Phase Monitor Bypass
Auxiliary Input and Output Connections
The TCU provides an auxiliary digital input and output that can be configured together to function as an auxiliary relay.
The AUX_IN terminal (P2-12) functions as one side of a relay coil and the IN_COM_2 terminal (P2-14) as the other. The
AUX_PWR terminal (P1-18) and AUX_OUT terminal (P1-19) function as contacts for the relay.
Input commons on the TCU must be either AC neutral (with no voltage potential when referenced to earth
ground) or the negative terminal of a DC power supply.
Auxiliary Digital Input
AUX_IN is an optically isolated digital monitor point and is wired the same as the other monitor points. Connect a bias
voltage to one side of a contact closure device. Connect the other side through a voltage-dropping resistor, if required, to
the AUX_IN terminal (P2-12).
Auxiliary Digital Input
Auxiliary Digital Output
AUX_OUT is a solid-state relay. Power is connected to the AUX_PWR terminal (P1-20). A load is connected between the
AUX_OUT terminal (P1-19) and the power source return.
