FW Murphy Temperature Scanner TDXM and TDX6

The TDXM-DC now gives you a unique configurable temperature scanner/pyrometer with a built-in power supply.

A new design features a 7-character, 7-segment Liquid Crystal Display window with 1/2 inch (13 mm), easy-to-read characters. Also located on the faceplate are membrane keys for easy configuring. Highly reliable and versatile, the TDXM-DC accepts up to 24 type J or K grounded or ungrounded thermocouples. Each channel has three adjustable set points SP1, SP2 and SP3. The SP1, SP2 and SP3 set points correspond to the SP1, SP2 and SP3 outputs. Additionally it has the selectable feature to monitor and alarm or shut down on deviation from an average for up to two groups of temperatures (GRP/DEV; deviation from average). One group could be exhaust temperatures, and another group could be bearing temperatures.

The TDXM-DC is capable of communicating with controllers, PLCs, computers or SCADA (Supervisory Control & Data Acquisition) systems by a built-in RS485 serial communications port.

The TDXM-DC is available for 10 - 32 VDC systems.
