power distribution board that limits the available current to a maximum of 3.5 amps and is certified for use in applicable classified locations.Frequently asked questions about the product are as follows: -What is the function of the IS220PDIOH1B module?
