Voltage to Frequency Module
VTF230-XXX

D.C. Power Input

• 24 VDC ±10%, 150mA max, internally fused

Isolation Voltage

• 500V (DC or AC Peak)

Linearity

• ±0.5% of 10 VDC span

Signal Input

• Square wave
• 0 to 50kHz
• 10-90% Duty cycle

Signal Output

• Voltage Output

Selected by position V on J1. This circuit allows the output to source a voltage level of up to ±12 VDC into a minimum resistance of 600 Ohms. If resistance is too low, output linearity may be affected.

• Current Output

Selected by position I on J1.  This circuit allows the output to source a regulated current of up to ±20mA into a maximum resistance of 500 Ohms. Using the BIAS pot, the output can source a 4 to 20mA signal.

Temperature Range

• 0-55ºC
