This is a digital input module with 32 inputs. It operates at 120 Volts AC, having a maximum power dissipation of just 5.8 Watts. The 1756-IA32 consumes around 2 mA and has a low cyclic updating time of just 100 microseconds. The operating temperature range is from 0 to 60 degrees Celsius with a non-operating range of -40 to 85 degrees Celsius. The function of this module is to detect actuation signals in the form of High/Low signals that enable the controller to trigger the output signals for any given industrial process.
