The 6AG1138-6CG00-2BA0 is a SIMATIC S7-1500 TM Count technology module providing three 24 V counters and one PWM or high-speed output. It handles 26 bytes of input data and 32 bytes of output data, with diagnostic alarms and isochronous mode support for synchronized motion applications. The supply voltage is 24 V DC, with an L+ tolerance of -0.8 V. Signal levels: logic 0 from -30 to +5 V, logic 1 from +11 to +30 V. Maximum jitter is 1 µs, and switching times for the high-speed output are 1 µs rising and falling.
Width 15 mm, height 73 mm, depth 58 mm; BU type A0 base units. Shielded cable up to 1 000 m, unshielded up to 600 m. Input filtering is parameterizable: none, 0.05, 0.1, 0.4, or 0.8 ms. The module supports both 2-wire and 3-wire sensors, as well as 24 V initiators and pulse encoders. It can sink or source current on the high-speed output.
