The new photocoupler’s specifications include both the minimum and maximum values of its threshold input current at its operating temperature range (-40 to 105℃). Use of the photocoupler in combination with appropriate resistors for current control realizes a 24V digital input module that follows IEC 61131-2 Type 1 specifications.

In addition, the new product’s circuit suppresses chattering noise so that its output is clearly either “low” or “high,” even with a slow input signal with a long (60s or less) rise or fall time. This eliminates the need for a waveform shaping circuit in the output part, reducing the number of components.

The photocoupler is packaged in the thin 5pin SO6, and has a maximum height of 2.3mm. Its slim shape brings greater freedom to component layout on printed circuit boards.
