INTODUCTION

The ET-2242U provides 16 sink- or source-type Digital Output channels by wire connection and each channel can drive 500 mA load. There are
configurable power-on and safe values for digital output. With 2 Ethernet ports, the ET-2242U allows daisy chain connection which permits the
flexibility in locating devices, eases installation and lowers infrastructure costs. It features 8 kV ESD protection, 4 kV EFT protection, 3 kV surge and
3000 VDC I/O isolation to enrich the noise protection ability for industrial environment.
