The Allen-Bradley 1746-ITB Current Sinking DC Input Module is a fast-response module for time-critical applications. Terminals have self-lifting pressure plates that accept two 14 AWG (2mm2) wires. LED indicators on the front of the module display the status of each I/O point. Wiring of 16-channel modules can additionally be accomplished with a bulletin 1492 interface module and pre-wired cable. All 16-channel I/O modules are equipped with color-coded removable terminal blocks. If the input module is connected in parallel with an inductive load, use surge suppression across the load to protect the input module form damage caused by reverse voltage.
