1. General Information
The THCD-101 is a multi-featured process display controller, capable of interfacing directly to a mass flow
meter, mass flow controller or another process transducer such as the HVG-2020 Vacuum Transducer. The
THCD-101 is a single channel unit which can be used to power a bipolar (±15Vdc @ 300mA) or unipolar (24Vdc @
400mA) device. The THCD-101 can display the output from a transducer that supplies voltage signals up to 10
VDC or 4 – 20 mA current signals. There is also an input that can be used for external command (setpoint)
control (+10Vdc full scale). Digital interfaces to the THCD-100 include USB (Serial Port Emulation) and
Ethernet.
Hastings vacuum instruments do not require any periodic maintenance under normal operating conditions with
clean gases. No damage will occur from the use of moderate overpressures (< 25 psig).
The following sections contain the steps needed to get a new power supply operating as quickly and easily as
possible. Please read the following thoroughly before attempting to install the instrument.
