4-7 PLC Controller

The PLC controller uses an Allen-Bradley programmable logic controller (PLC). This “brick”- type controller has 32 I/O points: twenty (20) inputs and twelve (12) outputs, all inputs and outputs are 115 VAC.

All programming and logic is factory-installed on an EEPROM chip and cannot be modified. A battery backup retains programming if power fails. Battery life is five (5) years at room temperature.

If the alarm indicator blinks intermittently, replace the battery within one week.
