SSR Module Switches Unbalanced RS-422 Data Pairs

Designed to switch unbalanced RS-422 data pairs, Model 12951 solid-state matrix is non-blocking and features full fanout to allow an input to be simultaneously connected to any combination of outputs. Data interfaces within the 8-in x 12-out x 2-wire solid-state relay (SSR) module are standard RS-422 line receivers and line drivers for full dc to 10 Mbps, 100 ohm compatibility. Up to eight modules can be mounted in the firm's Model 11600/13137 RETA chassis to provide an RS-232/IEEE-488/keypad interface.
