Active production, 15 mm wide thermocouple input
The Siemens 6ES7134-4NB00-0AB0 is an ET 200SP analog input module that fits two thermocouple or ±80 mV voltage channels into a 15 mm wide slice. The module is powered from the backplane at 24 V DC and draws a typical 0.6 W, so there is no separate supply wiring.
Panel fit and wiring
Depth is 52 mm, height 81 mm — it sits in the ET 200SP base unit's standard slot without protruding into the wiring duct. Isolation between channels and backplane is tested at 500 V DC, which covers the common-mode voltages seen in industrial thermocouple runs. Shielded cable runs up to 50 m are supported; the module is parameterizable to enable or disable wire-break diagnostics and group error reporting.
Configurable diagnostics and integration time
Integration times of 16,7 ms and 20 ms are available. Group diagnostics can be enabled or disabled, as can overflow/underflow alarms. Between-channel isolation is not provided, so the module relies on the base unit's isolation.
