I/O Settings
The Logic-5000 supports the following I/Os:
Logic 5000 Input Status: Ignition sense, main voltage, and modem temperature
Four general purpose external analog input lines (AIN1 … AIN4)
Four general purpose external digital input lines (DIN1 … DIN4)
Four general purpose external digital outputs (relay-driven contact closures).
Implemented as four sets of SPST contacts (normally open) (NO1a … NO4b)
See Figure 35 for pin output diagram.
Figure 35 -
Logic-5000 Pin-output. View looking into device.
Digital inputs are internally biased high. To trigger a digital input, connect the pin to
ground.
When digital outputs are triggered, the
a
and
b
pins are connected via an internal relay.
The internal relays are rated for 1A @ 30V, or .3A @ 125VAC.
