Module width 30 mm, depth 52 mm, height 81 mm. Per-channel rated current is 2 A; total module current limited to 6 A. Switching frequency: 30 Hz with resistive loads, 0.1 Hz with inductive loads, 10 Hz with lamp loads. Reverse polarity protection is not fitted — verify L+ wiring. Cable runs: shielded or unshielded up to 200 m. Channels are not isolated from each other but are isolated from the backplane bus.","metaTitle":"Siemens 6ES7138-4FB02-0AB0 ET 200SP DQ 4x24VDC/2A SIL3","metaDescription":"Siemens 6ES7138-4FB02-0AB0 SIMATIC ET 200SP digital output module, 4 channels, 2A, SIL3, diagnostics.
