5.3.6.1BPL010-502 - PNP outputs

An external supply (typically 24VDC) is used to power the UDN2982 output devices, as shown in Figure 22. When an output is activated, current is sourced from the user supply through the UDN2982, which can source up to 75mA per output (all outputs on, 100% duty cycle).

Connect OUT COM to the user supply GND. This will connect internal transient suppression diodes on all outputs. If an output is used to drive a relay, a suitably rated diode must be fitted across the relay coil, observing the correct polarity (see Figure 24). The use of shielded cable is recommended.

5.3.6.2BPL010-503 - NPN outputs

An external supply (typically 24VDC) is used to power the UDN2803 output devices and drive the load, as shown in Figure 23. When an output is activated it is connected to USR COM through the ULN2803, which can sink up to 150mA per output (all outputs on, 100% duty cycle). Connect OUT COM to the user supply 24V. This will connect internal transient suppression diodes on all outputs. If an output is used to drive a relay, a suitably rated diode must be fitted across the relay coil, observing the correct polarity (see Figure 24). The use of shielded cable is recommended.
