  • Page 7: Product Description

    PORT 2 Inputs The IQAN-XA2 module has eight (8) voltage inputs VIN-A thru VIN-H for connection of 0-5 Vdc signals. The inputs VIN-E thru VIN-H are multi-purpose and for flexibility may be configured in other ways. The two input pins VIN-E and VIN-G can be configured as frequency inputs for measuring frequency.
  • Page 8 IQAN-XA2 Product description Proportional outputs The XA2 module has six (6) double proportional outputs for controlling proportional valves. These outputs can control six bi-directional valve sections or six single solenoid devices (ie. proportional cartridge valves). The proportional outputs can be used in two different modes.

    Addressing/terminating Addressing/terminating Addressing Each IQAN expansion module will have a specific address, enabling the master module to communicate with the modules through the CAN-bus. When operating, the system distinguishes between different modules by first verifying the module type and secondly, through the modules having unique addresses. EXAMPLE If having an expansion module with address 0, the system will denote this one as [module type]-A0, The letter "A"...
