1. General Introduction
SDV531 Digital Output Module can be installed on Field Control Unit or Safety node unit for 24VDC Voltage digital on/off status signals field equipment. The output modules can be made dual-redundant respectively. They incorporate field wiring diagnostic functions, so they require no wiring diagnosis elements.
