Altronix PDS16CB dual input power distribution module is designed to steer the power from either two (2) low voltage AC or DC power sources. The two Inputs can be either both DC (e.g. 12VDC and 24VDC) or both AC (e.g. 16VAC and 24VAC). That power is distributed over a total of sixteen (16) PTC protected outputs. The spade connectors allow you to daisy chain multiple PDS16CB modules. This feature allows you to distribute the power over more outputs for larger systems.
