Emerson DeltaV™ M-series Traditional I/O Cards

The Traditional I/O subsystem includes:

• I/O interface carrier (a DIN rail surface mounted)

on which all I/O related components are installed.

• Bulk AC to 24V DC power supply for field devices.

 An I/O interface consisting of an I/O card and an

I/O terminal block.

• A variety of analog and discrete I/O cards enclosed

in a common form factor that easily plugs into the

I/O interface carrier.

• A variety of I/O terminal blocks mounted on the I/O interface

carrier that can be pre-wired before I/O card installation.

I/O Cards

A variety of analog and discrete I/O cards are available to meet

your specific requirements. The following cards support simplex

or redundant installation:

• AI 4-20 mA HART 8 channels

• AO-4-20 mA HART 8 channels

• DI, 24V DC Dry Contact, 8 channels

• DO 24V DC High-Side, 8 channels

• AI (Plus) 4-20 mA HART, 16 channels

• AO (Plus) 4-20 mA HART, 16 channels

• DI (Plus) 24V DC, Dry Contact, 32 channels

• DO (Plus) 24V DC, High-Side, 32 channels

The following I/O cards are supported in simplex format

to meet your field wiring needs.

• AI Isolated, 4 channels

• RTD, 8-channels

• Thermocouple, 8 channels

• Millivolt, 8 channels

• DI, High Density, 32 channels

• DI 24V DC Isolated, 8 channels

• Multi-Function, 4 channels (Isolated DI)

• Sequence of Event, 16 channels (DI 24 V DC)

• DI 120V AC Low Side Detection, 8 channels

• DI 120V AC Isolated, 8 channels

• DO 24V DC Isolated, 8 channels

• DO 120/230V AC High-Side, 8 channels

• DO 120/230 Isolated, 8 channels

All I/O cards are enclosed in a common form factor that plugs

into the I/O interface carrier. The housing is clearly labeled with

the enclosed I/O card type. All cards have power and internal

error indicators. Eight-channel cards have clearly visible channel status LEDs.

All cards meet ISA G3 corrosion specifications by the careful

selection of superior electronic components and the use of conformal coating.

Pulse Counters are available on most DI cards. The supported

maximum frequency varies from 0.1 Hz on AC signals to

75 or 120 Hz on 24V DC inputs. For higher pulse counts,

up to 50 KHz, use the Multi-Function card’s high speed pulse input.

The DeltaV system provides control module level time

stamping for log events and alarms. For greater event

resolution, the 16-channel Sequence-of-Events DI card

can provide signal driven events to a resolution of +/- 0.25 ms

per card, or within 1 ms per controller. Please refer to

the Sequence-of-Events PDS for more information on

Sequence-of-Event data collection and system options for this feature.
