- 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.

规格参数：

ELECTRICAL

Input Signal Frequency Range: Standard input range is field-selectable from 0–80 Hz to 0–20 kHz. Ranges as low as 0–0.1 Hz and up to 0–50,000 Hz are available options.
Input Signal Sensitivity: Field-adjustable from approximately 5 mVrms to 100 mVrms by internal sensitivity potentiometer.Normal factory setting is 25 mVrms. Maximum permissible signal is 50 Vrms for the standard unit.
Input Impedance: Nearly infinite at low signal levels; a minimum of 10 kΩ at signal levels exceeding +15.0 V peak or –1.0 V peak.
Power: 115 Vac ±10%, 47–420 Hz/22–30 Vdc, maximum 5 W or 150 mAdc. Optional: 220 Vac, ±10%, 50/60 Hz/22–30Vdc.
Proportional Output: 4–20 mAdc. The maximum load is 1kΩ with the unit powered by 115/220 Vac or 30 Vdc; and 750 ohms with the unit powered by 22 Vdc. The maximum load is approximately linear between 22 Vdc and 30 Vdc. Other custom ranges are available.
Auxiliary Meter Output: Proportional 0–1 mAdc, filtered, for meter or recorder loads up to 750 Ω.
Supply Output: Regulated +14 Vdc (±5%), at terminals 11(+) and 4(–); maximum load 40 mAdc.
Repeater Output: Square wave 14 V peak-to-peak, positive going, at terminals 29 and 4 to operate signal-powered digital tachometers SPD-100 and SPD-700.
Output Ripple and Noise: 0.1% of full-scale maximum over 10% to 100% of full-scale.
Verifying Setpoints: No input signal required. Jumpering specific terminals overrides the 0–1 mA auxiliary meter output at terminals 7 and 8; instead, the actual setpoint value is output and viewed using an external meter at terminal 7 and 8.
Response Time: 150 milliseconds, 10% to 90% rise, is standard. Full-scale frequency ranges below 80 Hz are proportionally slower.
Linearity: 0.1% of full-scale (0.05%, typical), all outputs.Output and Setpoint Stability: Less than 0.05% of full-scale change with a 10% change in supply voltage.

RELAYS

Logic: Field-programmable by switches for overspeed,underspeed, energize, de-energize, latch, auto-reset, and DPDT.*
Ratings:

“A” series: Contact rating: 6.0 A @ 28 Vdc or 115 Vac (resistive); 2.0 A @ 220 Vac. Maximum inductive load 75 Vdc, 1.0 A, into 500 mH, for up to 100,000 cycles; SPDT.*

“H” series: Contact rating: 5 A (resistive) @ 24 Vdc; 1.0 A @ 120 Vac; 0.5 A @ 220 Vac; SPDT.* *For DPDT, relays 1 & 3 and 2 & 4 work together as separate DPDT trips.

Alarm Setpoints: Relay setpoints are easily adjustable using 25–turn cermet potentiometers. Potentiometer adjustments are accessible through holes in the cover plate.
ALARM DISABLE: Jumpering terminal 31 to terminal 7 disables all alarms, allowing for startup conditions and special functions.
ALARM RESET: Momentary jumpering of terminal 32 to terminal 7 resets all latched alarms. Permanent jumpering converts all latching alarms to auto-reset.

OPTIONS
ENCLOSURES: XP and NEMA rated enclosures are available.
OPEN PICKUP: Relay 1 switches in the event of an open or disconnected magnetic pickup. Relay 1 will still react when its setpoint is traversed. NOTE: Not available with signal isolation transformer option.

PNEUMATIC TRIP: Pulses relay 1 for 100 milliseconds; trips optional Dynalco SPV-200 Solenoid Pneumatic Valve on overspeed.
UNDERSPEED CLASS “C” LOGIC: Arms relay 2 as setpoint
2 is traversed on increasing speed. Pulses relay 2 as setpoint
2 is traversed on decreasing speed. Use for tripping the
pneumatic SPV-200 on underspeed or for general underspeed electrical shutdown.

EXPANDED SCALE INPUT: Provides full meter output, full proportional output, and full setpoint range over a limited input range e.g. 0–1 mA and 4–20 mA over 800–1000 Hz input frequency.
