Johnson Controls C450SQN-4 2-Port Isolator Expansion Module 4-20mA 0-10VDC

The Johnson Controls C450SQN-4 Expansion Module is one of the most useful parts adding to HVAC control systems. It serves as an expansion module, which means that it can accommodate more inputs and outputs and can enable control system to accommodate more signals and devices. The temperatures are -40°F to 185°F and while the module’s power usage of only 1.2W maximizes energy conservation the dependability of the module in various situations is also notable. The C450SQN-4 features a 2-port isolator to ensure that the incoming and the outgoing signals are electrically isolated thus shielding the control system from signal interferences and enhancing the control system’s safety and reliance.
