These MKS Instruments ULTRA HIGH VACUUM VALVE  have part number UHV-40-ACC-BLVN, are new, and come with full MKS Instruments warranty. The 1249 Control Valve Driver provides the drive signal required to operate the MKS 148 and 248 Proportioning Solenoid Valves, which are used for pressure and flow control. It is intended for use with PCs. PLCs or other controllers that provide the necessary PID control functions, but do not have the current output necessary to drive these valves. (Open-loop control of these valves, i.e. no PID control, is not recommended.) The 1249 can be powered by common power supplies of ±15 VDC or 24 VDC, consuming less than one Watt of power (not including the valve). It accepts control signal inputs of 0-5 VDC, 0-10 VDC, or 4-20 mA from a PC, PLC, or another system controller. The output signal of the 1249 is tailored to match the requirements of the 148 or 248 Proportioning Control Valve.
