Accessories HL553 - Impulse Distributor & Optocoupler - Tag Heuer Professional

We recommend the use of optocoupled impulse distributors for the following reasons: • Controls false triggering due to electronic interference on your timing connection wires. • Completely isolates your timing electronics to ensure that systems operating in parallel (back up) are not linked in any way to each other. The HL 553 Impulse Distributor houses two optocoupled control circuits that are totally separate in terms of electronic parts and power supplies. Each circuit has one input that triggers two isolated outputs.
