WirelessHART I/O Card specifications

Installation notes

The WirelessHART I/O Card (WIOC) installs on the WirelessHART I/O Carrier. The WIOC supports redundancy.
WIOCs require the redundant WirelessHART I/O Energy Limited Terminal Block or the WirelessHART I/O Terminal Block for terminations for wiring to simplex or redundant Smart Wireless Field Links.
WIOCs receive redundant 24 VDC power and condition it to power the Smart Wireless Field Link through the terminal block on the Wireless I/O Carrier.
Simplex or redundant WIOCs connect to the control network through primary and secondary ethernet connections on the WirelessHART I/O Carrier.
Ethernet cascade ports on the WIOC Carrier allow up to 16 WIOCs to be connected together without wiring back to a central switch.
The WIOC communicates with the DeltaV controller through the Wireless I/O Carrier.

Table: WirelessHART I/O Card specifications
Item	Specification
Input power per WirelessHART I/O card	+24 VDC ± 10% at 400 mA maximum
Output power to the Smart Wireless Field Link through the Wireless I/O carrier	+24 VDC at 100 mA maximum
Ethernet connection through the Wireless I/O carrier	Redundant (primary and secondary) 10/100BASE-TX and 100BASE-FX ports capable of full-duplex operation.
WIOC heat dissipation	11 W maximum per redundant WIOC node: 3.5 W for each WIOC 2 W for each fiber-optic I/O port (IOP); 1.34 W for each copper I/O port
HART scan time	8 seconds for 100 devices
Isolation	None. The WIOC is referenced to the incoming 24 VDC return.
Mounting	One or two slots on the Wireless I/O Carrier.
