It mounts onto a BaseUnit type A0 and communicates via the backplane bus. The module provides 26 input bytes and 32 output bytes, with isochronous mode support for deterministic cycle times. Operates at 24 V DC with tolerance L+ (-0.8 V). The module width is 15 mm. The module includes three counters and one PWM output, with a maximum jitter of 1 µs when using High Speed output. The counter inputs can handle 24 V pulse encoders and 2-wire sensors; signal threshold for “1” is +11 to +30 V, “0” is -5 to +5 V. This makes it a fit for high-speed counting or frequency measurement without a separate counter module. Outputs are parameterizable as standard or high speed, with rise/fall times as fast as 1 µs in high-speed mode. The module sinks or sources current (selectable) and includes short-circuit protection. Total power dissipation is 1.5 W typical, so panel cooling is not a concern even in a densely populated rack.","metaTitle":"Siemens 6ES7138-6CG00-0BA0, ET 200SP 24V I/O, 1µs Jitter","metaDescription":"Siemens 6ES7138-6CG00-0BA0 is a current-production ET 200SP module with 24V supply, 1µs jitter, 15 mm width.
