CHARM I/O Card (CIOC) and CHARM I/O Card 2 (CIOC2) specifications

Installation notes

The CHARM I/O Cards install on the CHARM I/O Carrier.
The CHARM I/O Cards receive redundant 24 VDC power and generate 6.3 VDC system power for the CHARMs through the CHARM I/O Carrier.
Ethernet cascade ports (primary and secondary) on the CHARM I/O Carrier allow as many as 16 cards (CIOCs and CIOC2s) to be connected together without wiring back to a central switch.
The CHARM I/O Cards communicate with the DeltaV controller through the CHARM I/O Carrier.
The CHARM I/O Cards support redundancy.

Table: CHARM I/O Card and CHARM I/O Card 2 (CIOC2) specifications
Item	Specification
Input power requirement through the CHARM I/O Carrier	0.28 A maximum per redundant CIOC node (CHARM power requirements are additional)
Output power to CHARMs through the CHARM I/O Carrier	3.25 A maximum at 6.3 VDC
Ethernet connection through the carrier	Redundant (primary and secondary) 10/100BASE-TX ports and 100 BASE-FX ports capable of full-duplex operation.
CIOC heat dissipation	8.0 W maximum per redundant CIOC node: 2 W each CIOC 2 W each fiber-optic I/O port or 1.34 W each copper I/O port
Isolation	None. The CIOC is referenced to the incoming 24 VDC return.
Mounting	One or two slots on the CHARM I/O Carrier.
