The 1249 Control Valve Driver provides the drive signal required to operate the MKS 148 and 248 Proportioning Solenoid Valves used for pressure or flow control. It is intended for use with PCs, PLCs, or other controllers that provide the necessary PID control functions, but which do not have the current output necessary to drive these valves.
Enables PC, PLC, or other user- supplied control algorithm to operate a proportioning control valve
Makes use of existing system capabilities to lower the cost of pressure or flow control
Flexible power and signal requirements
Small package can be mounted wherever space is available
±15 VDC ±5% @ 330 mA max. or 24 VDC ±10% @ 270 mA max.(including valve)
Analog: 0-5 VDC, 0-10 VDC or 4-20 mA (user selectable) Digital: TTL or open collector overrides to open or close valve
0 - 50°C
0% to 95% RH non-condensing
Valve open/valve closed LED
Input: 15-pin Type “D” male Output: 9-pin Type “D” female
1.13 inches H x 3.28 inches L x 4.12 inches D (28.7 mm x 83.3 mm x 104.6 mm)
Manual bias pot
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. The 1249 may also be used to drive a 154 Valve if the power applied to the 1249 is ±15 VDC or +30 VDC. Consult Applications Engineering at (800) 227-8766 for details.
