Note
An additional port (Port 3) is available if needed through the installation of an option card at J14.
2.7.2Digital I/O
The Digital I/O can be configured as either digital inputs or digital outputs as determined by the
Digital I/O menu (see Section 3.6.5 on page 36). The inputs are active (on) with low voltage (0 VDC) and can be
driven by TTL or 5V logic without additional hardware. Use the Digital I/O menu (see Section 3.6.5 on page 36)
to configure the digital inputs. LEDs on the CPU board light when digital inputs are active (see Figure 2-5).
Digital outputs are typically used to control relays that drive other equipment. Outputs are designed to sink not
source, switching current. Each output is a CMOS circuit, capable of sinking 24 mA when active. Digital outputs
are wired to switch relays when the digital output is active (low, 0 VDC) with reference to 5 VDC supply. LEDs
on the CPU board light up when the digital outputs are active (see Figure 2-5).
