RIGEL2-MT-RS485 datasheet
Specifications, wiring and ordering information for the RIGEL2-MT-RS485.
Specifications for the RIGEL2-MT-RS485. What it is for and its key features are on its product page.
Temperature measurement
| Parameter | Value |
|---|---|
| Output signal | RS485 Modbus RTU |
| Temperature sensing range | −40 °C to +150 °C |
| Accuracy | IEC 60751 Class A, ±(0.15 + 0.002|t|) °C ¹ |
| Uncertainty | ±0.3 °C |
| Resolution | 0.01 °C |
| Sensor element | RTD PT1000 Class A |
¹ |t| is the temperature in °C, ignoring its sign.
Electrical
| Parameter | Value |
|---|---|
| Supply voltage | 12 VDC / 24 VDC (power input rated +9 to +28 VDC) |
Physical and environmental
| Parameter | Value |
|---|---|
| Operating temperature | −40 °C to +80 °C (electronics) |
| Ingress protection | IP65 |
| Material, sensing disc | Aluminium 6082, anodised |
| Material, electronics housing | ABS |
| Sensing disc size | Ø 25.4 mm × 7.2 mm |
| Weight | <20 g (excluding cable) |
| Cable | Li2YD11Y, 24 AWG, braided shield, extruded polyurethane insulation |
The sensing disc reads up to +150 °C, but the electronics housing is rated to +80 °C, so mount the housing out of direct contact with the module.
Wiring
| Wire colour | Function |
|---|---|
| Red | Power input, +9 to +28 VDC |
| Grey | Power ground |
| Yellow | RS485 + (A) |
| Blue | RS485 − (B) |
| Green | Chassis ground (earth) |
| White | Reserved, leave unconnected |
| Pink | Reserved, leave unconnected |
| Brown | Reserved, leave unconnected |
Connect the yellow and blue pair to the logger's RS485 port, terminate the bus at both ends as usual for RS485, and earth the green wire at one point only.
