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.
