The Dytran model 4020 is a µprocessor controlled 3–channel signal conditioner for both charge mode and IEPE sensors. When used with charge mode sensors, the model 4020 incorporates a charge amplifier and when used with IEPE sensors, units incorporate an integral 4 or 10 mA, user selectable, current source with 20 VDC compliance voltage. A user friendly interface allows programming input sensitivity and output sensitivity, then allowing the instrument to calculate the amplifier gain. All gain selections are stored in non–volatile memory and reinitialized when power is applied. Gain can also be entered directly if desired.

For each channel, the model 4020 uses 12 bit DACs to set amplifier gains from 0.00 to 999.9 with 0.5% precision. Amplifier gains can be changed on–the–go without damage to the instrument.

A rear panel voltage selector switch allows selection of 100, 115 230 VAC, 50–60 Hz, input power.
