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.

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
