I-97028U CR
8-ch Isolated Analog Output Module
The I-97024U and I-97028U are source type analog output modules, which offer 4 and 8 single-ended analog output channels. Every channel can be programmed to an individual output range of 0 ~ 5 V, ±5 V, 0 ~ 10 V, ±10 V, +4 ~ +20 mA or 0 ~ +20 mA. Open wire detection is provided for +4 ~ +20 mA output. Options for configuring power-on and safe values are also included.
The I-97024U and I-97028U provide RF immunity level matching that defined by IEC 61000-4-3 standard, together with 4 kV ESD protection as well as 3000 VDC intra-module isolation
