Signal Circuit of encoder
1. The NPN Open Collector -- The NPN Open Collector(NPN) is an
interface based on an output circuit with an NPN transistor.
An open collector is the unconnected collector connection of an NPN
transistor, whose emitter is connected to earth and whose collector
is connected to the output.
2. PNP output
The PNP output is an interface based on an output circuit with a
3. Push-Pull output(HTL)
High Voltage Transistor Logic functions with a voltage supply in
the range 10 and 30 V DC, with 24 V DC being the most usual.
“Low” is defined as an output of between 0 V and 3 V and “high” as
between VCC and VCC - 3.5 V.
4. TTL RS-422 output
In a transistor-transistor logic (TTL), both the logical status and
the amplification are done by transistors, hence the name.
The TTL output is supplied with either a fixed 5 V voltage or a
variable voltage of between 10 and 32 V. For this the low range is
defined as the ≤ 0.4 V and the high range as ≥ 2.4 V.
