EL1252-xxxx is a 2 ch digital input terminal with timestamps (low to high, high to low):
Both terminals have the product id and process data and can therefore be configured as EL1252:
# One channel:
${SCRIPTEXEC} ${ecmccfg_DIR}addSlave.cmd, "SLAVE_ID=16, HW_DESC=EL1252"
These terminals are very powerful since they can latch the time of the positive edge and/or negative edge of the input signal (independent of the ethercat bus rate). These timestamps can then be used to correlated other data, like encoders or analog inputs with timestamps.
IMPORTANT Sine the EL1252-0050 is a 5V terminal, it needs to be powered with 5V if the terminal is powered with 24V, the terminal will burn. The simplest way to achieve a correct power supply is by adding an EL9505 (or similar) before the EL1252-0050. See above for more information 5v-and-24v-terminals
Make sure the EL1252-0050 has a 5V power supply by an EL9505 (or similar), before powering the system. If the terminal is powered with the normal 24V it will most likely break
A 5v signal will not be detected with the 24V version (EL1252), the terminal will however not be damaged. Further more, it’s not a good idea to to power the 24V version with 5V (EL9505, or similar)
