Module RS-485 DCON 1 kênh đầu ra tương tự ICP DAS I-7021P
Introduction
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.
