Siemens V23030-A1026-A104 Axicom Signal Relay

The Siemens V23030-A1026-A104, also cataloged as the V23030-A1026-A104 Signal Relay, operates as a dedicated hardware component for low-power signal switching and galvanic isolation within industrial electronic control platforms. Utilizing a 48 VDC non-latching coil operating at 17.8 mA, this 14-pin card-style relay actuates a 4PDT (4 Form C) gold-overlaid silver alloy contact set. It routes low-level electrical signals across four independent channels while withstanding maximum switching limits of 250 VAC / 250 VDC at 2 A nominal contact current.

Hardware Specifications

Firmware Flash Compatibility

The Siemens V23030-A1026-A104 functions as a purely electromechanical hardware layer component, operating completely transparently to controller firmware flash updates and system software revisions. Because signal routing occurs through direct metallic bridge actuation via gold-overlaid contacts, the relay maintains microsecond-level response times independent of host PLC or DCS processor scan execution cycles. Backplane communication interfaces and digital logic cards interact with the device through standard 48 VDC driver outputs without requiring specialized hardware drivers or peripheral bus configuration licenses.

Frequently Asked Questions

Q: How does the 4PDT contact configuration execute signal paths on the V23030-A1026-A104?

A: The 4PDT (4 Form C) contact setup provides four mechanically linked changeover circuits, enabling simultaneous switching of four independent differential signal loops using a single 48 VDC coil activation signal.

Q: What physical limitations govern high-voltage and high-current power switching for this module?

A: Designed specifically for low-level signal conditioning, the gold-overlaid silver alloy contacts bear a nominal current rating of 2 A and a maximum switching threshold of 250 VAC / 250 VDC. Exceeding these thermal and dielectric thresholds will degrade contact plating and shorten mechanical operating life.

Q: What operational response timing does the non-latching 48 VDC coil deliver during state change?

A: The coil features a 2.7 kOhm resistance profile, achieving full contact set pull-in (operate time) within 8 ms of voltage application and open drop-out (release time) within 2 ms upon power removal.

Field Installation Guidelines

Position the 14-pin through-hole relay onto the printed circuit board, ensuring pin alignment conforms strictly to standard DIP footprint dimensions. Solder all terminals using controlled wave-soldering or manual thermal profiles to prevent localized heat transfer to internal armature springs and contact assemblies. Maintain adequate clearance from neighboring high-power transformers or high-frequency inductors to eliminate electromagnetic interference on sensitive signal paths. Inspect terminal connections and test coil resistance prior to applying continuous 48 VDC potential.
