SST 2000

SST-2000ATM and SST-2000HTM Series Speed Switches/ Transmitters receive signal input from a passive or active magnetic pickup, shaft encoder, contact closure, flowmeter, etc., toprovide proportional analog outputs and either 0, 2, or 4 relay trip setpoints
Proportional outputs of either 4– 20 mA ( standard) , 0– 5 Vdc, or 0– 10 Vdc are field-selectable. Standard 0-1 mAdc meter output included.
Models available with up to four alarm setpoints.
Field-selectable frequency range.
Field-adjustable sensitivity control.
Field-programmable for many types of sensors, including contact closure input.
Repeater output drives counters and self-powered digital tachometers such as Dynalco’ s SPD-100 and SPD-700.
Regulated 14 Vdc output powers active pickups ( e.g. M910) , accessories, and digital meters such as DPM-105 or MTH-103D, and the 12 Vdc versions of the internally lighted SPD-100L and LST-100L.
Alarms are field-configurable for DPDT ( SST-2400 A or -H only) , overspeed, underspeed, energize, de-energize, latch, auto-reset.
Integral VERIFY, requires external meter. Permits viewing and setting of setpoint value without actuating the relays.
Input Frequency: Full-scale values from 0– 0.1Hz ( 6 pulses per minute) to 0– 50, 000 Hz.
Function: Converts frequency input ( speed, rate) into linear proportional dc output. Provides alarm setpoints for over- and underspeed control and for sequential, startup, and shutdown switching.
Applications: Includes engines, machines, I/ P drivers, instrumentation, process control, recording, measurement.
Signal Sources: Includes magnetic pickups, ac generators, contact closures, photocells.
Output Range Capability: Current source up to 50 mAdc output always included.
Alarm Setpoints: Available with two or four relays. Also available with no relays if only proportional outputs are required.
