Introduction 6
Features
The ES1337.2 Signal Generator Board has four independent signal generators
for generating various sensor signals. The following types of sensor can be
simulated:
• Passive analog sensors with a sinusoidal output signal (type “DF6”)
• Active digital sensors with a current interface with two current levels
(type “DF10”)
• Active digital sensors with a current interface with three current levels
and forwards/backwards coding (type “DF10-RotDir”)
• Active digital sensors with a current interface with two current levels
and additional information (type “DF11i”)
• Active digital sensors with a current interface with three current levels
and additional information (type “VDA”)
In addition, there are two other galvanically isolated analog voltage outputs.
The ES1337.2 Signal Generator Board has the following features:
• Four identical, galvanically isolated signal generators for generating
speed signals
• Outputs: ±10 V and 0...40 mA with 10-bit resolution
• Two identical, galvanically isolated analog outputs:
– ±10 V with 10-bit resolution
– Configurable reference voltages (internal/external)
• Every channel is protected against overvoltages to ±60 V
• All outputs with a cut-off relay
• Stand still detection (DF11i, VDA) is supported
• Mixed sensor configurations possible
The following figure shows the front panel of the ES1337.2 Signal Generator
Board with
• the LEDs (see "LEDs" on page 23)
• the port for the signal outputs, signal grounds and external reference
voltages (see "“OUTPUT 0-5” Signal Outputs" on page 21).
• the “SYNC” port (see "“SYNC” Port" on page 22) for outputting a
synchronization signal (“tooth 0”), for example to an oscilloscope.
