Product Description

The SCH-2 interface module is a versatile SCH-2 I/O converter and SCH-2 signal conditioner designed for industrial automation, energy management, and process control applications. It features two configurable inputs and two isolated outputs, supporting direct integration with up to two peripheral modules. Operating within a 12-24V DC voltage range and -20°C to 60°C temperature tolerance, it ensures reliable performance in harsh environments. Equipped with RS-485 communication, the SCH-2 enables seamless data exchange in networked systems. Its compact design and high-precision signal conditioning (0-10V/4-20mA compatibility) simplify installation and reduce calibration needs. While lacking onboard battery or display, it excels in robust signal conversion with a 10-meter maximum sensor detection range, though its fixed I/O count limits scalability for large-scale expansions.
