24 TTL Channels, Programmable I/O
TL1 - North Atlantic Industries (NAI)
Function module TL1 provides 24 channels of TTL/CMOS transceiver functionality as either inputs or outputs. The transistor-transistor logic (TTL) employs transmitters with multiple emitters in gates having more than one input. TTL offers high switching speed and relative immunity to noisy systems. CMOS sensors provide image sensing technology by converting light waves into signals that are small bursts of current. These waves can be light or other electromagnetic radiation.
