Siemens 6RA8222-8CA0 frequency-to-voltage converter module. Manufacturer: Siemens. Part Number: 6RA8222-8CA0. Product Type: plug-in signal conversion module. Function: converts an input frequency into a proportional analogue voltage. Product Family: Simoreg U308 signal modules. Drive Platform: Simoreg DC drive systems. Manufacturer Status: discontinued.
6RA — the Siemens order-number group for Simoreg DC converter and drive equipment.
8222 — the plug-in signal-module family within that group, the U308 type.
Function: frequency-to-voltage conversion. The module takes a pulse train — typically from a tachometer, a pulse encoder or a proximity pickup on a rotating shaft — and produces a DC voltage proportional to its frequency. That is what turns a digital speed signal into the analogue feedback or setpoint a DC drive regulator works with.
Product Family: Simoreg U308. The same module type is used as a frequency monitor, where the converted voltage is compared against a threshold to signal overspeed, underspeed or a stalled shaft.
Drive Platform: Simoreg DC drive systems. Simoreg equipment supplies armature and field current to DC variable-speed motors from a three-phase line, and the plug-in modules add the measuring and monitoring functions around it.
Mounting Type: plug-in module, seated in the drive’s module rack.
Mounting Type: plug-in module in a Simoreg module rack.
Unit Quantity: 1 Pc. The listing is for one module.
MPN Variants: 6RA8222-8CA0, 6RA82228CA0, 6RA8222 8CA0.
Related order numbers in the same block include 6RA8222-8CA1 and 6RA8222-8PA0. The trailing execution code carries the function and the range, so match on the full order number.
