4057 PULSE MULTIPLIER/DIVIDIER/K-FACTOR SCALER W/ OPTIONAL ANALOG OUTPUT PA-50 PRODUCT DESCRIPTION The 4057 is a user programmable pulse multiplier, divider, or K-factor scaler. An optional analog output converter can be included, which requires no external test equipment for setup. Output modes are quickly selected via a backlit LCD screen and push-button dial. Models are available for inputs from magnetic VRS, RF, digital amplified pickups, proximity sensors/switches, and other square wave sources. Removable terminal blocks can be factory configured for back panel or control panel mounting. The input frequency can be either multiplied or divided by a user selectable integer. The optional analog output can provide either a voltage or current signal with both minimum and maximum set points adjustable. To multiply by a decimal value (e.g. 10.123) please see the 4057D Bulletin. Push-Button Dial Input Type/Sensitivity: VRS (Mag): 5, 12, 30, 50 or 100mVpp RF: 4 or 10 Ohms Digital: CMOS, TTL, 0-30V, or PNP Frequency Input Range: Digital Output Options: Multiplier Options*: Range: 2 to 50,000 (Integers only) (only up to 80 kHz max frequency) Divider Options*: Range: 1 to 999,999,999 (Integers only) Pulse Width: 1 µs to 10s (frequency dependent) Removable Terminal Block (Back Panel Mount Shown) *NOTE: Not suitable for timing or synchronization applications with current Revision D Firmware. This is due to repeatability limitations with pulse width fluctuations from regular VRS/Mag, Hall Effect, and Digital sensors. Revision E Firmware is in development. Please contact factory. Analog Output Options: FTV Outputs: 0-5V or 0-10V ±0.01 % FSR typ. ±2 ppm/°C output drift FTC Outputs: 4-20mA, 0-20mA, or 0-24mA ±0.01mA Back Panel Mount Control Panel Mount .7in 17mm (Both Minimum and Maximum frequencies are adjustable) Operating Temp.
