SAB-S
Sensor to serial converter
Overview
The SAB-S-is a two-channel module that measures single or multiple magnet transducer position and returns this information to a host computer via a serial interface using the Modbus or TMX serial Protocol. RS232 or RS485 communications are supported. Sensor interface configuration is controlled via Modbus registers.
Description
The SAB-S module provides a serial interface to two magnetostrictive transducers. The SABS
supports sensors with Start/Stop, PWM (Pulse Width Modulated), or SSI interface. Transducers with
a Start/Stop interface may have from 1 to 32 magnets installed. If they have a single magnet,
they may be recirculated to gain resolution. The module communicates with a host computer or
PLC via RS232/ 485 serial communications using either a simple ASCII protocol or MODBUS
ASCII or RTU.
The SAB-S continually interrogates the magnetostrictive transducers for position and responds to the host with the latest position when it is requested. The serial protocol allows setting of gradient, offset, recirculations and number of magnets. A dip switch allows setup of the base address and baud rate. The module is mounted in a DIN rail enclosure for convenient mounting.
