The D1040 series are quad channel DIN Rail Digital Output Modules enabling a Safe Area contact, logic level or drive signal, to control a device in Hazardous Area, providing 3 port isolation (input/output/supply). Typical applications includes driving signaling LED’s, visual or audible alarms to alert a plant operator or driving a solenoid valve or other process control devices.
It can also be used as a controllable supply to power measuring or process control equipment in Hazardous Area. Output channels can be paralleled if more power is required; 2 or 3 channels in parallel (depending on the model) are still suitable for Gas Group II C. Four basic models meet a large number of applications: it is possible to obtain 16 different combinations of safety parameters and driving currents.
