It is purpose-built for the PCS7 MTA (Marshalled Termination Assembly) architecture, where analog signals from the field terminate on a connector strip inside the enclosure and are routed as a bundled round cable to the PLC rack. The cable is 3 m long, black PVC-sheathed, with a 7.6 mm outer diameter over bundled single cores. Each conductor is 0.5 mm² (roughly 20 AWG), adequate for the 24 V signal levels the system runs — the rated value is 24 V, with a maximum of 30 V. That 30 V ceiling means this assembly is strictly for low-voltage control and analog signal wiring, not for power distribution. The field-side termination is a connector strip (the MTA marshalling panel); the enclosure side uses a screw-type terminal block on the D-SUB connector. This matches the standard S7-300 wiring practice: field wires land on the removable front connector, and the pre-assembled cable carries the signals to the remote I/O station. ## Signal type and channel count This cable is rated for analog signal transmission only — the evidence explicitly states no digital signal transmission. That is a critical distinction: if you are wiring discrete 24 V DC sensors or actuators, this assembly is the wrong pick. It is designed for 4-20 mA, thermocouple, RTD, or voltage analog inputs that need the twisted-pair integrity of a pre-assembled round cable. The 40 poles match the 40-channel front connector on the S7-300 analog input module. Each pole carries one signal conductor; the cable bundles all 40 cores in a single sheath, keeping the wiring tidy and reducing the chance of a loose terminal in a high-vibration panel. ## Environmental limits and storage Storage temperature range is -30 to +70 °C; operating range is 0 to 60 °C. The PVC jacket is rated for indoor use in controlled environments — not for washdown zones or outdoor cabinets without additional protection.","metaTitle":"Siemens 6ES7922-3BD00-0BB0 Pre-assembled MTA Front Connector","metaDescription":"Pre-assembled front connector MTA for SIMATIC S7-300 PCS7. 40 poles, 3 m cable, screw-type enclosure terminal, 24 V rated, 30 V max.
