Omron SRT2-OD16 transistor remote terminal 1A 24VDC 16 terminals *new*

SRT2 models support both high-speed communications (750 kbps) and long-distance communications (500 m) systems, switch selected. Two independent power supplies can be used because the I/O terminals are isolated from the internal circuits.
