Siemens V23012-A0133-B001 Axicom Signal Relay
Configured for low-power signal switching in industrial control platforms, the Siemens V23012-A0133-B001 (V23012-A0133-B001 Signal Relay) provides direct physical contact actuation with galvanic isolation on printed circuit boards. Operating on a 48 VDC nominal coil drive with an 82 Ohm coil resistance, this DIP-9 through-hole card relay utilizes a DPDT (2CO / 2 Form C) contact structure. The bifurcated silver contacts feature gold flashing to route low-level electrical signals, supporting switching rates up to 50 operations per second across a maximum voltage threshold of 250 VAC / 250 VDC at 2 A nominal contact current.

Firmware Flash Compatibility
The Siemens V23012-A0133-B001 operates as a passive electromechanical relay component, remaining completely isolated from host PLC or DCS firmware flash updates and operating system revisions. Because contact state changes rely on magnetic flux generation within the 82 Ohm DC coil rather than digital bus protocols, the device executes millisecond-level signal paths without requiring communication licenses or backplane drivers. Hardware logic controllers interface directly through standard 48 VDC transistor or relay driver outputs, ensuring signal continuity across system firmware migrations.
Frequently Asked Questions
Q: How do the bifurcated gold-flashed contacts enhance performance on the V23012-A0133-B001?
A: Bifurcated (double) contacts provide parallel electrical connection paths for each pole, while gold flashing prevents contact oxidation. This arrangement lowers contact resistance and prevents signal dropouts during low-voltage, low-current switching operations.
Q: What power drive parameters apply to the 48 VDC coil configuration?
A: The coil features an approximate DC resistance of 82 Ohm, requiring roughly 250 mW pick-up power to actuate the armature and consuming 450 mW under nominal 48 VDC continuous operation at 20 deg C.
Q: Can this signal relay drive inductive AC power loads or heavy motor circuits?
A: No, this module is rated for control and measurement circuit switching up to 2 A. Connecting inductive power loads exceeding its rated contact capacity will cause contact arc degradation and premature failure.
Field Installation Guidelines
Position the DIP-9 package onto the target printed circuit board, aligning all through-hole pins with designated PCB pads. Apply controlled soldering thermal profiles to prevent excessive heat conduction into the dust-protected enclosure and internal spring mechanisms. Maintain adequate trace spacing between 48 VDC coil drive conductors and analog signal paths to suppress cross-talk and inductive noise coupling. Inspect solder joints and verify coil resistance prior to applying system operating power.
