Technical specifications

Power supply (SELV/PELV)

Ensure that the power supply is safely disconnected in accordance with the following standard:

IEC/UL61010-2-201 This separation is referred to in the standard as SELV (Safety Extra Low

Voltage) / PELV (Protective Extra Low Voltage).

Make sure that the supply and input voltages of the ET 200SP HA IO device are generated safely

separately:

Nominal value: 24 VDC +-20% (

Cycle time

The cycle time describes the time slice in which new process values are output. The cycle time

of the I/O module is 150 μs.

Response to short-circuit detection

The I/O module is equipped with an overload protection that triggers as of about 2 A. When this

limit is exceeded, the I/O module automatically limits the current (typically: to 1.3 A). If the

overload continues, it results in a temperature increase in the I/O module. The respective output

switches on and off again cyclically (clocked).

Note

Cable length

Ensure sufficient low-resistance cable routing to the sensor/actuators to reach the response

threshold. Depending on the cable cross-section used, there may be restrictions in the cable

lengths that can be used.
