If this instrument is used to monitor a treatment process and/orchemical feed system for which there are regulatory limits and monitoring requirements related topublic health, public safety, food or beverage manufacture or processing, it is the responsibility of theuser of this instrument to know and abide by any applicable regulation and to have sufficient andappropriate mechanisms in place for compliance with applicable regulations in the event of malfunctionof the instrument.The SC4200c is a 2-channel controller for digital sensors. Refer to Figure 1.The controller is configured and operated with a Mobile sensor management (MSM) software. TheMSM software is accessible through a web application on a customer-supplied device with aninternet browser that is connected to the internet. The controller connects to the MSM software with acellular network (optional), WiFi network (optional) or through LAN connection. The MSM software isalso referred as Cloud in this manual.Note: The controller uses one ethernet port for Modbus TCP/IP based fieldbus communication with PLC/SCADA.Refer to Modbus TCP/IP on page 19.The controller is available with optional expansion modules:• 4–20 mA analog outputs—Such outputs are commonly used for analog signaling or to controlother external devices.Note: Only one module can be connected.• Profibus interface—Used to connect the controller to a Profibus DP (Decentralised Peripherals)network. PROFIBUS DP is used to operate sensors and actuators via a centralised controller inproduction (factory) automation applications.• 4–20 mA analog inputs—The 4–20 mA input module lets the controller accept one external analogsignal (0-20 mA or 4–20 mA).Note: Only two input devices3 can be connected to the controller at the same time. Refer to the moduledocumentation for additional information.3 Input devices are mA input modules or digital sensors.English 7
