Pressroom Electronics is an electronic design and manufacturing company that specializes in punch press operator controls and punch press automation controls for the metal stamping industry. These “control reliable” control systems are designed for operator safety, ease of operation and to enhance productivity. The enhanced punch press efficiency correlates to an improved OEE (Overall Equipment Efficiency) of the punch press manufacturing process.
The punch press operator controls are designed to be a compatible retrofit for existing punch presses or for OEM punch press manufacturers that produce part revolution/air clutch, pneumatic or hydraulic machines by design. The control systems also meet or exceed OSHA, ANSI, CSA and international standards for safety in design and productivity. Pressroom Electronics offers many different standard retrofit packages that can also be customized to meet the needs of unique and various production requirements.
The punch press control products are available with a multitude of features that provide enhanced press safety and functionality. The following is a partial listing of features and functions that the resolver based “Presscommander” press control contains:
• Exceeds OSHA 1910.217 & ANSI B11.1-2009
• Quick and Easy Installation
• Control Reliable Design (Triple CPU Redundancy)
• Incorporates dual logic power supplies
• Heavy duty resolver with self-checking input on every press cycle with 30’ of resolver cabling supplied standard
• Complete system diagnostics and programming in plain English/Spanish by a four line by twenty character vacuum fluorescent display
• Optional: 10.1” color touchscreen display replaces the standard display shown.
• Can control up to four sets of operator stations (2 operators standard)
• Operates at 24VDC, 110VAC, or 240VAC / 440VAC
• Major faults such as E-Stop, motion, brake monitor, and sensor faults are handled by two force-guided relays (Form B safety relays)
• Modes of operation: off–inch–single–continuous
• Continuous ARM; top stop, anti-tie down and anti-repeat
• System start/stop functions
• SPM Range -1 to 500
• Password and supervisory controlled keyed selector switch for security of data entry
• Interrupted stroke provision with indicator
• Inch mode monitoring
• Crank angle and speed readout (SPM)
• Time-based brake monitor
• Built-in motion detector and drift fault
• 90º and 270º stop time tester/meter built-in
• Built-in variable speed compensation
• Servo-feed interface built-in
• Six optically isolated die protection inputs that can be either AC or DC (sourcing or sinking) (Expandable)
• Six limit switch outputs can be set to cycle (non- timed) two times per crank rotation by setting an open/close crank angle (Expandable)
• The last three limit switch outputs can be set for timed, non-timed, delay, hold, or cycle two times per crank revolution.
• Six PLS (programmable limit switch) output relays are small, high speed, and high capacity. These outputs can be controlled by the press crank angle position, dwell time, number of strokes or any combination of the above. (Expandable)
• Optional “Expander” board provides an additional six Die Inputs and six Programmable Outputs.
• 100 job memory (removable)
• Stroke, batch, quality, and part counters
• Batch counter output relay
• Die protection output relay (opens when there is a fault)
• Speed output relay (opens when press speed falls out of the max/min parameters)
• Auxiliary output relay (customer assigned usage)
• Optional Ethernet or CAN network
• Remote monitoring with Ethernet
• PC Link to allow offline job creation and storage
• Optional Tonnage Monitoring
• Two-year warranty
• Made in the USA
