Carlen Controls - Service, Repair, Design of Feedback Transducer Systems for Mill Automation in Roanoke Virginia

GENERAL

The CC451AEMT Multiturn Absolute Encoder is used as a position feedback device where absolute measurement is required. It is a rugged electrical device and does not contain any shock-sensitive component, such as glass scales.

The maximum resolution per turn is 16 bits (65536 positions) at 4096 turns, standard coding for the output is Natural Binary or Gray Code. A reset input is provided to electronically set the position of zero. Information is formatted as serial (RS-232, RS- 422, RS-485 or SSI) or as a parallel 28 bit word. The output can be customer programmed over the RS232 port by using Hyperterminal over an arbitrary number of turns (or fraction of turns and any number of counts per turns). In RS-485 mode, the encoder is addressable to allow operation of up to 32 units over a single I/O line.
