Overview
The 6AG1134-6PA01-7BU0 is a Siemens SIPLUS ET 200SP analog input module, specifically the AI Energy Meter CT ST variant, designed for extreme-condition environments with conformal coating and a -40 to 70 °C operating range. Based on the standard 6ES7134-6PA01-0BU0, this SIPLUS version accepts inputs from 1A or 5A current transformers and mounts on a BU type U0 base unit, making it suitable for energy monitoring in cold or hot industrial enclosures.
Function & operation
This module reads current transformer signals for energy metering — it accepts either 1A or 5A CT secondaries, which covers the two standard industrial CT output ratings. The channel diagnostics flag open-circuit or overload conditions on the CT loop, useful for fault isolation on a live panel. The conformal coating protects the board against condensation and corrosive atmospheres, which is the key differentiator from the standard ET 200SP variant. The -40 to 70 °C range means it can sit in an unheated cabinet in a cold climate or near a hot process line without derating.
Applications
This module fits into SIPLUS ET 200SP distributed I/O systems deployed in extreme environments — cold storage warehouses, outdoor material-handling yards, food-processing areas with washdown, and chemical plants where standard electronics would fail from condensation or temperature cycling. The energy meter function makes it a natural choice for submetering motor control centers or production line power monitoring, where the CT inputs connect directly to existing 1A or 5A current transformers without an external signal conditioner.
Market & positioning
Within the Siemens SIPLUS ET 200SP range, the 6AG1134-6PA01-7BU0 is the conformal-coated, wide-temperature version of the standard AI Energy Meter CT ST (6ES7134-6PA01-0BU0). It targets OEMs and integrators who need the same energy-monitoring function but must guarantee operation in environments where standard IP20 modules would see condensation or temperature extremes.
Lifecycle & availability
The 6AG1134-6PA01-7BU0 carries an active lifecycle status, meaning Siemens continues to manufacture and support it. No last-time-buy or phase-out notice is in effect, so it can be sourced through standard distribution channels without urgency.
Compliance
RoHS compliance is documented with a status date of 13-09-24, confirming the module meets the Restriction of Hazardous Substances directive as of that date.
