DOM-PV module

DOM-PV module is designed to handle up to 8 digital outputs related to actuators of the PV system (remote resetting
of breakers, on / off remote control of devices, etc …), on command sent by the E2M-PV via ModBus on RS485 line.

The normal-status of each digital output can be configured independently of the others; commands sent by the E2M specify
the monostable or bistable mode: in the first case, the output will remain in the active state for 5 seconds, then it will return to its normal status; in the second case, the output will remain in active state until next command.

DOM-PV module is equipped with 2 LEDs:

• green LED is lit with high blink (2 Hz, 50% duty cycle) to indicate the absence of interrogation by the master, and with slow blink (200 ms every 4 seconds) in case of regular communication (reception of a correct message in the last 30 seconds);
• red LED is used to signal fails (eg, reception with errors) and is automatically reset at the absence of the error condition.

• 8 open-collector digital ouputs 30 Vdc – 10 mA
• RS485 serial line (3 wires)
• 2 signaling LEDs:
• green for power / data link status
• red for alarm
• 12 Vdc power supply directly from the E2M-PV-module
• 2.5 kV insulation between power supply and digital ouput channels
• Connections:
• nr. 2 8-pin terminal blocks for digital ouputs
• nr. 1 10-pin terminal block for power / data cable incoming and outgoing:
  (3-pin for RS485 + 2-pin for power) x 2, for input and output to the next node
• Protocol: ModBus RTU, addressing by 4 dip-switches
• Enclosure: vertical DIN rail, IP30 degree of protection
