Optimal Engineering Systems, Inc. (OES) has released eight DIN Rail Mounted Proportional Valve Controller Modules. These compact, low weight, low cost, highly reliable, Proportional Valve Controller Modules feature both low side and high side drivers.
The freewheeling flyback snubber diodes are present. Designed for open loop operation, they are ideal for: Pressure Control Valves, Flow Control Valves, Solenoids, Actuators, Voice Coil Motors, DC Motors, and Hydraulics. The closed loop version is also available upon request. The input control signals are zero to +5 VDC or zero to +10 VDC.
Microcomputers, PCs, IPCs, and PLCs using programs such as: C/C++, Python, Visual Basic, and LabView TM , can also be used to send simple text messages for control. The RS-232 to TTL module, USB to TTL module, and Ethernet, a LAN, LAN to TTL module, allow other formats of communications to TTL signals.
These modules easily snap onto available DIN Rails, require a single supply from +9 VDC to +50 VDC, have an average current of 4 A, and peak current is 15 A. Off-the-shelf quantities and Just-in-Time deliveries are available.
