7. CONNECTOR WIRING INFORMATION

CONNECTORS

Connectors for signal and power are UL-rated

screw-clamp terminal blocks that plug into

mating jacks on the printed circuit board.

Communication connectors are a single RJ11

plug for RS232, dual RJ11 plugs for RS485,

dual RJ45 plugs for RS485 Modbus, or USB.

Warning: Hazardous voltages may be present on pins 4, 5 & 6 of P1 since digital ground is

tied to pin 3 of P5 (-Signal Input). Keep pin 3 close to earth ground to minimize common mode

voltage or shock hazard at pins 4, 5 & 6 of P1.

P4 – SIGNAL INPUT

Excitation voltage can be jumpered for 5, 10 or 24 Vdc (Section 17).

* Control inputs 1 & 2 of P1 are menu

selectable.
