Introduction
The I-7022 is a 12-bit, 2-channel Analog Output module that is designed for both voltage and current output using the DCON protocol. The I-7022 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. The M-7022 and M-7022A supports both the Modbus RTU and the DCON protocols which can be configured via software, and all hardware specifications are the same as the I-7022.
