A PC (Programmable Controller) is basically a CPU (Central Processing Unit) containing a program and connected to input and output (I/O) devices.

These spacers are used to take up space in the I/O chasis.

24-VDC inputs; w/high-speed input; 0.1-A, 4-VDC outputs (useable as 128-point dynamic input unit) 16 input and 16 output pts

A device connected to the PC that sends a signal to the PC is called an input device; the signal it sends is called an input signal.

A device connected to the PC that sends a signal to the PC is called an input device; the signal it sends is called an input signal.

Technical Specifications: 16 mA at 4.5 V to 100 mA at 26.4 V

A total of eight I/O Units mounted to the Backplane. When using 16-point Output Units (models C200H-OC225/OD212/OD21A) mount them to a C200H-BC 1-V1/V2 Backplane.

The ASCII/BASIC module provides a 24-Kbyte programmable coprocessor module that operates independently of the PLC.

These C200H Backplanes are used for CPU racks, local, and remote expansion racks. Tey are available with 3,5,8, and 10 I/O slots.
