Eaton Adds Two New High-Performance, SIL 2 and 3 Compliant
SFX Controllers for Off-Highway Electro-hydraulic Applications

EDEN PRAIRIE, Minn. … Diversified industrial manufacturer Eaton Corporation today announced that it has added two new, high-performance controllers to its F(x)™ electro-hydraulic product portfolio. The new SFX 1000 and SFX 2000 controllers offer higher operating speeds than Eaton’s EFX controllers, and meet Safety Integrity Level (SIL) 2 and 3 requirements of the off-highway industry. Typical applications for the new SFX controllers include excavators, forestry equipment, telehandlers, utility vehicles, cranes, agricultural machinery, paving equipment, and other specialty vehicles.

“These new controllers are specifically designed for applications where control loop times are critical,” said Eaton’s A.J. Smith, marketing manager – strategic programs. “In addition, both the SFX 1000 and SFX 2000 controllers have an internal Freescale HC 908 ‘watchdog CPU’ and monitoring software that allows them to comply with the IEC 61508 safety standard. When used as stand-alone controllers they meet SIL 2 requirements for off-highway vehicle applications.”

“The SFX 2000 has an additional TTP (time triggered protocol) controller that enables deterministic network bus communications,” Smith added. “With this capability, a customer can network two SFX 2000 controllers together in an electro-hydraulic application and achieve SIL 3 certification.  SIL 3 is important because new technologies that have a higher degree of risk like steer-by-wire will want to achieve SIL 3 compliance.”

SFX 1000 specifications include:

• A 40 MHz, MPC 555 processor

• 448 kB of internal flash memory

• 26 kB of internal random access memory

• 512 kB of external random access memory

• 2 MB of external flash memory

• 16 kbit EEPROM

• 1 RS-232 and 1 LIN serial interface

• 2 CAN, 125 to 500 kbit/s

• A variety of analog and digital I/O

• Internal monitoring of board temperature and sensor supply and battery voltages

• An injection molded aluminum housing, with splash-proof connectors, pressure adjusting water barriers, and cooling fins

SFX 2000 specifications add to these:

• An option for 1 MB of external random access memory

• 1 TTP bus with redundant channels

• An AS 8202 NF TTP communication controller

Both of the new SFX controllers are programmed via Eaton’s intuitive CONTROL F(x)® programming software.
