EMBEDDED
The actual switching threshold between a zero and a one is between 0.9 V and 2.3 V for all 16 inputs, i.e.
V
IN00-IN13 and IN15 are each fully protected over a range of -36 V to +36 V, and can handle short spikes
of ±40 V. IN14 is protected over a range of -36 V to +5 V.
4.2 DIGITAL OUTPUTS
The BL2500 has eight digital outputs, OUT0-OUT7, each of which can sink up to 200 mA. Figure 6 shows
a wiring diagram for using the digital outputs in a sinking configuration.
+K is an externally supplied voltage of 3.3 - 40 V DC, and should be capable of delivering all the load
currents. Although a connection to a +K supply is not absolutely required with sinking outputs, it is highly
recommended to protect against current spikes when driving inductive loads such as relays and
solenoids.
Connect the positive +K supply to pin 1 of friction-lock connector terminal J10 and the negative side of the
supply to pin 2 of friction-lock connector terminal J10. A friction-lock connector is recommended to
connect this supply because the +K inputs are not protected against reverse polarity, and serious
damage to the BL2500 may result if you connect this supply backwards.
4.3 ANALOG INPUT
The A/D converter, shown in Figure 7, compares the DA0 voltage to AD0, the voltage presented to the
A/D converter. DA0 therefore cannot be used for the D/A converter when the A/D converter is being used.
