Racal 1260-14C

Digital I/O Module, Open Collector The Racal 1260-14 digital I/O module provides 96 open collector channels in twelve groups of eight bits each. With the open collector version each independent group can utilize a separate internal or external pull-up supply up to 32VDC. Each channel can be configured as an input or an output and individually controlled in the asynchronous mode, or be synchronous with other channels. The 1260-14 has a two-wire, handshake mode available for the control of synchronous I/O transactions. Each handshake line can be programmed to either active high or active low to provide a flexible interface with user signals. The 1260-14C I/O channels are open collector transistors ideal for controlling external digital circuitry, switches, relays and similar devices. The 1260-14 is programmable in several operating modes and data may be manipulated in either hex, decimal or binary. Memory is available on
