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.
