SITOP CNX8600 8x2.5 A expansion module for PSU8600 Output: DC 24 V/8x 2.5 A outputs according to NEC Class 2 The SITOP CNX8600 expansion modules are part of the SITOP PSU8600 modular system and expand the basic device in the number of selectively monitored outputs. Up to four CNX8600 expansion modules can be connected to a PSU8600 basic device in any combination. The connection is made on the top of the modules without any wiring effort via the System Clip Link, a connector for system data and power supply. The PSU8600 power supply system with complete TIA integration sets new standards in terms of system reliability and efficiency.
