Description

3700A

Tricon
TMR Analog Input Module

Triconex 3700A acquires differential analog signals for a Tricon controller. It provides thirty-two DC-coupled input points with a five-volt range and overrange allowance. Independent conversion paths deliver measured data to the main processors. Mid-value selection supports the triplicated input architecture. Continuous channel diagnostics identify faults through the module and chassis indications. A separate external termination panel provides the field-wiring interface.

04

Working Principle

Independent input conversion

Three input paths acquire and convert the connected analog signal for processor use.

Mid-value selection

The Tricon input architecture selects the middle value from the triplicated measurements.

05

Product Applications

Differential voltage acquisition
Measure suitable process-instrument voltage signals within the common-mode and input range limits.
Current-loop termination
Use the specified external shunt arrangement when converting transmitter current into the voltage-input range.

Transaction Cases

Sincere Cooperation, Long-Term Trust
Germany

A Germany customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.

India

An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.

Malaysia

A Malaysia customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
