Monitor 12 signal per unit with digital input models. These units provide an isolated network interface for discrete logic-level devices with active-high or low inputs. Inputs monitor on/off, high/low, or open/close status of motors, pumps, valves, heaters, fans, and other industrial equipment. Discrete Input Features ♦ 12 I/O channels in a single inch-wide unit reduces system costs and saves panel space ♦ Built-in pull-up/pull-down resistors simplify wiring and lower system costs Control 12 devices from one unit with digital output models. These units provide an isolated network interface to control discrete logic-level devices with high or low-side switching. Outputs control on/off, high/low, or open/close status of motors, pumps, valves, heaters, fans, and other industrial equipment. Discrete Output Features ♦ Bi-directional I/O provides level control and status verification in one unit ♦ Watchdog timers provide a configurable failsafe output state for use when host I/O communication is lost
