Auxiliary Power Wiring For Pm-12 Module; Auxiliary Power Wiring For Pm-24 Module - Emerson ROC809 Instruction Manual

PM-24
Revised Nov-10
For the 24 volt Power Input module (PM-24), the AUX voltage is
always 12 Volts dc minus ~0.7 Volts. AUX+ / AUX– is internally
current-limited by a 0.5 Amp Positive Temperature Coefficient (PTC).
If you need to cycle power to the radio or other device to reduce the
load on the power source (a recommended practice when using
batteries), use a Discrete Output (DO) module to switch power on and
off. (The PM-12's on-board AUX
this function.) Refer to the ROCLINK 800 Configuration Software User
Manual (for ROC800-Series) (Form A6218) or the ROCLINK 800
Configuration Software User Manual (for ROC800L) (Form A6214).
