Product overview

Chemical or biological hazards. If this instrument is used to monitor a treatment process and/or
chemical feed system for which there are regulatory limits and monitoring requirements related to
public health, public safety, food or beverage manufacture or processing, it is the responsibility of the
user of this instrument to know and abide by any applicable regulation and to have sufficient and
appropriate mechanisms in place for compliance with applicable regulations in the event of malfunction
of the instrument.
The SC4200c is a 2-channel controller for digital sensors. Refer to
The controller is configured and operated with a Mobile sensor management (MSM) software. The
MSM software is accessible through a web application on a customer-supplied device with an
internet browser that is connected to the internet. The controller connects to the MSM software with a
cellular network (optional), WiFi network (optional) or through LAN connection. The MSM software is
also 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
The controller is available with optional expansion modules:
• 4–20 mA analog outputs—Such outputs are commonly used for analog signaling or to control
other 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 in
production (factory) automation applications.
• 4–20 mA analog inputs—The 4–20 mA input module lets the controller accept one external analog
signal (0-20 mA or 4–20 mA).
Note: Only two input devices
