Section 1 Introduction Installation and Operation Manual
X-TMF-5965-5851EM-MFC-eng
Part Number: 541B122AAG

• Remote transducer input (Note 1) is accessed via terminal 5 on the
Card Edge or Pin 15 on the D-Connector version. This feature allows
the use of the integral control electronics and valve to regulate flow in
response to the signal from an external 0-5 Vdc signal. The mass flow
signal from the Model 5965/5851EM is still available for process
monitoring. This function is enabled at the factory. Refer to section 2-6.
Note 1: Feature not available with 4-20 mA I/O option.
• Fast response control permits rapid gas settling times with minimal
over/undershoot.
