<< | < | AX-FRM3+1-TX - Fan Speed 3+1 Relay Module with Transformer
|
| |
|
|
The AX-FRM3+1-TX range incorporates three interlocked relays, an additional independent relay, and a transformer in either a DIN rail mounting or an IP55 enclosure. It is intended for use with 24Vac powered thermostats to provide interlocked fan speed switching with an additional auxiliary output to switch a cooling valve. The unit can be used to change fan speeds on fan motors with multi-tapped windings and also transformer speed controlled motors. The 'break before make' design of the relay contact configuration and common switching point ensure that only one set of contacts is active at any one time, thus preventing short circuits. The three fan relays are powered by the transformer and switched with volt-free contacts. Two pairs of 24Vac outputs are also provided. |
