10-pin terminal connector "screw - type" - power, relays, RS-485
Pins assignment (from left to right):
- 1. Common24V
- 2. "+" line of 24В
- 3. Isolated gnd for LAN/WAN cable shields
- 4. Relay #1 N.O.
- 5. Common wire for relays #1,2
- 6. Relay #2 N.O.
- 7. N.C.
- 8 RS-485 signal ground
- 9 Data- (:B) RS-485
- 10 Data+ (:A) RS-485
- Connection of RS-485 - refer to this.
- Switching capacity for SSRs - max. current 100мА ~/=, max. voltage - up to 350V.
- When using shielded Ethernet cable its shield will connect to GND terminal, which in his turn recommended to wire to ground for better noise protection.
- Voltage input 24В +/- 10% (15%).
Разъем подключения внешней антенны WiFi (тип RP-SMA)
