RTD input module SCM5B34 Series

analogprinted circuit board-mounted

Linearized 2- or 3-Wire RTD Input Module Input Configuration: 2 & 3 Wire RTD Type: 100 Ohm Platinum Input Range: -100 to 100 (°C) Output Range: 0 to +5 V Mechanical Format: Modular plug-in-board Each SCM5B34 RTD-input module provides a single channel of RTD input which is filtered, isolated, amplified, linearized, and converted to a high-level analog voltage output (Figure below). This voltage output is logic switch controlled, which allows these modules to share a common analog bus without the requirement of external multiplexers. The SCM5B module family is designed with a completely isolated computer- side circuit which can be floated to ±50V from Power Common, pin 16. This complete isolation means that no connection is required between I/O Common and Power Common for proper operation of the output switch. If desired, the output switch can be turned on continuously by simply connecting pin 22, the Read-Enable pin, to I/O Common, pin 19.
