The I/O module PCE-SM4AI has 4 analog inputs for process signals, thermometers etc. All inputs from the I/O module are individually programmable. The I/O module is used to provide analog measurement signals in a Modbus network.

• 4 analog inputs
• Modbus RTU slave
• 2 programmable alarm outputs
• USB interface for programming
