Signal Isolations

• PV input terminals: Isolated from other input/output terminals. Not isolated from the

internal circuit.

• Remote input terminals: Isolated from other input/output terminals and the internal

circuit.

• 15 V DC loop power supply terminals: Not isolated from analog current output and

voltage pulse control output. Isolated from other input/output terminals and internal

circuit.

• Analog output terminals (for control output and retransmission): Not isolated between

analog outputs and from 15 V DC loop power supply and voltage pulse control output.

Isolated from other input/output terminals and internal circuit.

• Voltage pulse control output terminals: Not isolated from analog outputs and 15 V DC

loop power supply. Isolated from other input/output terminals and internal circuit.

• Relay contact control output terminals: Isolated between contact output terminals and

from other input/output terminals and internal circuit.

• Contact input terminals: Not isolated between contact input terminals and from com-

munication terminals. Isolated from other input/output terminals and internal circuit.

• Relay contact output terminals: Not isolated between relay contact outputs. Isolated

from other input/output terminals and internal circuit.

• Transistor contact output terminals: Not isolated between transistor contact outputs.

Isolated from other input/output terminals and internal circuit.

• RS-485 communication terminals: Not isolated from contact input terminals. Isolated

from other input/output terminals and internal circuit.

• Feedback slide resistance input terminals: Not isolated from analog output terminals

(control, retransmission), 15 V DC loop power supply, and voltage pulse control

outputs. Isolated from other input/output terminals and internal circuit.

• Power terminals: Isolated from other input/output terminals and internal circuit.

• Grounding terminals: Isolated from other input/output terminals and internal circuit.
