TRICONEX 3502E TMR Digital Input Module 48VAC/NDC
Part number: 3502E
Manufacturer:Triconex
Product Description: TMR Digital Input Module
Specifications for 3502B TMR Digital Input Module, 48VAC/VDC:
Color code:dark red;Input points:32, shared within 8 groups;Recommended input range:35-95VAC/VDC;Maximum voltage:95VAC/VDC
Models 3502E, 3503E, and 3505E include a self-test feature which verifies the ability of theTricon controller to detect transitions from a normally energized circuit to the Off state. Because most safety systems use a de-energize-to-trip setting, the ability to detect the Off state is an important feature. To test for stuck-On inputs, a switch within the input circuitry is closed to allow a zero input (Off) to be read by the optical isolation circuitry. The last data reading is frozen in the I/O Processor while the test is running.
