AC / DC Power Connections
NOTE: Connect power only after other connections are finished. Do not touch the live AC power terminals! The unit has been
designed with an isolated AC input. Thus, polarity is not a concern for the AC input. Connect AC power to pins 11 and 12. The chassis
is plastic, therefore earth ground is not used. For D.C. operation, c 12V to pin 7 and - D.C. to pin 8.
Sensor Connections
These diagrams show how to hook typical input sensors to the unit. The unit supplies an unregulated 12 Volt (50mA) output to power
these sensors (Pin 7).
A valid pulse is one which makes a transition from the off-state (0 to 1V) to the on-state (4 to 30V): a positive going edge. The input
impedance is 10K Ohms to ground. The unit can be programmed from the front panel for slow switch closure inputs up to 40Hz (select
"Lo CPS"), or solid state switches (select "hi CPS") up to 9.99KHz. No rear terminal jumpers are required. Use PNP (sourcing) type
pulsers.
