Siemens SIMATIC Distributed I/O ET 200eco PN Operating Instructions Manual page 188

Properties
• 4 outputs for voltage or current output
• Output ranges:
– ±10 V, resolution 15 bits + sign
– 1 to 5 V, resolution 15 bits
– 0 to 10 V, resolution 15 bits
– ±20 mA, resolution 15 bits + sign
– 4 to 20 mA, resolution 15 bits
– 0 to 20 mA, resolution 15 bits
• Supply voltage DC 24 V
• Dimensions 60 x 175 mm
• Diagnostics
– "Missing 1L+" supply voltage
– "Sensor supply short-circuit"
– "Wire break"
– "Short-circuit"
– "Overload"
• Parameterizable response to CPU/Master STOP
• Prioritized startup
• Media redundancy
NOTE
Incorrect intermediate values at the output are possible when supply voltage 1L+ is
switched on and off.
NOTE
The outputs are in voltage mode and supply a signal 0 V until the parameter assignment
becomes effective after switching on.
