signal isolation optocoupler Broadcom ACPL-244-500E dual channel half pitch phototransistor device
Product Overview
The Broadcom ACPL-2x4 series comprises AC-input, dual-channel and quad-channel, half-pitch phototransistor optocouplers designed for reliable signal isolation. Each device features two light-emitting diodes connected inversely parallel, optically coupled to separate phototransistors. They offer high input-output isolation voltage of 3750 VRMS and a typical response time of 2 s. These optocouplers are suitable for applications requiring signal transmission between circuits of different potentials and impedances, including I/O interfaces for programmable controllers, computers, sequence controllers, system appliances, and measuring instruments.
