Product details

Dual AS-i Address — The Integration Constraint

The 3RK1408-8SQ00-0AA3: This module occupies two addresses on the AS-i network — one for the four inputs and one for the four virtual outputs. That means the master must have two free slots in its address table, and the module's I/O configuration code is 7. The 4 inputs are PNP transistor type, and the 4 outputs are virtual — they exist as AS-i data points without physical relay or transistor drivers on the module. Yellow LEDs show I/O status; a green/red LED indicates AS-i communication and diagnostics.

IP67 Machine-Mount Deployment

Rated IP67, this K60 compact module mounts directly on machine frames via standard rail or wall mounting using the separately ordered mounting plate 3RK1901-0CA00. The 60 mm width and 29 mm depth fit tight panel layouts. Operating temperature range is -25 to +85 °C, with storage from -40 to +85 °C. Shock resistance is 15 g for 11 ms — suitable for vibrating conveyor or packaging machinery.

Bus-Powered, No External Supply Needed

The module draws its operating power entirely from the AS-i bus cable — 70 mA max at 26.5-31.6 V per the AS-i specification. No external 24 V DC supply is required for the outputs, which simplifies the wiring harness to a single AS-i flat cable. All eight sockets on the module are closed (not assigned), and a watchdog is not required. The front addressing socket allows ID/ID2 code setting to F/F.

Frequently asked questions

What does 'the module requires an address in each of the two AS-i networks' mean?

This AS-i data coupler occupies two AS-i addresses — one for the 4 digital inputs and one for the 4 virtual outputs. The master must have two consecutive free addresses available, and the module's I/O configuration code is 7.

What is the I/O configuration of 3RK1408-8SQ00-0AA3?

It provides 4 digital inputs (PNP transistor type) and 4 digital outputs (virtual). The outputs exist as AS-i data points without physical switching elements on the module.

Will 3RK1408-8SQ00-0AA3 drop into a panel specified around 6ED1052-1MD08-0BA1?

No — the 6ED1052-1MD08-0BA1 is a LOGO! expansion module with a different form factor, bus interface, and mounting system. The 3RK1408-8SQ00-0AA3 is an AS-i bus slave on the K60 platform; rewiring and a different master interface would be required.
