MESA 7I37TA  is 8 output 16 input isolated I/O card. The 7I37 is an 8 output, 16 input isolated I/O card. The 7I37 provides 8 Isolated 48VDC 1A output drivers. All output drivers are low saturation voltage MOSFETS for low power dissipation. Each of the 8 output switches is isolated from the others, allowing high side, low side, push-pull and other output switch configurations. The 16 opto isolated inputs will operate with input voltages from 5 to 24 V. Reverse protection diodes are provided to allow use with AC inputs. The 7I37 is compatible with the 4I24M, 4I24H, 4I34M, 4I38, 4I65, 4I68, 5I20, 5I22, 5I23, 7I43 and 7I60 I/O cards. The 7I37T version replaces the 50 pin header output connector with 3.5mm headers compatible with pluggable screw terminal blocks. 7I37 MANUAL DATASHEET
