Digital Output Wiring Example (Open Collector/Drain)
MPC VECTOR Digital non-isolated output signals can drive DC (direct current) devices such as
LED's, relays, indicator lamps, or any device that does not require more than 500mA of current.
Activation of a digital output from the MPC VECTOR provides a low impedance connection to the external
power supply's ground, allowing current flow through the user device.
(Warning: MPC VECTOR Outputs are not relay contacts)
An external 24 VDC power supply must be supplied. Digital Outputs 1-3 consist of an open collector/drain
current sinking low side switch capable of sinking 500 mA. The maximum external voltage that may be applied
to these digital outputs is 40 VDC (see Section 13 Specifications, for more information).
