TRICONEX  3721 TRICON Analog Input Module (TMR）

Part number: 3721

Manufacturer:TRICONEX

Product Description:Analog Input Module

The TRICON 3721 has 32 differential DC-coupled input points and accepts voltage inputs in the 0 to 5 VDC or -5 to +5 VDC1, +6% range. The TRICON 3721 has an accuracy of less than 0.15% of full scale range (FSR) over the 0° to 60° C range and has -85 dB (DC - 100 Hz) common-mode rejection.

The TRICON 3721 is used as an analog input module in safety instrumented systems (SIS) and ESD systems. three channels in the TRICON 3721 measure input signals asynchronously and place the results in a value table. Each of the three input tables is passed to its associated master using the corresponding I/O bus.

Typically, the CPU is the heart of a programmable logic controller (PLC) such as the Tricon control system. the TRICON 3721 analog input module is designed to be used with the CPU and its configuration may vary. the CPU in a PLC can be a general purpose microprocessor, a microcontroller microprocessor, or a bit chip microprocessor. The CPUs in small PLCs are mostly 8-bit general-purpose microprocessors or microcontrollers, while medium-sized PLCs usually use 16-bit general-purpose microprocessors or microcontrollers. Large PLCs usually use high-speed bitchip microprocessors.
