The Triconex 3501T is a 32-point, non-commoned, isolated digital input module for use with Triconex safety PLCs. It is designed for use in hazardous areas and has a wide operating voltage range of 90 to 155 VAC/VDC. The 3501T has a switching level of >86 VAC/VDC for off to on and <28 VAC/VDC for on to off. It also has a nominal turn-on current of 6-9 mA and a typical hysteresis of 32 VAC/VDC. The input delay is <8 ms for off to on and <15 ms for on to off. Each point on the 3501T is isolated from the others and from the module ground, providing a maximum point isolation of 1,500 VDC/2500 VDC. The module has a nominal input impedance of >8.5 KΩ and a nominal field power load of 1.5 watts per on point.
The 3501T has a number of diagnostic features, including input status indicators for each point and module status indicators for PASS, FAULT, and ACTIVE. The module also has a watchdog timer that can be used to detect and recover from communication errors.
The 3501T is a versatile and reliable digital input module that is well-suited for use in a variety of industrial applications. It is especially well-suited for use in hazardous areas where its isolation and diagnostic features provide added safety.
