Table 2-3. Low Voltage Input Specifications
Note 1: The input current specifications are for 1 module, measured with the
other power supply input disconnected. With both power supply inputs
connected, input current will never exceed the maximum specification, however
the two power supplies do not load share internally.
Internally Generated Limited Power Supplies
Configurable Input Power Supply (24V_AI)
Output Voltage 24 Vdc ±10%
Current Limit 50 mA
Table 2-4. Configurable Input Power Supply Specifications
Avoid using the Configurable Input Power Supply to power any
analog input channels. It is intended for use with inputs that are
configured for discrete mode only.
Relay Output Power Supply (24V_P)
Output Voltage 24 Vdc ±10%
Current Limit 500 mA
Table 2-5. Relay Output Power Supply Specifications
Each ProTechTPS module will function normally with power sourced to both or
either power supply input independently, however Woodward recommends that
both input power sources be used to improve system availability. Please refer to
Table 1-1 for available ProTechTPS models.
