Model 48VTR 1/16 DIN Process Controller
1. INTRODUCTION
The 48VTR is a microprocessor-based device which can compare a process input
(thermocouple, RTD, or analog input) to a user-programmable setpoint and adjust the
process (via relay or analog output), to bring the process to the desired setpoint. This Three-
Mode PID controller offers:
Simultaneous Process Value (PV) and Setpoint Value (SV) display
Automatic alarm functions (11 in all)
Auto-Tuning automatically tailors the controller's response to a specific process
Security lock-out
Ramp-to-Setpoint and Soak functions
