Thermocouple and RTD interface for RIO Pocket PLC


General DPN

Galil Motion Control, developer of the RIO Pocket PLC series for intelligent and cost-effective I/O handling, has introduced the SCB-48x06 signal conditioning board which allows the RIO to interface with thermocouples and RTDs (Resistive Temperature Device).

The SCB-48206 interfaces to 6 RTDs and the SCB-48306 interfaces to 6 thermocouples or the SCB-48206 interfaces to up to 6 RTDs and the SCB-48306 interfaces to up to 6 thermocouples.

The SCB-48×06 connects directly to the 26-pin d-sub connector of the RIO-47120 and is oriented vertically from the RIO connector. Other mounting options are available on request. The RIO is said to provide an intelligent, low-cost and compact solution for handling I/O. Each RIO unit contains 16 analog I/O and 32 digital I/O. Multiple RIO units can be networked together for unlimited I/O expansion. The RIO has a fast, 32-bit processor and non-volatile memory for storing programs.

Features include arithmetic and logical processing, data logging, process control loops, counters and timers. The RIO allows communication via both Ethernet and RS232. It also supports Modbus TCP/IP as master and slave, a web interface and the ability to send email alerts. It can easily interface with HMIs, PLCs, motion controllers and other I/O devices. The RIO is programmed with Galil’s intuitive two-letter commands or Ladder Interface Software.
