Introduction

The I-7021 is a 12-bit and I-7021P is a 16-bit, 1-channel Analog Output module that is designed for both voltage and current output. The I-7021 features 3000 VDC intra-module isolation and the power source for the current output can be selected as either internal or external via a jumper. Options are also provided to allow power-on and safe values to be set. Both support the DCON protocols which can be configured via software.
