Siemens 420 manual Digital output Dout

3 Functions Issue 07/04

3.6.2Digital output (DOUT)

Number:	1
Parameter range:	r0730 – P0748
Function chart number:	FP2100
Features:
- cycle time:	1 ms

Binary states in the drive can be output via the digital output. As result of the fast cycle time, it is possible to control external devices and to display the state in real time. In order that higher powers can also be output, the internal signal (TTL level) is amplified using a relay (refer to Fig. 3-23).

Relay:
- max. opening / closing time:	5 / 10 ms

-	voltage / current			30 V DC / 5 A
				250 V AC / 2 A

The states, which are to be output, are defined using the "BI" parameter P0731 (digital output). For the definition, the "BO" parameter number or "CO/BO" parameter number and the bit number of the particular state should be entered into P0731. Frequently used states including the parameter number and bit are shown in the following Table (refer to Table 3-11).
