Installation notes
- The WirelessHART I/O Carrier installs on horizontal T-type DIN rails.
- WirelessHART I/O Cards (WIOC) plug into the slots on the WirelessHART I/O Carrier.
- Redundant WirelessHART I/O Energy Limited Terminal Blocks or WirelessHART I/O Terminal Blocks install on the WirelessHART I/O Carrier for terminations for wiring to simplex or redundant Smart Wireless Field Links.
- The WirelessHART I/O Carrier provides redundant 24 VDC power for the WIOC. Refer to the image Figure: Powering the WirelessHART I/O Carrier for information on powering the WirelessHART I/O Carrier.
- The WirelessHART I/O Carrier houses a primary and secondary I/O Port (IOP). There are two types of IOPs: a copper IOP and a fiber-optic IOP. The copper IOP consists of a control network port and a cascade port. The fiber-optic IOP consists of a control network port only. The I/O ports are removeable. To remove an I/O port, depress the button next to the I/O port and pull the I/O port out of the carrier. Refer to the image Figure: Connectors on the WirelessHART I/O Carrier for the location of the IOPs on the carrier. The image shows a carrier with copper IOPs.
- Copper Ethernet cascade ports (primary and secondary) on the WirelessHART I/O Carrier allow up to 16 WIOCs to be connected together (daisy-chained) without wiring back to a central switch. Fiber-optic I/O ports can be used for remotely located WIOCS . WIOCs with a fiber-optic port cannot be daisy-chained and are used in star-connected networks.
- Redundant WIOCs connect to the control network through primary and secondary ethernet connections on the WirelessHART I/O Carrier.
