The 57C401 is a drive I/O module created to go with the AutoMax programmable logic controllers. This module weighs 2 lbs.
The 57C401 has a lot of features on its faceplate. It has 20 rectangular I/O connection ports labeled A1, A2, B1, B2, C1, C2, D1, D2, E1, E2, F1, F2, G1, G2, H1, H2, H3, I1, I2, and I3. There is a set of 12 LED indicator lights that are labeled A-I. These LEDs are also labeled net, aux 1, aux 2, M status, run, run perm, DFR, FMCR, RMCR, and MCR. These LEDs will glow when the status quo of these inputs is disrupted so that the user will know to check the corresponding I/O connection. There are two dials or key slots that are on the faceplate. One is labeled B, C, D, E, F, and G while the other is labeled numerically 1-3 on the left side and 6-8 on the right.
