The B884-002 PID module provides two completely independent and separate Proportional Integral Derivative (PID) loops. You can configure the PID loops for control strategies including open loop, closed loop, PID, PID on error squared and cascade control.

You configure the PID module using a configuration program (Part #SW-BDD-3DA) on an IBM or compatible personal computer. You can download the data either through the PLC or directly to the modules, where it is stored in a non-volatile EEPROM memory.

To ensure the highest accuracy and reliability, the module has fully floating, isolated and protected inputs and outputs. The module has seven independently configured analog inputs (4 voltage/current, 2 thermocouple, 1 frequency), two analog outputs, two discrete inputs and two discrete outputs. Each loop is assigned two voltage and one thermocouple inputs.

There is no need for any analog adjustments such as trimpots for zero, offset, or span, which results in superior accuracy, stability and reliability.
