Notes on EL2521-0124

The EL2521-0124 has a latch input and a 24 V compare output, which both operate in connection with the position value.

Explanation on the basis of the associated process data:

Latch input, identical function as for EL encoder terminals

• PDO ENC Status (input)
• External latch valid
• Status of extern latch (current state of the latch input)
• Latch value
• PDO ENC Control (output)
• Enable latch extern on positive edge
• Enable latch extern on negative edge

Compare output "PLS" (Programmable Limit Switch)

• PLS Control:
• "Enable PLS":
  = 0 Output can be switched manually via "Output"
  = 1 Automatic switching function has control over the output
• Output
  Switches the output (no function if "Enable PLS" =1)
• Switch on value
  Switch-on value (the output is switched on when the counter reaches this value)
• Switch off value
  Switch-off value (the output is switched off when the counter reaches this value)
