SITOP CNX8600 8x2.5 A Extension module for PSU8600 Output: 24 V DC / 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 number of selectively monitored outputs of the basic unit. Up to four CNX8600 expansion modules in any combination can be connected to a PSU8600 basic unit. The connection is made on the top of the modules without involving any wiring work using the System Clip Link, a connecting plug for system data and energy supply. The PSU8600 power supply system with complete TIA integration sets a new standard for system reliability and efficiency.
