3.8 Optically Isolated Inputs
Models equipped with inputs contain up to two optically isolated inputs, IN1 and
IN2. These inputs must be wetted from an external power supply between 38 and
160 VDC or 38 to 120VAC. Connections are made through plug-in terminal
blocks on the rear of the case as shown in figures 3.18a & b.. These optically
isolated inputs may be used by the programmable logic to control or supervise
any output. These inputs can also be used to communicate status information
from devices such as the liquid level alarm or sudden pressure over DNP3.0 or
MODBUS. Any input can be programmed to be LEVEL or PULSE active. The
use of shielded cable is recommended.
