I/O Module

The PCE-SM3 DIN rail measuring instrument is suitable for making binary signals or pulse signals bus-capable. It is thus possible, for example, to convert signals from flow sensors, rotary encoders, etc. to RS485 Modbus.

• Input channels: 2
• Inputs: pulse input / binary input
• Interface: RS485 Modbus (ASCII RTU)
• Power supply: 85 … 253 V / 20 … 50 V AC/DC (selectable)

The DIN-Rail Measuring Instrument PCE-SM1 is suitable for making analog signals bus-capable. Various analog signals such as 0 … 20 mA, 0 … 10 V, PT100 etc. are converted from the analog input module to RS485 Modbus.

• Input channels: 2
• Inputs: PT100, 0/4 … 20 mA, 0 … 10 V, 0 … 40 Ω
• Interface: RS485 Modbus (ASCII RTU)
• Power supply: 85 … 253 V / 20 … 50 V AC / DC (selectable)

To connect the DIN rail measuring instrument PCE-SM4 via the Modbus machines. This makes it possible to initiate various processes via the H-rail measuring device via a connected HMI.

• Output channels: 4 or 8 (selectable)
• Outputs: 4 relays or 8 OC (selectable)
• Interface: RS485 Modbus (ASCII RTU)
• Voltage supply: 85 … 253 V / 20 … 50 V AC / DC (selectable)

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

The DIN-rail measuring instrument has an adjustable measuring range of 0… 600 V AC/DC and can therefore measure a wide variety of voltages. For example, it is possible to connect the transmitter to the supply line in order to monitor the applied voltage.

• Measuring range 0 … 600 V AC/DC
• Active and passive output signal
• Display and keypad for configuration
• Frequency measurement
• DIN rail mounting
• Display

The PCE-SM2 DIN rail measuring device is suitable for making analog signals bus-capable. Different analog signals such as 0 … 20 mA, 0 … 10 V, PT100 etc. are converted from the DIN rail measuring instrument to RS485 Modbus. The transmission method via Modbus is RTU or ASCII. The DIN rail measuring device is mounted on a DIN rail. The DIN rail measuring device is parameterized via the front-end RS232 interface and the configuration software.

• Input channels: 4
• Inputs: PT100, 0/4 … 20 mA, 0 … 10 V, 0 … 40 Ω
• Interface: RS485 Modbus (ASCII RTU)
• Power supply: 85 … 253 V / 20 … 50 V AC/DC (selectable)
