The 7I97T is a Ethernet connected motion control interface designed for interfacing  up to 6 Axis of analog servo motor drives and includes encoder feedback for each axis. The 7I97 has 6 +-10V analog outputs and 6 drive enable outputs. The 7I97T also has 16 isolated inputs plus 6 isolated outputs for general purpose I/O use. 6 high speed encoder interfaces are provided axis feedback  and for spindle synchronized motion. A RS-422/RS485 serial expansion ports  and a parallel expansion port are also provided. The encoders can be used with TTL or differential input.
16  isolated inputs are  provided for general control use including limit switch and control panel inputs. Inputs operate with 3V to 36V DC and can have a positive or negative common for sourcing or sinking input applications. 8 inputs can be used to support up to 4 quadrature MPGs.
Six 36V 2A isolated outputs allow sinking, sourcing combinations of both.
A RS-422/RS-485 interface is provided for I/O expansion via a serial I/O daughtercard.  In addition to the on card I/O, A FPGA expansion connector compatible with Mesa's 25 pin daughtercards or standard parallel port breakout boards allow almost unlimited I/O options including additional quadrature or absolute encoder inputs, step/dir or PWM/dir outputs, and field I/O expansion to hundreds of I/O points.  All field wiring is terminated in pluggable 3.5 mm screw terminal blocks. The 7i97T runs from a single 5V supply. The 7I97T is an upgrade to the 7I97 with a larger FPGA.
