3533E | Invensys Digital Input Module

Invensys 3533E Tricon Digital Input Module (Simplex) 24 Vdc/dc 32 points Every Digital Input Module houses the circuitry for three identical channels (A, B and C).Although the channels reside on the same module, they are completely isolated from each otherand operate independently, which means a fault on one channel cannot pass to another. Inaddition, each channel contains an 8-bit microprocessor called the I/O communicationprocessor which handles communication with its corresponding Main Processor.
