Tips for Using Modular Terminals
The Biomet station includes DIN-rail mounted modular terminals to provide electrical connections for sensors, switches, and resistors. Two types of modular terminals are included: 2-position terminals that have two electrically connected terminals, and 4-position terminals that have 4 electrically connected terminals. Red terminals are power (+), blue are ground (-), and gray are signal or auxiliary. The modular terminals can accommodate wires from 26 AWG to 14 AWG.
Terminals for Incoming Power
| DIN terminal | Assignment | Notes |
|---|---|---|
| 1, 2, 3 | System power (+) | Power in terminals; electrically connected |
| 4 | System ground | System ground terminal |
| 5, 6, 7 | System power (-) | Power in terminals; electrically connected |
Terminals for Sensors and Components
| DIN terminal | Assignment | Notes |
|---|---|---|
| 8 | Power (-) | Power to instruments |
| 9, 10, 11 | Power (+) | 24 or 12 VDC power to instruments |
| 12, 13, 14 | Power (+) | 12 VDC power to ancillary devices |
| 15 | SDI-12 ground | Used with Stevens Hydra Probe II |
| 16 | SDI-12 power | Used with Stevens Hydra Probe II |
| 17 | SDI-12 signal | Used with Stevens Hydra Probe II |
| 18, 19, 20 | Power (-) | Power for datalogger, relay, and CNF4 |
| 21, 22, 23 | Power (+) | 12 VDC power for datalogger, relay, and CNF4 |
