NOVOSENSE MICROELECTRONICS 4-channel NSI8604 and the 8-channel NSI8608 isolated digital input (DI) chips are suitable for 24V digital signal input in industrial control applications such as PLCs, servos and inverters. Both devices provide input/output isolation when converting voltages in the range of -60V to 60V to logic signals. Products support bi-directional digital input functionality, allowing flexible configuration of system I/O. Unlike digital isolators, the input stage of the chips integrates current-mode input with a function that limits currents to 2.1mA (typical), reducing power consumption and temperature rises in the target system.
