The JTS Bench Test setup allows for testing, troubleshooting and repair for various GE Fanuc Series 90-70 PLC circuit boards and modules. Some successful examples of testing and repairs include:

• IC697CPU731, CPU - Central Processing Unit.
• IC697MDL750F, Discrete Output Module 24/48 Volt DC
• IC697MDL350E, 32-Point Output Module 120 Volt AC
• IC697MDL250F, Discrete Input Module 120 Volt AC 32-Point
• IC697ALG320D, High Level Analog Outputs, 4 Channel, Voltage/Current Module
• Others possible, let us know your needs!

JTS has the capability to test and repair RTP circuit boards and modules. This includes support for the Universal Input/Output rack as well as the various analog and digital input/output cards.

JTS has constructed a test bench for the support of these system components, which includes a RPT 7431 Universal Input/Output Controller and a RTP 7505/05 Control Panel. In addition, through a HP1000 host computer with a IOBC I/F board connected to the RTP 7431 Universal Input/Output Controller the test bench can test communications from host to the RTP universal rack and the input, output boards.

We provide repairs and full functional checkout of the whole series of Analog Input, Analog Output, Digital Input, and Digital Output cards.  Some  already serviced: RTP7437/37 Digital Input Card, RTP 7437/83 Digital Output Card, RTP7455/30 D/A Converter Card, RTP 7436 Analog Input Card Set, and others. A detailed checklist of parameters checked and their measured values are also available for ISO or other regulatory organizations.  Please feel free to contact us if you have any need or questions for support about RTP system components support.

JTS has the capability to test and repair various circuit boards and modules used in DEC LSI-11 CPU based systems, this includes LSI-11 based QBUS system used in measurement and controls systems, PDP-11 systems, and Micro-VAX II. JTS has various QBUS sub-systems that are used for testing QBUS system circuit boards. JTS writes short programs in LSI-11 machine code for the testing of these boards.

• Testing and some repairs of LSI-11 CPU boards, including the LSI-11/93 and Mentec M100
• Testing and repairs of memory boards
• Testing and repairs of I/O boards
• Testing and repairs of Measurex I/O boards used in their QBUS applications
• Software archiving and hard drive formatting, defect sparing, and loading application software?? check on this!

JTS does testing and repairs of ABB Actuator Drive Modules, P# 134152-125 that are used in Profile IT Slice/Coat Weight Profiler Systems. These Drive Modules are part of actuator P# 134157-025. The actuators control the slice lip opening on a paper machine headbox to regulate the cross direction profile of the paper.

JTS has constructed a test bench dedicated entirely for operating and testing these Drive Modules. JTS tests these modules and if they are out of spec or non-functional, determines what repair actions are needed to get them back to 100% operation. A test report is returned with each module to the customer indication key measured parameters of the drive unit.

Feel free to contact JTS if you have any of these units that need to checked out and/or repaired.

JTS provides terminal emulators for terminals that are obsolete or hard to find. The JTS-provided terminal emulators are mini-PCs mounted on the rear of the display monitor VESA mount. The mini-PC runs a terminal emulator software to interface to the operator, and communicates via one of its RS232 serial ports to the host computer, (an Ethernet connection is possible). The video quality and resolution, as you can imagine, is multiple times better than the original terminal types.

We currently provide 17 or 19 inch VGA monitors, but different sizes and video interfaces are available, (HDMI for example). The photo on the left shows an example of one of these VESA-mounted terminal emulators; it is running Reflections software and is configured for use with HP host computers. Emulations are available for HP, DEC, and others like IBM may be available. Feel free to contact JTS with any questions or desired needs.

JTS provides Solid State Drives to replace old hard drives that are either hard to find or no longer reliable. These upgrades can assure you that your system computer will have many more years of life with reliable SSD drives. Currently we are providing for SCSI bus and MFM interface hard drives.  

SD card devices are also available for the narrow SCSI bus. These SD cards can be configured as a hard drive, or a floppy drive device so you can replace 3.5" floppy drive devices with a SD card device. Being removable media, you can make as many copies as you want and store them in safe places.
