FTA Type Description
240 Vac Digital Input (DI) Similar to the 120 Vac DI FTA, except it has a higher operating voltage and a lower
sense current. The inputs are in four groups of eight circuits with a common return
for each group. Groups are isolated from each other.
24 Vdc Digital Input (DI) Accepts contacts grouped with an isolated common return. Two versions of the
FTA are available, with and without pluggable input modules.
120/240 Vac Solid-State
Digital Output (DO) Provides solid-state ac digital outputs that are isolated from each other and the
HPM.
3-30 Vdc Solid-State
Digital Output (DO) Provides dc power digital outputs that are isolated from each other and the HPM.
31-200 Vdc Solid-State
Digital Output (DO) Provides dc power digital outputs that are isolated from each other and the HPM.
24 Vdc Nonisolated Digital
Output (DO) Provides nonisolated digital outputs to loads such as lamps and relays. The
signals are referenced to logic common.
24 Vdc Isolated Digital Output
(DO) Provides isolated digital outputs to loads such as lamps and relays. The signals
are not referenced to logic common.
120 Vac/125 Vdc Relay
Digital Output (DO)
Provides independent electromechanical relays for ac or dc digital outputs.
240 Vac/125 Vdc Relay
Digital Output (DO) Provides independent electromechanical relays for ac or dc digital outputs.
Pulse Input (PI) Accepts eight inputs, each with a 32-bit counter, and have a frequency range of dc
to 20 kHz. The inputs are referenced to logic ground.
Serial Device Interface
(SDI Toledo) The SDI FTA provides an EIA-232 (RS-232) asynchronous serial communications
interface for a model 8142-2084 or 8142-2184 Toledo Weigh Cell peripheral
manufactured by Toledo Scale Inc.
Serial Device interface
(SDI M/A Station) The SDI FTA provides an EIA-422/485 (RS-422/485) asynchronous serial
communications interface for up to four model MU-MASX02 Manual/Auto Station
peripherals manufactured by Honeywell Inc.
Serial Device interface
(SDI UDC 6000) The SDI FTA provides an EIA-422/485 (RS-422/485) asynchronous serial
communications interface for up to four UDC 6000 Modbus peripherals
manufactured by Honeywell Inc.
Serial Interface
(SI Modbus RTU) The SI FTA provides either an EIA-232 (RS-232) asynchronous serial
communications interface for one Modbus compatible device or an
EIA-422/485 (RS-422/485) asynchronous serial communications interface for up to
15 Modbus RTU compatible devices.
Serial Interface
(Allen-Bradley) The SI FTA accommodates a single EIA-232 compatible Allen-Bradley device
through its EIA-232 interface.
