GE Mark VI IS220PAICH1A 336A4940CSP3 Analog I/o Module

The IS220PAICH1A is an analogue I/O Pack developed under the GE Mark VI family. simplex and triple modular redundancy (TMR) Mark VI control systems can be used in both small applications and large integrated systems, with control ranging from a single module to multiple distributed modules. The system's throughput allows operation of up to nine I/O boards in a 21-slot VME rack in 40 milliseconds, including data polling. In a method known as Software Implemented Fault Tolerance, inputs are polled in software (SIFT). Each control module's VCMI board takes inputs from the control module backplane and other modules through its own IONet.

The IS220PAICH1A model is described as an analogue I/O package, approved for use in hazardous and non-hazardous locations. There are four indicator lights on the front of the model. There is also a port on the bottom called the I/O port.The PAIC pack can be used with a wide range of voltages and the minimum voltage for the PAIC pack is twenty-seven point four volts DC.

Because the IS220PAICH1A package can be used in a variety of locations, there are a number of approvals associated with it, some of which are Hazardous Locations, Class I Zone II Group IIC, Class I Division II Groups A, B, C, and D, as well as ATEX Zone 2, IIC Groups, and Non-Hazardous Locations. The following certifications are for these locations: UL E207685 and UL DEMKO 12 ATEX 1114875X, please consider that UL E207685 is certified for many locations.

The IS220PAICH1A unit is available in three models, the IS200STAIH1A and IS200STAIH2A and the IS20TBAIH1C models. All of these models are referred to as input and output terminal blocks.
