Manual 35116 505HT for Pelton Turbines
Woodward 36
Hardware - Discrete Inputs
This control provides an isolated group of (20) discrete input channels for use with +24 V (dc) signals. An
isolated Contact Power voltage supply of +24 V (dc) is provided to use with the discrete inputs. This
supply includes short-circuit and over-voltage protection.
Note: Do not use the Contact Power output to power any other devices.
