Emerson DeltaV™ M-Series Product Description

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.
