Technical Specification
Field Device Channels
| Specification | Details |
|---|---|
| Version Supported | HART Protocol v6 |
| Interface | 8 group-isolated channels |
| Communication to the Device | Point-to-point, master/slave, asynchronous, half-duplex, at 1200 baud |
| Error Checking | Parity on each byte, and one CRC check byte |
| Speed | 2 messages per second |
| Fastest Allowed ECB Block Period | 500 ms |
| Maximum Distance (FBM214 to Field Device) | Meets HART FSK physical layer specification HCF_SPEC-54, Revision 8.1 (up to 3030 m / 10000 ft) |
| Compliance Voltage | 18 V dc minimum at 20.5 mA |
| Current Inputs | |
| Sense Resistor | 61.9 Ω nominal |
| Total Input Resistance | 280 Ω minimum |
| Accuracy (Includes Nonlinearity) | ±0.03% of full scale |
| Temperature Coefficient | 50 ppm/ºC |
| Resolution | 15 bits |
| Update Rate | 100 ms |
| Integration Time | 500 ms |
| Common Mode Rejection | >100 dB at 50 or 60 Hz |
