First select the type and then the device variant (item no.) using the function modules.
Type selection
| Type | Display | IOs; relays (change over contact) | Supply voltage | Housing |
|---|---|---|---|---|
| RCMS410 | LED bargraph | M+, Q, I | DC 24 V | 1 DU |
| RCMS425-L | LED bargraph | M+, Q, I; K1, K2 | DC 24 V; AC/DC 100...240 V | 2 DU |
| RCMS425-D | TFT display | M+, Q, I; K1, K2 | DC 24 V; AC/DC 100...240 V | 2 DU |
Functional Module Selection
The function modules can be purchased ex works or subsequently as an unlimited licence. Subsequent activation of individual or multiple function modules is possible for all variants (item no.).
All variants can be used with type A/F measuring current transformer series.
The B function module is required to use type B/B+ measuring current transformer series for AC/DC sensitive measurement.
Function modules:

* As part of the ordering process, customer-specific factory settings can be defined together with our sales department for some parameters (e.g. response values and interface settings) with which the units are delivered. The reference to a customer-specific configured variant can then be found on the packaging of the individual product as well as in the delivery note (the changed parameters are listed there, the assignment is made via the item number in the delivery note and the serial number of the unit).
