Reliance AutoMax PLC Controller 0-57C421B Drive Module
The 57C421 is a Pulse Tach input module originally designed by Reliance Electric.
Depending on its year of manufacture, it is likely that this module was also sold by Asea Brown Boveri or Baldor Reliance.
Neither of these original manufacturers no longer maintain this part and it has become difficult to locate.
Reliance Electric uses the 57C421 as an important part of the AutoMax Multibus I/O system.
This module uses eight resistors to perform various AutoMax programming tasks. These resistors are capable of reading from or writing to programming tasks.
The board does not come with on-board jumpers. The module has an input voltage of 5 volts to 12 volts DC. It has a maximum frequency input of 100 kHz.
It has 500 volts RMS isolation. It has a 24-bit comparator and counter. The system also has 3 channels of input pulses, A-phase, B-phase, and Z-pulse. These pulses can be used to track the zero position.
The 57C421 has a set of LEDs labelled COUNT STOP, LATCH, CLEAR, FORWARD, REVERSE and CCLK OK.
These LEDs monitor generated interrupts. There is a row of 20 female connection ports. Two dials are labelled.
One is labelled A, B, C, D, E, F, and G and the other is numerically labelled with numbers 1-7.
