The Quad Input/Output Module connects directly to the MZX Digital loop and provides four change over relay outputs, four High Voltage Relay (HVR) outputs and four monitored inputs. It is loop powered and therefore does not need a power supply*, however it can monitor the presence of a local 24Vdc or 48Vdc power supply. * A 24Vdc power supply will be required if the module is controlling HVR’s switching 240Vac. Features: Four change over relay outputs and four monitored inputs each individually programmable for a wide range of applications Four HVR drivers* Inputs can monitor normally open or normally closed contacts The relay contacts are monitored and users are alerted to “output stuck” conditions Uses 2 addresses when configured for 2 inputs with 2 associated outputs Uses 4 addresses when configured for 4 inputs with 4 associated outputs Uses 8 addresses when configured for 4 inputs and 4 independent outputs Compact DIN rail mount design saves space Lower installation costs than individual modules Built-in line isolators improve fault tolerance Status LED’s provide rapid diagnostics Two way IR communication to the 850EMT programming tool speeds up commissioning Monitors input power supply for improved system integrity VdS and CPD approved to EN54-17, EN54-18 and EN54-13 555.800.073 Datasheet Download 555.800.073 Datasheet Show more
