About PLC-5-20C

The Allen-Bradley PLC-5-20C is a PLC 5 1785-L20C ControlNet PLC-5 Processor. The weight of the PLC-5-20C is around 3 lbs, 3 oz (1.45 kg). The keying positions of this module are between pins 40 and 42 and also between pins 54 and 56. The maximum user memory words of this module are 16 K. The Program Scan Times of this module is 0.5 ms per K word (bit logic) and 2 ms per K word (typical). The transmission rate of ControlNet is 5 M bit/s.

The Allen-Bradley PLC-5-20C uses the 1770-XYC battery. The memory modules that support the PLC-5-20C are the 1785-ME16, 1785-ME32, 1785-ME64, and the 1785-M100. This module comes with a DH+ and Remote I/O port. The backplane current (3A at 5V DC) of this module is 2.7A. The heat dissipation of this module is 54 BTU/hr. The operating temperature of the PLC-5-20C is 0-60 °C (32-140 °F), the storage temperature is -40-85 °C (-40-185 °F), and the relative humidity is from 5-95% without condensation. The Allen-Bradley PLC-5-20C has an operating shock of 30 g peak acceleration for 11+1 ms duration. The nonoperating shock is 50 g peak acceleration of 11+1 ms duration. The vibration of this module is 1 g at 10-500 Hz (0.012 inches peak to peak displacement). The PLC-5-20C module is shipped in a static-shielded container to prevent electrostatic damage. This electrostatic discharge may damage the integrated circuit or semiconductor in the PLC-5-20C processor module if you touch the backplane connector pin and create a static charge.
