Product Overview
Emerson A6312-8 is the 8TE version of the dual-channel Speed and Key Monitor specified for use with AMS 6500 systems.
The module monitors speed, phase/key, zero speed and direction of rotation from two independent eddy-current inputs. Official specifications include a 0–20 kHz input range, up to 65,535 rpm and configurable redundant tachometer switchover.
Key Functions
Speed and Direction Measurement
Processes pulse trains from a toothed wheel, keyway or gear to measure forward/reverse speed and detect rotation direction.
Key and Zero-Speed Monitoring
Accepts phase/key signals and configurable zero-speed timing for supported machine-protection applications.
Redundant Tachometer Mode
Can switch from a primary to a backup tachometer when the documented gap-voltage and pulse-comparison conditions are met.
