Module-IO14A

This modules provide 3x analog input channels (current), galvanically isolated both channel-to-channel and from the electronics; 1x analog output channel (current), galvanically isolated from the electronics; 8x digital input channels (10–30 VDC, including 2x counters up to 5 kHz), optically and galvanically isolated from the electronics; and 2x relay output channels, galvanically isolated both channel-to-channel and from the electronics. The digital inputs also support counter functionality.
