I-7021/I-7021P/M-7021A
1-channel 12/16-bit, Analog Output Module
 
    ~ Available soon ~
Model: I-7021 Model: I-7021P Model: M-7021A
 
The I-7021 is a 12/16-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. The M-7021A 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-7021.
