The 6ES7138-4DA04-0AB0: Single-channel counter slice for the ET 200SP system. One 32-bit input counts up to 100 kHz with selectable filter (200 kHz or 20 kHz). One digital output sinks 500 mA max, rated for resistive loads to 100 Hz. 15 mm wide, 52 mm deep — fits standard ET 200SP base units. Diagnostics via SF LED on group error.
Input and output features
Gate control, synchronization, and latch functions built in. Works with 2-wire sensors and 24 V initiators; signal‑1 threshold is L+ (-1 V) typical at 9 mA. Output short-circuit protection triggers between 2.6 A and 4 A. Reverse polarity protected. Power loss typ. 1 W.
