VSI2, VSI2 Series Signal Isolator 120/240Vac 50/60 Hz.

KEY FEATURES

• Model & Power: VSI2 Signal Isolator, supports 120/240 VAC, 50/60 Hz power supply

• Input Compatibility: Accepts grounded or ungrounded DC input signals ranging from 0–5 VDC up to 0–250 VDC, and 4–20 mA (jumper-selectable)

• Selectable Range: Hi/Lo range jumper for configuring input span – “Lo” for low-voltage or 4–20 mA inputs, “Hi” for higher voltage ranges

• Output Signal: Filtered, pulse-width-modulated output directly proportional to the DC input signal

• Thermal Stability: Built-in feedback circuit minimizes output drift due to component heating

• Isolation: High electrical isolation of 2500 Vrms via optically isolated IC package

• Construction: Aluminum chassis-mount housing with on-board logic power supply

• Application: Ideal for master/follower motor speed control, compatible with any drive with +5 to +15 VDC reference input and impedance >47 kΩ, optional scaling potentiometer for proportional control

The VSI2 provides isolation and signal conversion for applications where drives are connected to supervisory systems such as plc’s and SCADA’s. The VSI2 offers both analog voltage (+5 to +250VDC) and current (4-20mA) signal input capability. These inputs are scaled and sent to the speed pot circuit on any drive that accepts a 3-wire speed pot input.
