1734-IE4C Allen Bradley POINT I/O 4 Point Analog Input Module

The Allen-Bradley 1734-IE4C module is a POINT I/O 4-channel high-density current input module. It is an analog module that can sustain channel-level diagnostics (electronic bits and LED indicators). It also features Delta-Sigma conversion of analog data to signed integer format, channel-level data alarming (4 set-points per channel); and scaling to different engineering units. This adapter supports the rack-optimized connections between CompactLogix controllers or ControlLogix and discrete I/O modules in the same chassis. via the backplane, it can also create direct connections between the internet-capable connection originator and input/output modules.

The 1734-IE4C analog input module has 4 inputs and a signed integer data format. It has an input signal range of 4 to 20 mA and 0 to 20 mA. Its input resolution is 16 bits at 0 to 21 mA, 0.32 microA/cnt. It has a maximum power dissipation of 0.6 Watts and a thermal dissipation of 2.0 BTU/hour, both at 28.8 Volts DC voltage. Its key switch position is 3, and the compatible thermal base units include the 1734-TOP, 1734-TOPS, 1734-TB, and the 1734-TBS. The 1734-IE4C is grounded via the DIN rail to chassis ground. To ensure proper grounding, use DIN rails that are zinc-plated yellow-chromate steel. Secure the DIN rail to the mounting surface approximately every 7.8 inches or 200 millimeters and use the end-anchors correctly. The installation of the 1734-IE4C module can be done before or after the base is secured. The insertion or removal of the module should be done while backplane power is switched off to avoid the occurrence of electrical arcs.
