The PLC 1785-ME32 is a PLC 5 Memory Device Module. The operating temperature of this module is 0-60 °C (32-140 °F). The storage temperature of this module is -40-85 °C (-40-185 °F). The relative humidity of this module is from 5-95% without condensation. The Backplane Current of this module is 2.5 A at 5V DC. The maximum number analog I/O of this module is 3072. The Maximum I/O Chassis Universal Remote of this module is 32 per I/O Link. The PLC 1785-ME32 has memory size of 32K. The 1785-ME32 can be used as a Backup Program. This module has an operating shock of 30g (3 pulses, 11 ms). The nonoperating shock of this module is 50g (3 pulses, 11 ms). This module comes with a Control Coprocessor Expansion Port. This module has an ESD immunity of 6 kV contact discharges and 8 kV air discharges. This module has a Radiated RF immunity of 10 V/m with 1 kHz sine-wave 80% AM from 30-2000 MHz and 1 V/m with 1 kHz sine wave 80% AM from 2000-2700 MHz.
The 1785-ME32 module is a user-modifiable read-only memory (ROM) module which is erasable and it can be reprogrammed repeatedly through applications with a higher than normal power supply voltage. This module is used to store a small amount of data that must be stored when power is removed as in the calibration table or device configuration. Turn off all the power to the chassis and I/O processor before downloading the program from this module.
