Description
The I-7022 is a 12-bit, 2-channel analog output module with an RS485 interface, using the DCON Protocol. It can offer either current output or voltage output, with the power source for the current output can be selected as either internal or external via a jumper. There are options for power on value and safe value, while the I-7022 also features 3000 VDC intra-module isolation.
A wide range of software drivers are available, including a driver for our own Orchestrator package. Please call us for more information.
