Compatible Sensors (Understanding Inputs)
Warning
Users must NEVER apply any voltage to an input on PM
series product!
Inputs are for dry contact closures only!
Inputs are capable of reading Contact Closure generating
devices such as buttons and switches. A wire connected
from the ground terminal to the input terminal would
trigger in the input, as this would be considered a contact
closure. Any device that generates a dry contact closure
can be used to trop the inputs on PM series controllers.
Push Notification Inputs play a vital role in the use of a
PM series controller. Before we begin using the controller,
it is essential that users understand the role of these inputs.
Improper use of these inputs can cause Irreparable
Damage to the PM controller.
Power Supply Specifications
PM controllers require a 12VAC or 12VDC power supply to power the logic and
relays of the controller. The PWR12 is our stock power supply suitable for use with
ALL PM Series controllers. While it is possible to operate from an automotive 13.8V
power supply, higher voltages are not recommended. Additional power filtering may
be required for proper operation in automotive electrical systems. The absolute
minimum recommended operating voltage is 11VAC or 11VDC. PM controllers
require approximately 100ma for standby and 60ma for each activated relay.
Communication Modules may require up to an additional 240ma, this is documented
on the Electrical Specifications Page.
Power polarity is not important on the PM Series controllers. There is no positive or
negative terminal. Simply apply power to the controller as it is convenient to make
wired connections. The PM controller will rectify your power supply and attempt to
filter noise to safe levels for proper operation.
