NANMAC's F11-40RM is a basic, non-isolated, easy-to-use 2-wire transmitter for DIN EN50022 rail mount use.

Needing no external power supply other than your LOOP Power, the F11-40RM can be used for 3 or 4 wire RTD's, as well as thermocouple types B, C (W5), E, J, K, N, R, S, and T.

RTD inputs can be any of the following standardized RTD’s such as Pt100, Pt500 and Pt1000 according to IEC 60751 (a=0.00385), Pt100 to JIS C 1604 (a=0.003916) and (a=0.003902) as well as Ni100 and Ni1000 to DIN 43760.

Thermocouple input Cold Junction Compensation (CJC) is fully automatic by means of an accurate measurement of the terminal temperature. Alternatively, the CJC can be disabled upon request (see User Specified Information below).

Special note: This non-isolated device should not be used in situations where multiple, grounded junction thermocouple signals are input into each their own transmitter, then all signals are input into the same data acquisition system. Contact the factory for these situations.

Temperature ranges & Specifications &
NOTE: By default, these devices are scaled to the limitations of the RTD or thermocouple type selected, though they may be scaled to a user defined span. Example: Type T thermocouple has a calibrated range of (-)300 to 700 Deg F. The transmitter may be scaled to 100 to 500 Deg F upon user request. This means that the device will have a 4mA output at 100 Deg F and a 20mA output at 500 Deg.F The minimum span in any case is 100 units (Deg. F or C)ecification
