Safety wire can provide safety to control systems

AUTOMATED Control and Hengstler will be supplying the ACURO Drive AD37S Safety4Wire, which can provide high levels of functional safety in servo motor control systems.

The interface protocol meets SIL3 requirements according to IEC 61508,Cat 3 PLd per EN ISO 13849, while the AD37S encoder itself and the IP core in the controller both meet SIL2.

With an operating temperature range up to 105C and a 12,000rpm maximum speed, the 28mm mounting depth of the AD37S makes it a compact Multiturn encoder.

The encoder contains both an encoder temperature sensor and an input to allow connection of the motor’s winding temperature sensor, adding that information directly into the encoder’s data. An internal ‘electronic data sheet’ in the encoder stores motor and encoder data and can be recalled at any time.

Automated Control specialises in the national supply of process and automation control equipment to a diverse range of industries that encompass the water, industrial, food, mining and petrochemical markets.

It supplies AMCI, STS, Weber, Pepperl+Fuchs, West Instruments, ASM, Hiquel, Kiepe, Hengstler, Conductix-Wampfler, Monitouch, Rittmeyer, Pulsar and FEAS products.
