Description
The ABB NTDO02 provides up to eight solid state relay outputs and interfaces with the IMDSO14 Digital Output Module through a cable connection. Each Digital Output Module can have up to 16 output signals for relay control and each of the 16 output signals can control up to nine relays via the NTDO02 termination unit. Up to 18 NTDO02 termination units can be used with one Digital Output Module. If more than one termination unit is used, the additional termination units are interconnected. The controller determines the output state of the termination unit relays.
