FOUNDATION FIELDBUS

- 5 Discrete Inputs, 3 Discrete Outputs

- Emerson DeltaV, Honeywell, Yokogawa,

Rockwell, Invensys approved

- Pre-deﬁned templates, on-board diag-

nostics, and early warning LEDs

- Consumes only 17mA to operate,

reduces VCRs and DSTs required

- Local calibration button for factory set-

ting of end of stroke switches

- Position feedback via DO read back

reduces number of function blocks.

BEST-IN-CLASS CAPABILITIES

- Reduced number of blocks scheduled

on the segment

- Reduced macrocycle times

- Reduced VCR Links (Publisher/

Subscriber)

- Reduced DST count

- Higher density of valves per segment

- Less segments required per project

(less hardware)

- Pre-Built and Industry Tested Library

Modules (reduced engineering)

- Lower Total Cost of Ownership for

Intrinsically Safe Applications

- ASi 2.1 with up to 4

Discrete Inputs and 3

Discrete Outputs

- Early warning LEDs

- Digital conﬁrmation

of analog signal

- Auto-calibration via

handheld

- Proﬁbus DP V0

- 4 Discrete Inputs

2 Discrete Outputs

- Early warning LEDs

SINGLE DO BLOCK

Using the Readback function in the DO

block for position feedback reduces the

number of DSTs required and allows the

user to switch the solenoid and get posi-

tion feedback via this single DO block.

CALIBRATION SWITCH

The SCM-FF is equipped with a local

calibration button for pre-installation

function testing of the valve actua-

tor package. This ensures that all valve

automators can function test packages

before installation without having to

purchase expensive test equipment.

LEDs indicate correct position setting

of the switches.

PIEZO TECHNOLOGY

TopWorx discrete valve controllers incor-

porate the best piezo technology available

on the market today. With a response

time of under 50mS and a high ﬂow rate,

we ensure the spool valve reacts immedi-

ately to a change in signal.

- 3 Discrete Inputs, 2 Discrete
