About the 4090-5206
MX Technology module that watches the MX Loop for short circuits and connects or isolates the wiring with solid state switches. A fault on the input or output side opens that switch, so a Class A loop keeps working and the shorted section is cut off. A spur circuit can be connected between the input and output switches.
A fault on the spur circuit opens both switches and separates the spur from the rest of the loop.
Specifications
| MX Loop current | 0.08 mA in standby; 6 mA with single trip; 10 mA with double trip (fault on spur circuit) |
|---|---|
| Switching | Solid state switches on the input (left side) and output (right side) |
| Mounting box | Standard 2-gang MK box |
| Wiring connections | Terminal blocks, for wire size 20 to 14 AWG (0.5 to 2.5 mm²) |
| Operating temperature | 32° F to 120° F (0° C to 49° C) |
| Humidity | up to 93% RH at 90° F (32° C) |
