At a Glance
| Brand | Siemens |
|---|---|
| Model | 6ES7492-1AL00-0AA0 |
| Product Type | Front connector |
| Core Function | Removable signal-module field wiring |
| Application | SIMATIC S7-400 signal modules |
Screw-contact termination
Field wiring is secured at the front connector rather than directly on the module body.
Prepared-wire options
Bare flexible conductors and suitable ferruled conductors have distinct cross-section limits.
Module service access
The wired front connector can be prepared separately and removed during module replacement.
Product Overview
6ES7492-1AL00-0AA0 provides the detachable screw-terminal field interface for compatible SIMATIC S7-400 signal modules.
The connector carries the module-specific channel wiring, with conductor preparation, terminal torque and the installed module pin assignment determining the installation.
Key Functions
Connect the signal-module field circuits
The 48-pole front connector accepts the channel wiring assigned by the selected S7-400 signal module.
Prepare wiring outside the module
Conductors can be terminated on the prepared front connector before the connector is installed on the module.
Retain field connections during servicing
The removable front wiring interface supports signal-module exchange without reterminating each field wire.

Frequently Asked Questions
What wire cross-section can I use without ferrules on 6ES7492-1AL00-0AA0?
Bare flexible conductors may have cross-sections from 0.25 to 2.5 mm².
Can I fit a 2.5 mm² ferruled conductor into 6ES7492-1AL00-0AA0?
No, the permitted range for flexible conductors with ferrules is 0.25–1.5 mm².
How tightly should the screw contacts of 6ES7492-1AL00-0AA0 be fastened?
Tighten each terminal screw to 0.6–0.8 N·m, including terminals that are not wired.
How much insulation should I remove when wiring 6ES7492-1AL00-0AA0 without ferrules?
Strip 8–10 mm of insulation from the conductor before termination.
Can two 1.0 mm² wires share a terminal on 6ES7492-1AL00-0AA0?
Yes, a combination of two 1.0 mm² conductors is permitted when an appropriate special twin ferrule is used.
Where should I begin when terminating a prepared 6ES7492-1AL00-0AA0?
Begin wiring at the bottom of the front connector and work through the remaining connections.
Does 6ES7492-1AL00-0AA0 determine the channel assignment of an S7-400 module?
No, the installed signal-module type determines the function and wiring assignment of the connector contacts.
