IC655MDL576 is a programmable Series Five I/O module that builds on the latest modern technology. Each one of the series five modules requires a Storage Temperature 0 to 60°C (32 to 140°F) (at outside of rack, no fans or Forced air), environment 5% to 95% (non-condensing) no corrosive gases and Dielectric withstand Insulation Resistance1500 VAC. The power consumption load is located on the internal +5 VDC power. It is serviced by the power supply set up at the base unit where modules are located. For example, CPU, Communications Control, or any other smart modules are used, to sum the whole amount of load.

The I/O modules have some attributes that consist of discrete input and output, which is of high density, analog input and output and an ASCII/BASIC Module. These I/O modules are similar in size and are placed in a plastic module environment. The series Five I/O modules join the backplane via one connector found on the module. The series five I/O modules do not need any equipment for installation.

In terms of Module Keying, every 16 and 32 parts of Series Five I/O modules are inserted to avoid any connection that could be connected accidentally to the unintended module type. There is a set of guidelines that should be followed while setting up the keys. This key consists of two types: modules with 20 terminals and modules with 38 terminals both found on the terminal block. The I/O Module Specs consist of CPU that acts as a Diagnostic Keying Check that is used to ensure that the latest laid module is placed on the right port to facilitating good operational processes.

There is also a Terminal Block for Field Wiring (16 and 32 Point Modules) that permits accessibility to a terminal block that allows linking up of field wiring. Series Five I/O modules installations can be done on I/O slot in a base unit which is present. Those Base units may have 6 (IC6SSCHS506) or 8 (IC655CHS508) I/O modules. All I/O modules have rules during installation for example, do not place or remove the /O module when there is power at the base unit to avoid spoiling the module. To link up to user input devices, the series five I/O modules offers almost 32 input circuits. These circuits are in four categories each consisting of 8 circuits. 12 to 24 VDC source of power to detect the condition of the inputs to the modules.

I/O module which has a switching capacity of 0.5 amps and offers 32 circuits that can be used to control user output loads. Also, it has 64 circuits that connect to user input devices.  Series Five 8 channel has an analog input module that produces eight input channels, every one of these eight channels have the capacity to change analog signals 12 bits binary (1 part in 4096) to digital signals necessary to run applications. The inputs are of +1 to +5 V, 0 to +1O V, -10 to +1O V, or 4 to 20.
